Aetna Physical Therapy Coverage: Approved CPT Codes, Authorization Requirements, and the Complete Provider Guide
If you’ve ever had an Aetna claim denied for physical therapy services — or spent hours trying to navigate prior authorization before your patient’s first appointment — you are not alone. Aetna is one of the largest commercial health insurers in the United States, and understanding exactly how its physical therapy policies work can mean the difference between a smoothly reimbursed caseload and a revenue-destroying cycle of denials and appeals.
This guide breaks down everything you need to know about Aetna’s face-to-face physiotherapy coverage: which CPT codes are approved, what medical necessity criteria actually require, when and how to request prior authorization, how visit limits work, what Aetna considers experimental, and how to fight a denial effectively. Whether you’re a physical therapist, a practice manager, or a biller, this is the reference document you’ll return to every quarter.
What Is Aetna’s Physical Therapy Coverage Policy?
Aetna’s coverage of physical therapy services is governed primarily by Clinical Policy Bulletin (CPB) 0325, which is publicly available on Aetna’s website and updated periodically. This is the foundational document that defines medical necessity, approved and excluded procedures, coding requirements, and documentation standards for all physical therapy claims.
Under CPB 0325, Aetna considers physical therapy medically necessary when it is designed to “significantly improve, develop or restore physical functions lost or impaired as a result of a disease, injury or surgical procedure.” The policy does not leave this vague — it defines specific, documented criteria that must all be satisfied simultaneously for coverage to apply.
Key Fact: Aetna’s physical therapy policy applies across commercial, Medicare Advantage, and Medicaid managed care plans, but the specific benefit limits, co-pays, and authorization requirements differ by plan type and the member’s state of enrollment. Always verify the member’s specific plan before initiating treatment.
Why CPB 0325 Matters to Every PT Provider
CPB 0325 is not just bureaucratic language — it is the clinical and legal framework Aetna adjusters use to adjudicate your claims. When you understand exactly what is written in that document, you can structure your documentation to satisfy every criterion before you submit, dramatically reducing your denial rate.
The policy applies to:
- Outpatient physical therapy in clinic settings
- Home-based physical therapy (when clinically justified)
- Physical therapy provided under physician supervision
- Services delivered by physical therapy assistants (PTAs) under licensed PT supervision
Aetna’s Medical Necessity Criteria for Physical Therapy
Aetna’s definition of medical necessity for physical therapy is multi-part. Every condition listed below must be documented and justified in your plan of care for the claim to pass a medical necessity review.
The Five Core Medical Necessity Requirements
- Measurable improvement expected within one month: A licensed healthcare practitioner must determine that the member’s condition can improve significantly based on objective physical measures — active range of motion (AROM), strength, function, or pain level — within the first 30 days of therapy beginning. Alternatively, services must be necessary to establish a safe maintenance program.
- Reasonable expectation of significant improvement: PT services must cover only episodes where there is a reasonable expectation that the member’s condition will improve significantly within a generally predictable period of time. Open-ended, indefinite treatment plans do not satisfy this requirement.
- Licensed provider performing or supervising services: All PT services must be performed by a duly licensed and certified physical therapist. Services performed by a PTA must be under licensed PT supervision at the level required by the applicable state law.
- Complexity requiring a licensed therapist’s skills: The services must be of a complexity and nature that requires the judgment, knowledge, and skills of a licensed professional therapist. Routine reinforcement exercises that can be safely performed by the patient independently do not meet this bar.
- Written, ongoing plan of care: PT must be provided in accordance with a written plan of care containing sufficient objective and subjective data to demonstrate medical necessity. Aetna’s Appendix A within CPB 0325 outlines documentation requirements in detail.
Warning: Aetna explicitly considers physical therapy not medically necessary in three situations: (1) for asymptomatic persons or those without an identifiable clinical condition; (2) for persons whose condition is neither regressing nor improving; and (3) once therapeutic benefit has been achieved or when a home exercise program could be used for further gains. Documenting a plateau in progress is the fastest path to a denied claim.
What Counts as a “Plateau”?
A plateau is defined by Aetna as a period of four weeks — or a shorter period depending on the specific condition — during which no significant progress is observed. Once a plateau is documented, continued supervised PT is no longer considered medically necessary under standard policy. To avoid triggering this clause, your progress notes must consistently document objective, measurable functional gains at every visit.
Approved Aetna CPT Codes for Face-to-Face Physical Therapy
This section covers the CPT codes Aetna covers under CPB 0325 when medical necessity and all selection criteria are satisfied. These are the codes your billing team should know by heart.
Physical Therapy Evaluation and Reevaluation
| CPT Code | Description |
|---|---|
| 97161 | PT evaluation, low complexity, 20 minutes |
| 97162 | PT evaluation, moderate complexity, 30 minutes |
| 97163 | PT evaluation, high complexity, 45 minutes |
| 97164 | PT reevaluation, 20 minutes |
These codes are covered for both initial evaluation and clinical reassessment. They are the gateway to all subsequent treatment codes and must be documented with the appropriate complexity level justified by the clinical presentation.
Therapeutic Modalities (Timed and Untimed)
| CPT Code | Description | Timed? |
|---|---|---|
| 97010 | Hot or cold packs | No |
| 97012 | Mechanical traction | No |
| 97014 | Electrical stimulation, unattended | No |
| 97016 | Vasopneumatic devices | No |
| 97018 | Paraffin bath | No |
| 97022 | Whirlpool | No |
| 97024 | Diathermy (e.g., microwave) | No |
| 97026 | Infrared | No |
| 97028 | Ultraviolet | No |
| 97032 | Electrical stimulation, manual, each 15 min | Yes |
| 97033 | Iontophoresis, each 15 min | Yes |
| 97034 | Contrast baths, each 15 min | Yes |
| 97035 | Ultrasound, each 15 min | Yes |
| 97036 | Hubbard tank, each 15 min | Yes |
Expert Tip: Modalities like hot/cold packs (97010) and unattended electrical stimulation (97014) are generally not billable alone — they must be accompanied by skilled therapeutic procedures that justify the therapist’s involvement. Billing modalities in isolation is a common trigger for medical necessity denials.

Therapeutic Procedures (Face-to-Face, Active Codes)
These are the core face-to-face physical therapy CPT codes that drive the bulk of outpatient billing. Each is billed per 15-minute unit.
| CPT Code | Description |
|---|---|
| 97110 | Therapeutic exercises (strength, endurance, ROM, flexibility) |
| 97112 | Neuromuscular reeducation (balance, coordination, proprioception) |
| 97113 | Aquatic therapy with therapeutic exercise |
| 97116 | Gait training, including stair climbing |
| 97124 | Massage (effleurage, petrissage, tapotement) |
| 97129 | Therapeutic interventions targeting cognitive function, initial 15 min |
| +97130 | Cognitive therapeutic interventions, each additional 15 min |
| 97140 | Manual therapy (mobilization/manipulation, manual lymphatic drainage, manual traction) |
| 97530 | Therapeutic activities, direct one-on-one, to improve functional performance |
| 97535 | Self-care/home management training (ADL, safety, assistive technology) |
| 97537 | Community/work reintegration training |
| 97542 | Wheelchair management and training |
| 97760 | Orthotic management and training, each 15 min |
| 97761 | Prosthetic training, upper and/or lower extremity, each 15 min |
| 97763 | Orthotics/prosthetics management and training, subsequent encounter |
Key Fact: Aetna’s Texas Medicaid plan limits timed therapeutic procedure codes — including 97110, 97112, 97113, 97116, 97124, 97140, and 97530 — to a combined total of 4 units (one hour) per date of service per discipline. This does not apply universally across all plan types, but it is a critical billing ceiling to verify for your specific patient population.
Group and Unlisted Procedure Codes
| CPT Code | Description |
|---|---|
| 97150 | Therapeutic procedure, group (2 or more individuals) |
| 97039 | Unlisted modality (specify type and time if constant attendance) |
| 97139 | Unlisted therapeutic procedure |
HCPCS Codes for Home Health and Hospice Settings
| HCPCS Code | Description |
|---|---|
| G0151 | Services by qualified PT in home health or hospice, each 15 min |
| G0159 | PT maintenance program in home health setting, each 15 min |
| S9131 | Physical therapy in the home, per diem |
CPT Codes Aetna Does NOT Cover for Physical Therapy
Understanding what Aetna considers experimental, investigational, or unproven is just as important as knowing the covered codes. Billing these services will result in automatic denial regardless of documentation quality.
Experimental and Investigational Services (CPB 0325)
Aetna classifies the following as experimental or unproven — meaning they do not have a covered CPT code under the PT policy:
- Blood flow restriction (BFR) therapy — explicitly excluded despite growing clinical adoption
- Kinesio Taping / McConnell Taping — excluded for all indications, including back pain, knee pain, ankle sprains, and post-operative care
- Virtual reality–facilitated gait training — CPT +0791T is explicitly not covered
- MEDEK therapy — excluded
- Hivamat therapy (deep oscillation therapy) — excluded
- Interactive Metronome program — excluded for all indications
- Applied Functional Science — excluded
- Dynamic Movement Intervention — excluded (note: 97530 is covered except for Dynamic Movement Intervention)
- Adhesion removal physical therapy for bowel obstructions — excluded
- Low-dye strapping and chest strapping — excluded
- Hands-free ultrasound and infrasound — excluded
- RomTech PortableConnect — excluded
- Ultrasound for Dupuytren’s contracture — excluded
Warning: CPT code 97530 (therapeutic activities) is covered under Aetna’s policy except when used for Dynamic Movement Intervention. If your documentation references DynMI or similar trademarked protocols tied to excluded categories, your 97530 claim may be denied even though the code itself is covered.
Four PT Methods Not Covered Out-of-Network When In-Network Alternatives Exist
Aetna’s policy specifically states there are “no reliable data demonstrating that the following methods are superior to standard PT”:
- McKenzie Method of Mechanical Diagnosis and Therapy
- Muldowney Method of Physical Therapy
- Muscle Activation Techniques (MAT)
- Postural Restoration Form of Physical Therapy
This means Aetna will not approve out-of-network coverage for these methods when standard in-network PT is available. Patients choosing these methods out-of-network do so at their own financial risk unless you document clinical necessity for the specific method.
Aetna Physical Therapy Visit Limits by Plan Type
Visit limits are one of the most misunderstood aspects of Aetna’s PT policy, and misunderstanding them is one of the most common reasons for unexpected claim denials.
HMO and Managed Care Plans
Under standard Aetna HMO plans, physical therapy is limited to a 60-day treatment period per condition. This is a critically important nuance: the 60-day limit applies per condition, not per calendar year.
Key points:
- A surgical procedure triggering PT is considered the start of a new condition, resetting the clock
- An exacerbation or flare-up of a chronic condition is not considered a new condition — it does not reset the 60-day limit
- Some plan designs apply the 60-day limit on a calendar year or contract year basis; others apply it as a lifetime limit per condition
- Short-term home PT in HMO plans accumulates toward the 60-day limit
PPO and Other Plan Designs
Some PPO and non-HMO plans define the PT benefit as a maximum number of sessions per year, regardless of condition or number of therapy courses. For example, one documented plan design covers 75 visits of PT, OT, or ST per condition per plan year, with visits exceeding 75 subject to medical necessity review.
When Aetna Removed Prior Authorization in Select States
Beginning January 1, 2023, Aetna eliminated the prior authorization requirement for physical medicine services in Delaware, New Jersey, New York, Pennsylvania, and West Virginia. Additionally, effective February 1, 2024, Aetna Better Health Medicaid plans in Kentucky removed the authorization requirement for the initial 20 outpatient PT visits per member per year, with authorization required only for visits beyond that threshold.
Expert Tip: State-level authorization rules can change rapidly. Always verify current authorization requirements by checking Aetna’s provider portal or calling the number on the patient’s member ID card before initiating treatment — even in states where PA was recently waived.
How to Get Aetna Prior Authorization for Physical Therapy
When prior authorization is required for your patient’s plan and location, getting it right the first time saves you hours of follow-up and protects your revenue.
Step-by-Step Prior Authorization Process
- Verify eligibility and benefits first: Log into the Aetna provider portal or call Member Services to confirm the member’s active coverage, plan type, applicable visit limits, and whether prior authorization is required for PT services under their specific plan.
- Prepare your clinical documentation package: Aetna requires the following supporting documentation for a PT authorization request:
- ICD-10 diagnosis code(s) with description
- CPT/HCPCS code(s) being requested with description
- Number of units or visits requested and service date range
- Clinical indications and rationale for the requested services
- Relevant diagnostic test results, imaging reports, lab values
- Documentation of conservative treatments already tried without success
- Complete medication list
- Written plan of care
- Submit the prior authorization request: You have three channels available:
- Online: Submit through the Aetna provider portal (fastest method, real-time tracking)
- By phone: Call the number on the member’s ID card (for Aetna Better Health Illinois Medicaid: 1-866-329-4701)
- By fax: For commercial plans, fax to 859-455-8650 with the request form and all supporting documents
- Monitor for the authorization decision: Standard decisions come within the plan’s required timeframe; urgent/expedited requests require a faster turnaround when a clinician certifies that waiting would harm the patient’s health.
- Document the authorization number: When authorization is approved, record the authorization number in the patient’s chart and reference it on every subsequent claim submission.
Key Fact: Incomplete authorization requests are one of the top reasons for delays. Aetna’s PA forms explicitly state: “Incomplete requests will delay the prior authorization process.” Always attach all supporting clinical documentation at the time of initial submission — do not wait for Aetna to request it.
What to Do if Authorization Is Denied
An authorization denial is not the end of the road. Aetna’s appeals process provides multiple levels of review, and the clinical evidence is on your side for medically necessary PT.
Required Modifiers for Aetna Physical Therapy Claims
Billing modifiers are not optional for Aetna — missing or incorrect modifiers are a common cause of claim rejection and underpayment.
PTA and OTA Differential Payment Modifiers
Effective December 1, 2023, Aetna began separately reimbursing Physical Therapy Assistants and Occupational Therapy Assistants at 85% of the allowed amount when services are provided in part or in whole by a PTA or OTA. Two modifiers are mandatory:
| Modifier | When to Use |
|---|---|
| CQ | Physical therapy services performed in part or in whole by a Physical Therapy Assistant |
| CO | Occupational therapy services performed in part or in whole by an Occupational Therapy Assistant |
Failure to append CQ when a PTA performs PT services will result in either claim rejection or overpayment recovery during a post-payment audit.
Telehealth Modifiers for PT Services
For physical therapy services delivered via telehealth (two-way synchronous audiovisual), Aetna requires one of the following modifiers:
- GT — Via interactive audio and video telecommunication systems (original telehealth modifier)
- 95 — Synchronous telemedicine service rendered via real-time interactive audio and video telecommunications technology (more recent standard)
Telehealth-covered PT codes (as of Aetna’s most recent update): 97110, 97112, 97116, 97161, 97162, 97530, 97537, 97755, 97760, 97761, 97750
Warning: Aetna discontinued coverage of communication-based technology services for PT, including E-Visits (98970-98972), virtual check-ins (G2251, G2252), and telephone assessment codes (98966-98968). Additionally, certain codes including 97129, 97130, 97150, 97163, 97164, and 97542 are no longer covered when delivered via telehealth under current Aetna policy. Verify the current telehealth code list before billing.
GP Modifier for Physical Therapy Plan of Care
When delivering services under a physical therapy plan of care, always append the GP modifier to the service code. This modifier indicates the service was delivered under an outpatient PT plan of care and is required for claims under many Aetna managed care and Medicaid plans.
Aetna Physical Therapy Documentation Requirements
Your clinical documentation is not just a clinical record — it is your legal defense against a claim denial or audit. Aetna’s CPB 0325 includes detailed documentation requirements in its Appendix A that go beyond what most standard SOAP notes cover.
What Every PT Note Must Include for Aetna
- Objective baseline measurements: AROM, strength grading, pain scale, functional status — documented at evaluation and consistently updated
- Measurable functional goals: Goals must be specific, measurable, and time-bound, with a clear target date for achievement
- Evidence of progress: Every visit note must document objective change from the previous session. Subjective improvement alone (e.g., “patient reports feeling better”) is insufficient for continued medical necessity
- Justification for continued skilled care: Explain why the services require the skills of a licensed PT versus what the patient could safely do independently
- Written plan of care: A signed, dated plan of care with diagnosis, treatment goals, frequency, duration, and modalities planned — updated whenever significant clinical changes occur
- Physician or practitioner order: While Aetna recognizes direct access in applicable states, a PT may qualify as “other health professional qualified to prescribe physical therapy” in direct access states — but documentation of the authorization source must be present in the chart
Expert Tip: Aetna’s medical necessity reviewers specifically look for documentation of why the patient requires a licensed therapist’s judgment at each session. If your notes read like a list of exercises performed rather than a skilled clinical narrative, expect increased scrutiny. Frame every note around what clinical decisions you made and why.
Sports Rehabilitation Exclusion: What Aetna Does and Does Not Cover
The sports rehabilitation exclusion is one of the most commercially significant limitations in Aetna’s PT policy, and it trips up providers who treat active or athletic populations.
What Is Excluded Under the Sports Rehabilitation Clause
Aetna defines sports rehabilitation as “continued treatment for sports-related injuries in an effort to improve above and beyond normal ability to perform activities of daily living (ADLs).” Under this definition, the following are not covered:
- Baseball pitching/throwing rehabilitation programs
- Cheerleading, martial arts, or dance performance training
- Organized team sports rehabilitation at the college, high school, or community level (football, basketball, soccer, lacrosse, swimming, track, tennis)
- Competitive weightlifting rehabilitation
- Professional and amateur sports performance optimization
What Is Still Covered for Athletes
The key distinction is functional restoration to ADL level versus performance enhancement beyond ADL level. Aetna will cover PT for an athlete recovering from an ACL reconstruction up to the point where the patient can safely perform normal activities of daily living. Once the goal shifts to optimizing sport-specific performance, the remaining treatment falls outside the covered benefit.
This distinction has significant practical implications for clinicians in sports medicine settings. Document your goals in functional ADL terms — walking without pain, climbing stairs, returning to work — rather than sport-specific performance metrics, to preserve coverage eligibility throughout the rehabilitation timeline.
How to Appeal a Denied Aetna Physical Therapy Claim
Denials happen even with pristine documentation. Knowing Aetna’s dispute and appeals process — and the precise timelines involved — is essential for recovering revenue you’ve legitimately earned.
The Three-Stage Dispute and Appeals Process
Stage 1: Reconsideration (Dispute)
- You must file your reconsideration within 180 calendar days of the initial claim decision
- Include: medical records, office notes, other supporting documents, a written explanation identifying the denied codes and the reason for review, plus member ID and claim details
- Submission options: online via the Availity provider portal, by mail, or by fax to the address on the denial letter or EOB
- Expected decision: within 30 business days of receipt in most cases
Stage 2: Appeal
- If reconsideration is denied, file your appeal within 60 calendar days of the reconsideration decision
- For Medicare plans: up to 180 days for commercial and Medicare; up to 65 days for Medicare non-contracted providers
- Required documents: completed dispute and appeal form, written explanation of disagreement, supporting records, denial letter or EOB
- Decision timeline: Aetna will issue a written decision within 60 business days of receiving the appeal (or any additional information requested)
- For urgent/expedited appeals: decisions within 72 hours when a physician certifies waiting may harm the patient
Stage 3: External Review
- If the internal appeal is unsuccessful, you may have the right to request an external review by an independent organization, depending on your state’s insurance regulations and the type of plan
Key Fact: For Medicare Advantage plan appeals specifically, providers in the Aetna network must submit appeals within 65 days of the denial notice date. The appeal form, supporting medical records, and a clear statement of why the service is medically necessary should all be submitted simultaneously — not sequentially — to avoid processing delays.
Building a Strong Appeal Letter
The most effective Aetna appeal letters include:
- A direct citation to the specific criteria in CPB 0325 that the service satisfies
- Objective clinical data showing measurable patient progress
- Peer-reviewed literature supporting the clinical necessity of the denied service
- A clear statement of how the denial contradicts Aetna’s own stated coverage criteria
- If applicable, a letter from the supervising or referring physician reinforcing medical necessity
Direct Access States: Do You Need a Physician Referral?
One of the most practically important — and frequently misunderstood — aspects of Aetna’s PT policy involves physician referrals in direct access states.
Aetna’s Official Position on Direct Access
Aetna’s policy states that it “considers physical therapy medically necessary when this care is prescribed by a chiropractor, DO, MD, nurse practitioner, podiatrist or other health professional qualified to prescribe physical therapy according to state law.”
In states with direct access provisions for physical therapists, Aetna has confirmed — through communication with the APTA — that a licensed PT qualifies as “other health professional qualified to prescribe physical therapy.” This means that in direct access states, PT services will be reimbursed without a physician order or referral if all other requirements are met.
However, not all Aetna plans honor direct access equally. HMO plans in particular may still require a referral from a primary care physician even when state law allows direct access. Always verify at the plan level before assuming direct access applies to your patient’s specific coverage.
FAQ: Aetna Physical Therapy Coverage
Q1: What CPT codes does Aetna cover for face-to-face physical therapy?
Aetna covers a broad range of PT CPT codes under CPB 0325 when medical necessity criteria are met. The most commonly billed face-to-face codes include 97110 (therapeutic exercises), 97112 (neuromuscular reeducation), 97116 (gait training), 97140 (manual therapy), 97530 (therapeutic activities), and the evaluation codes 97161-97164. Modalities such as 97010 (hot/cold packs), 97014 (electrical stimulation unattended), and 97035 (ultrasound) are also covered but typically cannot be billed alone without accompanying skilled therapeutic procedures.
Q2: Does Aetna require prior authorization for physical therapy?
It depends on the member’s specific plan and state. As of January 2023, Aetna waived prior authorization for PT in Delaware, New Jersey, New York, Pennsylvania, and West Virginia. Aetna Better Health Medicaid in Kentucky removed the PA requirement for the first 20 outpatient PT visits per member per year effective February 2024. For all other plans and states, prior authorization is typically required and must include a written plan of care, ICD-10 codes, CPT codes, clinical rationale, diagnostic results, and documentation of prior conservative treatment attempts.
Q3: How many physical therapy visits does Aetna cover per year?
Visit limits vary by plan type. Standard Aetna HMO plans typically limit PT to a 60-day treatment period per condition. Some PPO plan designs allow up to 75 visits per condition per plan year, with visits beyond that threshold subject to medical necessity review. A new course of PT for a new condition (such as post-surgical rehabilitation for a different body part) restores coverage eligibility. Always verify the specific member’s benefit plan.
Q4: Does Aetna cover blood flow restriction therapy or Kinesio Taping?
No. Both are explicitly classified as experimental, investigational, or unproven under Aetna’s CPB 0325. Blood flow restriction (BFR) therapy and all forms of Kinesio Taping, McConnell Taping, and related taping protocols are excluded from coverage under current policy, regardless of diagnosis or clinical indication. Billing these services will result in automatic claim denial.
Q5: What modifier is required when a PTA provides physical therapy for Aetna patients?
When PT services are performed in part or in whole by a Physical Therapy Assistant, you must append modifier CQ to every applicable service code. As of December 1, 2023, Aetna reimburses PTA-delivered services at 85% of the allowed amount for the applicable CPT code. Failure to apply the CQ modifier correctly can result in either claim rejection or post-payment audit overpayment recovery.
Q6: How do I appeal a denied Aetna physical therapy claim?
File a reconsideration within 180 calendar days of the initial claim denial. Include medical records, progress notes, your written explanation of why the service meets Aetna’s medical necessity criteria under CPB 0325, and the original EOB. If the reconsideration is denied, file a formal appeal within 60 calendar days, with additional supporting documentation and peer-reviewed clinical evidence. Decisions on appeals are issued within 60 business days. For urgent situations, a physician can certify the need for an expedited review, which requires a decision within 72 hours.
Q7: Does Aetna cover physical therapy services delivered via telehealth?
Yes, for a defined subset of CPT codes with the appropriate GT or 95 modifier appended. Covered telehealth PT codes include 97110, 97112, 97116, 97161, 97162, 97530, 97537, 97760, and 97761, among others. Communication-based technology services including E-Visits (98970-98972), telephone assessments (98966-98968), and virtual check-ins are no longer covered by Aetna for PT services. Certain codes including 97129, 97130, 97150, 97163, 97164, and 97542 are also not covered when delivered via telehealth under current policy.
Conclusion: Maximizing Your Aetna Physical Therapy Reimbursements
Aetna physical therapy coverage is detailed, structured, and consistently applied — which means providers who invest the time to understand the policy will consistently outperform those who don’t. The rules are not designed to trap you; they are designed to ensure services are clinically justified, skillfully delivered, and properly documented.
Your action plan is straightforward:
- Memorize the covered CPT codes under CPB 0325 and verify plan-specific limits before every new Aetna patient begins treatment
- Build your documentation around Aetna’s five medical necessity criteria from day one, not after a denial
- Always append CQ for PTA-delivered services and GP for PT plan of care services
- Verify state-specific prior authorization requirements before starting treatment, even in states where PA was recently waived
- When you receive a denial, respond within 180 days with a structured reconsideration that directly cites CPB 0325 criteria
The providers who succeed with Aetna billing are not the ones who spend less time on documentation — they are the ones who build documentation systems that make compliance automatic. When your intake process, daily note templates, and billing workflows are all aligned with Aetna’s stated criteria, you will see your denial rate drop and your revenue cycle stabilize.
