Coverage Criteria

General medical necessity

Physical therapy/medicine services are medically necessary when ALL of the following criteria are met.

General medical necessity requirements

Qualified, constantly attended service: The service requires constant attendance by a licensed physical therapist, physical therapy assistant, medical doctor, doctor of osteopathy, doctor of chiropractic, athletic trainer, podiatrist, advanced practice registered nurse, or doctor of naturopathy; is delivered by a provider licensed in the state where services are performed and practicing within the scope of that license; and requires the judgment, knowledge, and skills of a qualified provider because of the treatment complexity and the patient’s physical condition.Constant attendance
Specific goal and expected improvement: The service achieves a specific diagnosis-related goal for a patient with a reasonable expectation of measurable improvement within a reasonable and predictable period.Measurable improvement within a reasonable and predictable period
Appropriate treatment: The treatment is specific, effective, and reasonable for the patient’s diagnosis and physical condition.
Ongoing progress: For ongoing services, there is clear, measurable progress toward a rehabilitative goal, a less restrictive setting, or another medically necessary goal.Clear, measurable progress
Aqua and pool therapy meets all of the same medical-necessity criteria described above.

Physical therapy for autism spectrum disorder

Physical, occupational, and/or speech therapy for autism spectrum disorder may be medically necessary when ALL of the following criteria are met.

ASD therapy requirements

Qualifying diagnosis
- The individual has a documented Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), diagnosis of autism spectrum disorder.
- The individual has moderate to severe intellectual disability.
Clinically significant functional impairment
- Qualifying impairment
  - The individual has impaired motor skills and/or musculoskeletal system involvement.

Medically necessary physical therapy services

Covered when all applicable requirements are met.

Medical necessity and benefit eligibility

Medical necessity and contract eligibility: Services are medically necessary, meet the applicable policy guidelines, and are eligible under the member’s contract or benefit plan.
Member benefit language, contract limitations, and employer plan requirements take precedence over conflicting policy language.
Evaluation before treatment: A physical therapy/medicine evaluation is completed before treatment to establish medical necessity, gather baseline data, establish a treatment plan, and develop goals.Before implementing treatment
Plan of care: The plan of care documents the prior functional level when applicable; objective, measurable, functional deficits using comparable and consistent methods; specific short- and long-term goals; measurable objectives; a reasonable goal-reach timeframe and rehabilitation prognosis; treatment techniques or activities; frequency and duration of treatment; and a discharge plan initiated at the start of treatment.

Billing and documentation compliance

Billing and documentation criteria.

Session and timed-service requirements

Complete treatment documentation: The medical record documents treatment duration, modality parameters, settings, total treatment time, progression and improvement of exercises, and whether the provider was in constant attendance or provided one-on-one treatment. The documentation supports the procedure codes billed and the medical necessity of the procedures performed.
Constant-attendance services: For constant-attendance procedures or modalities, treatment time is documented in minutes and units are assigned according to the policy time ranges.8–22 minutes = 1 unit; 23–37 minutes = 2 units; 38–52 minutes = 3 units; 53–67 minutes = 4 units
For less than 8 minutes, use modifier 52 for reduced services.
Session maximum: Billing does not exceed four units of physical therapy services, including treatment and/or evaluation, per session.

Services are not medically necessary when they consist of repetitive exercises intended only to improve walking or running distance, strength, or endurance, or passive range of motion that is not restoring a specific loss of function. Preventive or maintenance activities, general conditioning, self-monitored repetitive exercise or equipment, athletic conditioning, and treatment provided after therapeutic goals have been achieved with no further progress apparent or expected are also excluded. Modalities not listed in Attachment I and inpatient admission solely for physical therapy/medicine are not medically necessary.

The benefit excludes programs intended to establish or re-establish occupational, hobby, sport, or leisure capabilities. Acupuncture, acupressure, massage, hypnotherapy, rolfing, homeopathic remedies, and most naturopathic remedies are excluded, subject to the policy’s stated naturopathic exception. Other exclusions include biofeedback or self-care training, cognitive or educational programs, group therapy or exercise, custodial care, developmental-delay treatment except as addressed by the Applied Behavior Analysis policy, work-hardening programs and applicable workers’ compensation conditions, support therapies, and fitness equipment, braces, devices, weight-loss programs, or memberships primarily used for sports, recreation, or fitness.

Services must be performed within the rendering provider’s license and certification and within the scope of practice. Services or modalities that do not require constant provider attendance, including unattended hot or cold packs, electrical stimulation, paraffin baths, whirlpools, diathermy, infrared, and ultraviolet treatment, are excluded. Non-skilled supervised services, services beyond those needed to restore activities of daily living, and supplying or dispensing medical supplies or durable medical equipment are also excluded; physical therapy providers may prescribe DME.

Wellness or preventive physical therapy/medicine services are excluded, as is care designed to prepare a member for specific occupational, leisure, recreational, hobby, or sports activities. Acupuncture and massage therapy are identified as excluded or non-covered examples. When a member elects to receive services beyond coverage limitations or excluded services, including wellness or sports-related services, a self-pay agreement must be completed before services are rendered and maintained in the medical record.

Supplying or dispensing medical supplies or durable medical equipment is excluded when the provider contract excludes those services. Provider contract terms must therefore be reviewed before billing or furnishing covered supplies or DME.

The policy identifies biofeedback, passive or unattended modalities, massage, group therapy, athletic-training services, community/work integration, work hardening or conditioning, specified unattended electrical stimulation, maintenance therapy, and hippotherapy as contract exclusions or not-covered services. The listed services and modalities are not covered even when billed under the corresponding procedure codes.

Services that do not satisfy the stated medical-necessity requirements are not medically necessary. This includes services without a specific diagnosis-related goal, a reasonable expectation of measurable improvement, an effective and appropriate treatment, a qualified provider, the required provider skill, or clear measurable ongoing progress. Services may also be denied when treatment goals have been achieved and no further progress is apparent or expected.

Repetitive, preventive, maintenance, conditioning, behavioral, or intellectual-disability treatments are not medically necessary when they do not require qualified provider skills or do not restore a specific lost function. Non-restorative passive treatments and self-monitored exercises or equipment are likewise excluded when they do not address restoration of a specific loss of function.

The unlisted codes 97039 for an unlisted modality and 97139 for an unlisted therapeutic procedure are identified as not medically necessary. Code 97039 requires the modality type and time to be specified when constant attendance applies; code 97139 requires the procedure to be specified.
