Physical medicine is a covered service when performed with the expectation of restoring the patient's level of function that has been lost or reduced by injury or illness.

This type of therapy should be provided in accordance with an ongoing, written treatment plan. The treatment plan should include:  

• the specific modalities/procedures to be used in treatment;
• the patient's diagnosis;
• degree of severity of the problem (mild, moderate, severe);
• impairment characteristics;
• physical examination findings - X-ray or other pertinent findings;
• specific statements of long- and short-term goals;
• a reasonable estimate of when the goals will be reached (estimated duration of treatment, e.g., number of weeks);
• the frequency of treatment (e.g., number of times per week); and,
• equipment and/or techniques utilized.

NOTE:

Treatment plan submission to Highmark is not required in order to receive reimbursement for physical medicine, aquatic therapy or gait training services. However, the treatment plans for these services should be maintained in the patient's medical record.          

The treatment plan should be updated as the patient's condition changes.  Treatment plans for physical medicine, aquatic therapy, and gait training must be maintained in the medical record.

A typical session usually consists of up to one hour of rehabilitative therapy or up to three physical medicine modalities/procedures performed on the same date of service.

Coverage for physical medicine is determined according to individual or group customer benefits.  Participating, preferred and network providers can bill the member for denied services that exceed the member's benefit limitations.

Outpatient physical medicine should be paid in accordance with the following guidelines:

Aquatic Therapy

Procedure code 97113 should be used to report aquatic therapy with therapeutic exercises. Aquatic therapy must be performed with the expectation of restoring a patient's level of function that has been lost or reduced by injury or illness. Aquatic therapy performed to maintain a level of function is considered to be a maintenance program. It is not eligible for payment.

A provider must have direct (one to one) patient contact when reporting aquatic therapy. Supervising multiple patients in a pool at one time and billing for each of these patients per 15 minutes of therapy time is not acceptable.

Before beginning an aquatic therapy program, the provider must prepare a treatment plan that includes short-term and long-term goals that the patient can be reasonably expected to accomplish through the aquatic therapy program and the specific methods chosen.  

Proper documentation should include:

• Documentation indicating whether the patient was in shallow or deep water. An aquatic therapy program undertaken for upper extremity exercises should take place in a depth of water that allows the patient's upper extremities to be submerged. Water depth should be at a level that provides the best postural position for exercise therapy.
• For resistance and strengthening exercises, the provider should document the number of repetitions, the number of sets, the type(s) of equipment, which body area(s) and the specific type(s) of exercise performed by the patient for each therapy session.

NOTE:

If a provider cannot substantiate increased resistance experienced as the patient

exercises in water, the session will be considered as endurance or conditioning
rather than progressive resistance exercises (PRE) to strengthen.

• Specific documented goals regarding decreasing inflammation, decreasing pain, increasing circulation, increasing strength, etc., and the means by which the specific goals will be achieved.
• Periodic re-evaluation documenting the number of times the patient has had rehabilitative aquatic therapy, the patient's pain level before beginning the program, the current pain level and future goals for the patient's care.
• Indication of pool water temperature for each session.

Procedure code 97113 represents aquatic therapy with therapeutic exercise.  Payment for procedure code 97113 includes whirlpool (97022) and/or Hubbard tank (97036). Separate payment will not be made for 97022 or 97036 in addition to 97113 for a single patient encounter.

Gait Training

Procedure code 97116 should be used to report gait training therapy. Gait training is a technique that restores a patient's normal stance, swing, speed, balance and sequence of muscle contractions for walking.

Generally accepted indications for gait training include:

• Foot drop resulting from stroke
• Herniated disc(s)
• Ankle, knee and/or hip replacement
• Traumatic amputations of the toe(s)

Documentation for gait training must demonstrate that the patient's gait was improved either by lengthening the gait or increasing the frequency of cadence lower-extremity.

Procedure code 97116 should not be used to report orthotics or prosthetics training. Orthotics training should be reported using procedure code 97760. Prosthetics training should be reported using procedure code 97761.

Vestibular Rehabilitation Therapy

Vestibular rehabilitation therapy generally refers to an individualized rehabilitation program for the treatment of patients with vertigo and disequilibrium. The therapy is designed to address the patient's specific complaints and functional deficits and may include specific exercises, gait training, balance retraining, and patient education and instructions for a home exercise program designed to decrease dizziness, improve balance function, and increase general activity levels. A vestibular rehabilitation program typically last 45 minutes per session and is prescribed 1-2 times per week. In general, patients remain in the program 4-8 weeks.

A vestibular rehabilitation program may be considered medically necessary for patients with vertigo, disequilibrium, and balance deficits related to the following conditions:

• peripheral vestibular disorders {e.g., labyrinthitis (386.30-386.35), neuritis (386.12), benign paroxysmal positional vertigo (386.11), post vestibular surgical symptoms, and bilateral vestibular loss},
• mixed {peripheral (386.10-386.19) and central (386.2)} vestibular disorders, and
• central causes of vertigo {e.g., CVA (436), multiple sclerosis (340), and mild traumatic brain injury}

If none of these conditions are reported, a vestibular rehabilitation program is considered not medically necessary, and therefore, not covered. A participating, preferred, or network provider cannot bill the member for the denied services.

A vestibular rehabilitation program may include the following physical medicine modalities:

• Physical medicine evaluation and re-evaluation (97001, 97002),
• Therapeutic procedure, one or more areas, each 15 minutes; therapeutic exercises to develop strength and endurance, range of motion and flexibility (97110),
• Neuromuscular re-education of movement, balance, coordination, kinesthetic sense, posture, and proprioception (97112),
• Gait training (includes stair climbing) (97116), and
• Therapeutic activities, direct (one on one) patient contact by the provider (use of dynamic activities to improve functional performance) (97530)

Dry Hydro Massage (97799)

Hydrotherapy refers to the use of water in the treatment of disease or trauma.  The patient lies back, completely clothed, on the surface of a hydrotherapy table.  Under the surface is a mattress filled with heated water.  A pump propels the water toward the patient through hydro-jets.  The pressure of the water against the patient’s body provides the massage.  A primary wave and a lighter secondary wave combine to produce a deep tissue massage to all areas of the spine simultaneously.  The therapy can be applied to nearly every body part by changing the individual’s position on the table.  This is unattended hands-free massage.

Dry hydro massage is considered not medically necessary.  A participating, preferred, or network provider cannot bill the member for the denied service.

The Profiler and Aqua PT are considered forms of dry hydro massage.

Equestrian/Hippotherapy (S8940)

Date Last Reviewed - 01/2005

Hippotherapy (Equestrian therapy) is a treatment modality that utilizes the movement of a horse as a tool to improve the patient’s neuromuscular function.   Hippotherapy is used for patients with compromised neuromuscular function, e.g., cerebral palsy.  The horse’s walk provides sensory stimulation through its rhythmic, repetitive movement.  The goals of hippotherapy are to combine this treatment modality with other therapeutic modalities to improve balance, posture , mobility and function.

Hippotherapy is considered experimental/investigational.  Scientific evidence does not demonstrate the efficacy of this service.  A participating, preferred, or network provider can bill the member for the denied service.

Low-Level Laser Therapy (S8948) (Cold Laser Therapy)

Date Last Reviewed - 11/2005

Low-level laser therapy is the non-invasive application of red or cold (subthermal) laser light to injuries or wounds to improve soft tissue healing and relieve both acute and chronic pain (e.g., wound healing, carpal tunnel syndrome, and pain management).

Low-level laser therapy is considered experimental/investigational.  This service is still being performed in a clinical trial setting with no long-term outcomes available.  Further studies are needed to determine the long-term efficacy of this modality.  A participating, preferred, or network provider can bill the member for the denied service. 

Physical Medicine or Athletic Training Evaluation

An evaluation and management (E&M) service is considered an inherent part of a physical medicine evaluation (97001-97002) or athletic training evaluation (97005-97006).  The E&M service is not eligible for separate payment when reported on the same day as a physical medicine evaluation or athletic training evaluation.

Consequently, when an evaluation and management service is reported in conjunction with a physical medicine evaluation or athletic training evaluation, the services should be combined under the appropriate code for the physical medicine evaluation or athletic training evaluation. A participating, preferred, or network provider cannot bill the member for the E&M service.

Muscle testing (95831-95834), range of motion testing (95851-95852), and physical performance testing (97750) are considered components of a physical medicine evaluation (97001-97002) or an athletic training evaluation (97005-97006), and are not eligible for separate payment when billed on the same day as a physical medicine evaluation or athletic training service.

Maintenance Therapy

Physical medicine performed repetitively to maintain a level of function is not eligible for payment. A participating, preferred, or network provider can bill the member for the denied service. A maintenance program consists of activities that preserve the patient's present level of function and prevent regression of that function. Maintenance begins when the therapeutic goals of a treatment plan have been achieved, or when no additional functional progress is apparent or expected to occur. Maintenance therapy should be reported under procedure code S8990.

NOTE:

For information on cognitive rehabilitation and sensory integration techniques, refer to Medical Policy Bulletin Y-2.

For information on interferential stimulation, refer to Medical Policy Bulletin E-45.

Under the Federal Employee Program, all services that utilize FDA-approved drugs, devices, or biological products are eligible when intended for the treatment of a serious or life-threatening condition and when medically necessary and appropriate for the patient’s condition. Low level laser therapy (S8948) is considered an eligible service for treatment of carpel tunnel syndrome (354.0) when determined medically necessary based on the patient’s condition.

Please note that POS members may self-refer for outpatient PM&R services.

When the member meets the medical necessity criteria detailed in this medical policy, please refer to the member's specific benefits schedule to determine and approve the duration of outpatient physical medicine services.
