Aetna Occupational Therapy coverage criteria

Aetna covers short-term occupational therapy as medically necessary when a physician prescribes it and there is a reasonable expectation of significant, measurable functional improvement (or it establishes a safe self-maintenance program) within a predictable timeframe, delivered by a licensed OT provider under a written, physician-approved plan of care. The key gate is documented, measurable improvement: once the member plateaus, can be maintained without skilled therapy, or shows no progress, continued OT is not covered, and maintenance care, non-skilled services, IADLs (e.g., driving, home/leisure management), and educational-setting OT are excluded.

Path
Aetna covers short-term occupational therapy as medically necessary when a physician prescribes it and there is a reasonable expectation of significant, measurable functional improvement (or it establishes a safe self-maintenance program) within a predictable timeframe, delivered by a licensed OT provider under a written, physician-approved plan of care. The key gate is documented, measurable improvement: once the member plateaus, can be maintained without skilled therapy, or shows no progress, continued OT is not covered, and maintenance care, non-skilled services, IADLs (e.g., driving, home/leisure management), and educational-setting OT are excluded. Coverage criteria include: Aetna considers short-term occupational therapy (OT) medically necessary in selected cases when prescribed by a physician AND ALL of the following criteria are met (purpose, condition-improvement, service-delivery, and plan-of-care requirements below); Purpose (ONE of): (a) to learn or re-learn daily living skills (e.g., bathing, dressing, eating) or compensatory techniques to improve the level of independence in activities of daily living; OR (b) to provide task-oriented therapeutic activities designed to significantly improve, develop, or restore physical functions lost or impaired as a result of a disease or injury; Condition-improvement requirement (ONE of): the member's physician or licensed health care practitioner determines that the member's condition can improve significantly (based on objective measures) within 1 month of the therapy start date; OR the therapy services are necessary for the establishment of a safe and effective maintenance program to be performed by the member without ongoing skilled therapy services. The services must be for the treatment of a specific illness or injury; Service delivery (must meet ALL): OT services are intended only for episodes where there is a reasonable expectation of significant improvement within a reasonable and predictable period of time; AND services are performed by a duly licensed and (if applicable) certified OT provider; AND services are within the applicable scope of practice in the jurisdiction where licensed; AND services are of a complexity and nature that require a licensed professional therapist or a supervised licensed ancillary person as permitted by state law; OT may be provided by physicians or by personnel under a physician's direct supervision as permitted by state law (note: physicians cannot directly supervise occupational therapy assistants); Plan of care (must meet ALL): services are provided according to an ongoing, written plan of care that is reviewed and approved by the treating physician as required by state law and regulations; AND the plan of care contains sufficient detail with appropriate objective and subjective data to demonstrate medical necessity (see Appendix documentation requirements); OT is medically necessary only if there is a reasonable expectation that OT will achieve measurable improvement in the member's condition in a reasonable and generally predictable period of time; Home-based OT is considered medically necessary in selected cases based on the member's needs, provided the member is homebound; it is typically used during a transition from a hospital setting to home as an extension of case management services; Note (HMO/QPOS plans): home-based OT accumulates toward the 60-day limit or other applicable rehabilitation benefit limits. Applies to 6 codes: 97140, 97165, 97166, 97167, 97168, 97535.
Action
Confirm prior-authorization status with Aetna before scheduling — it is code- and plan-specific, and this policy is not an exact authorization source. Documentation: An ongoing, written plan of care that documents medical necessity, is specific to the diagnosis/presenting symptoms/evaluation findings, is signed by the member's occupational therapist, and contains sufficient information to determine medical necessity; Plan of care must include a reasonable estimate of when the goals will be reached; Plan of care must include quantitative objectives; Plan of care must include specific statements of long-term and short-term goals; Plan of care must include the date of onset (or exacerbation) of the disorder/diagnosis; Plan of care must include the frequency and duration of treatment; Plan of care must include the specific treatment techniques and/or exercises to be used; The plan of care must be updated as the member's condition changes; Documentation that treatment demonstrates a reasonable expectation of improvement; The member must be re-evaluated regularly (at least monthly); Documentation of progress toward therapy goals, with treatment goals/results specifically demonstrating that OT is contributing to improvement; Documentation that services are of a complexity and nature requiring a licensed professional therapist (or supervised licensed ancillary person) as permitted by state law.
Trap
Policy exclusions and limitations: Continuing supervised OT is NOT medically necessary once the maximal therapeutic benefit has been achieved OR once a maintenance/home program is feasible to transition the member to; OT in persons whose condition is neither regressing nor improving is NOT medically necessary; OT in asymptomatic persons, or in persons without an identifiable clinical condition, is NOT medically necessary; Educational training or services are excluded; OT is not covered when provided in educational settings under plans that contain the educational exclusion; Driver training is not covered: it is not considered treatment of a disease because driving is not a basic activity of daily living; Continuation of OT is NOT medically necessary when OT has not resulted in meaningful progress in ADL/function, as evidenced by a lack of change with the current type/frequency of therapy; Continuation of OT is NOT medically necessary when the therapy is part of a maintenance program that can be provided by a caregiver without a therapist; Continuation of OT is NOT medically necessary when, if prescribed for pain, the member does not have pain reduction beyond the duration of the therapy session; Continuation of OT is NOT medically necessary upon continued lack of individual participation in the care plan; Non-skilled service NOT medically necessary: passive range of motion (PROM) that is not specifically a part of a restorative program for functional loss; Non-skilled service NOT medically necessary: services that maintain function by using routine, repetitive and reinforced procedures after the point of initial patient teaching; Non-skilled service NOT medically necessary: general conditioning, or recovery from an acute medical/surgical illness that caused deconditioning; Non-skilled service NOT medically necessary: services that can be safely and effectively furnished by non-skilled personnel; Maintenance care is NOT medically necessary: activities intended to preserve current function or prevent regression; maintenance begins when therapeutic goals are achieved OR when no further significant progress is made or can reasonably be anticipated; Maintenance care NOT medically necessary: continued activities for patients who have achieved generally accepted function/muscle strength at a plateau or at 'normal' levels (a plateau is generally a period of four weeks, or a lesser period generally accepted depending on the specific condition/patient situation); Instrumental Activities of Daily Living (IADL) are NOT covered: community living skills (e.g., balancing a checkbook, use of public transportation); IADL NOT covered: home management skills (e.g., meal preparation, laundry); IADL NOT covered: leisure activities (e.g., hobbies, sports, recreation) even if part of the OT treatment plan; IADL NOT covered: motor vehicle driving evaluations and driving instruction, including automobiles, trucks, motorcycles, and bicycles; IADL NOT covered: personal safety preparedness; In plans that exclude developmental delay, OT is not covered for the following diagnoses: intellectual disabilities (F70-F79); pervasive and specific developmental disorders (F80.0-F84.9); ADHD, other type (F90.8); other and unspecified lack of coordination (R27.0-R27.9); unspecified speech disturbances (R47.9); dyslexia and alexia (R48.0); lack of expected normal physiological development in childhood (R62.0-R62.59); Benefit limit (many HMO plans): OT benefit is limited to a 60-day treatment period per specific condition; once the 60-day period expires, no additional OT benefits are provided for that condition during the contract year. Multiple 60-day courses per year are allowed only for separate conditions (e.g., a new surgical procedure initiates a new condition); an exacerbation/flare-up of a chronic illness is NOT considered a new incident. Claims may be denied when the requested service falls under these. Some of these are conditional (note the stated exceptions) — confirm specifics against the bulletin.
