Coverage Criteria for Physical Therapy and Medical Massage

inv-01: Medical Necessity — Covered when ALL of the following are met

Covered when ALL of the following are met

General medical necessity for PM&R-PT and medical massage: The individual has a documented condition causing physical functional impairment or disability that interferes with activities of daily living (ADLs); AND there is a reasonable expectation of measurable improvement in a reasonable and predictable period of time based on diagnosis‑related treatment/therapy goals; AND due to the individual's physical condition the complexity and sophistication of therapy and therapeutic modalities require the judgment, knowledge, and skills of a qualified PM&R‑PT or medical massage provider (a provider licensed where required and performing within scope); AND PM&R‑PT and/or medical massage services provide specific, effective, and reasonable treatment consistent with a detailed plan of care using objective measurements and standardized tests for strength, range of motion, functional levels and pain.

Chronic disease-specific criteria: For chronic diseases or conditions that have lasted at least 3 months or are slowly progressive (e.g., cancer with active treatment, lymphedema, MS, Parkinson's, other chronic degenerative or inherited musculoskeletal disorders), the skilled services of a qualified provider are required to provide reasonable and necessary corrective or rehabilitative care to prevent or slow further deterioration; AND a documented plan of care is established based on evaluation findings and directed toward improving impairments and functional deficits, including therapeutic treatment to reduce/manage symptoms, a specifically prescribed, directed and monitored home/self‑exercise program with documentation of compliance, and progress reports with objective measurements that justify continued treatment.

Medical massage-specific criterion: Medical massage may be considered medically necessary as the sole therapeutic intervention when ALL general PM&R‑PT criteria are met AND a diagnosis‑specific prescription from the attending clinician with prescribing authority, stating the number of medical massage visits, is retained in the member's massage therapy medical record.

Home-based therapy: Home‑based physical therapy, including medical massage, may be covered when the individual is homebound and all other applicable medical necessity criteria in this policy are met.

Plan of care requirements: A plan of care (POC) must be established prior to the start of treatment and include specific long‑ and short‑term measurable goals, measurable objectives, a reasonable estimate of time to reach goals, and the specific treatment techniques/exercises to be used; the POC must be updated as the individual's condition changes and recertified by the referring licensed healthcare provider at least every 60 days.

inv-02: Medically Necessary Physical Therapy (Part A/Part B) — skilled PT services include those ordered by a physician under home health (Part A) or outpatient (Part B)

Medically necessary skilled physical therapy services include those ordered by a physician under home health (Part A) or outpatient (Part B) when intended to improve, maintain, or prevent deterioration of function.

Skilled PT necessity: Services must be ordered by a physician (Part A for home health; Part B for outpatient) and are considered skilled therapy when they are intended to: improve the individual's current condition; maintain the individual's current condition; or prevent or slow further deterioration of the individual's condition.

inv-03: Physical Therapy — Medical Necessity — Covered when ordered by an appropriate prescriber and when medically necessary to improve, maintain, or prevent deterioration of function

Covered when ordered by an appropriate prescriber and when medically necessary to improve, maintain, or prevent deterioration of function:

Physical therapy coverage criteria: Services are ordered by a physician (outpatient) or by a physician under home health if the individual is homebound; services must be medically necessary and may be provided to improve the individual's current condition, maintain the individual's current condition, or prevent/slow further deterioration of the individual's condition.

Rehabilitation therapy for pes planus (flat feet) is excluded from coverage except when it is part of the recovery following corrective surgery for flat feet. Maintenance therapy programs—defined as services that preserve an individual’s present level of function and prevent regression rather than provide corrective benefit—are not covered once therapeutic goals have been achieved or when no further functional progress is expected. Examples include ongoing PM&R-PT or medical massage after maximum improvement is reached, services that merely enhance performance beyond routine functional tasks, passive stretching performed by non‑skilled personnel, and general home exercise programs that are not focused on identified impairments or functional limitations. The plan of care must be established before treatment and include specific long‑ and short‑term measurable goals, the techniques/exercises to be used, an estimated timeframe to reach goals, and be recertified by the referring licensed provider at least every 60 days.

Therapy services provided by athletic trainers and other providers who are not recognized under the member’s health benefit plan are not covered. Verify whether a provider meets the plan’s definition of a qualified provider by checking the member’s benefit booklet or contacting Customer Service prior to billing or scheduling services.

Consistent with Medicare policy, medical massage therapy is not covered by Medicare. Providers should confirm members’ coverage and any plan‑specific limitations prior to rendering services.

Duplicate therapy—where physical therapy, occupational therapy, and/or medical massage provide the same treatment for the same diagnosis—is considered not medically necessary and may be denied unless there are separate, distinct functional goals for different diagnoses. Similarly, maintenance therapy programs intended only to preserve current function without expectation of further corrective benefit are not medically necessary. Denials may occur when documentation does not show objective progress toward measurable goals, or when services continue after the individual has reached maximum therapeutic improvement.

Provider Requirements, Documentation, and Billing Actions

Prior Authorization

Medical necessity review / visit limits

In some member contracts, physical medicine rehabilitation-physical therapy and medical massage therapy are subject to a medical necessity review by eviCore Healthcare and/or other delegated review organizations. Benefits for therapy services in certain plans may include a fixed number of treatment visits per year; when the maximum number of covered visits is reached, coverage will stop. Providers should verify prior authorization requirements and visit limits with the member's benefit booklet or by contacting Customer Service before initiating treatment.

Some plans require medical necessity review by eviCore based on evidence-based clinical guidelines
Fixed annual visit limits may apply; coverage stops when the maximum is reached
Contact Customer Service or check the member's contract to verify prior authorization and benefit limits

Denial Risk

Denial triggers

Duplicate therapy (services that provide the same treatment for the same diagnosis when provided concurrently by PT, OT, and/or medical massage therapy) is considered not medically necessary. Maintenance therapy programs — ongoing services intended only to preserve current function after therapeutic goals have been met or when no further functional progress is expected — are not covered. Non-skilled services that do not require the skills of a qualified PM&R-PT or medical massage provider are not covered. Therapy services provided by providers not recognized by the Health Plan (for example, athletic trainers when not included in the member contract) may be denied.

Duplicate therapy (same treatment for same diagnosis across PT/OT/massage) — denial trigger
Maintenance therapy programs — denial trigger
Non-skilled services and services by non-recognized providers (unless covered in the member contract) — denial trigger

Documentation Required

Required documentation elements

Documentation must clearly support the medical necessity of the rehabilitation therapy provided. The plan of care must be established prior to the start of treatment and updated/recertified as the individual's condition changes (at least every 60 days when applicable). Records must be legible, dated, and authenticated by the performing clinician where required.

Initial and follow-up visit notes must document clinical impression, diagnosis, and treatment plan that support medical necessity
Plan of care must include long- and short-term measurable goals, frequency and duration of planned treatment, specific treatment techniques/exercises, and estimated completion date
Plan of care must be recertified by the referring licensed healthcare provider at least every 60 days and updated as condition changes
Documentation must be legible, include a key for any abbreviations/symbols, and include initials of all providers and staff delivering care

Documentation Required

Documentation and authentication

Objective findings and progress must be documented at each visit. Re-evaluations at follow-up visits must include objective physical findings, the individual's subjective response to treatment, measured clinical/functional improvement, review of progress toward goals, updates to the plan of care, and communication of outcomes and recommendations to the referring clinician with prescribing authority when applicable.

Objective findings: patient complaint, signs/symptoms of impairment, ADL impact
Re-evaluation at follow-up: objective status, subjective response, measured improvement, plan review and updates, reporting to referring clinician

Definitions

Homebound / confined to home definition

Allowed exceptionsMember may leave home for medical treatment such as chemotherapy and such outings do not negate homebound status.

Not determined byHomebound status is not determined by lack of transportation or inability to drive.

Maintenance therapy program — definition

Typical contextMay apply to individuals with chronic and stable conditions where skilled supervision is no longer required.

Coverage stanceContinuation of PM&R-PT and/or medical massage services solely to maintain function is not covered.

Non-skilled services — definition

DefinitionNon-skilled services are activities that maintain function and could be done safely and effectively by the individual or a non-medical person without the skills or supervision of a qualified provider.

ExamplesSelf-performed aerobic warm-up (treadmill, stationary bike), self-applied modalities, passive range-of-motion not related to restoring specific loss of function, unskilled repeated procedures that reinforce previously learned skills.

ImplicationNon-skilled services are not considered skilled PM&R-PT or medical massage and are excluded from coverage when intended only to maintain function.

Qualified provider — definition and examples; therapy services not covered when outside scope

Coverage exclusionTherapy services provided by providers not recognized by the Health Plan (for example, athletic trainers) will not be covered.

DocumentationFollow APTA guidance for patient/client management and document examination, evaluation, diagnosis, prognosis, and interventions performed by the PT or PTA as permitted by law.

Clinical practice guideline (example) — AOPT/AASPT guideline reference example

Example guidelineAOPT/AASPT clinical practice guidelines provide evidence-based recommendations; example: the rotator cuff tendinopathy guideline emphasizes exercise-based management, discourages routine early imaging, and supports therapeutic exercise and functional rehabilitation strategies.

PurposeGuidelines are based on systematic reviews, include evidence ratings, and follow rigorous development protocols to inform diagnosis, nonsurgical care, and rehabilitation.

Source recommendationUse AOPT/AASPT guidelines to guide conservative, exercise-based management and rehabilitation planning.
