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

Physical therapy treatment 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)
  

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

2. Payment may be made for up to 15 outpatient physical therapy sessions per calendar year (January-December).
3. Claims requesting outpatient physical therapy sessions in excess of 15 sessions are subject to review for the purpose of establishing medical necessity. Providers are required to submit the patient's treatment plan for review. Sessions in excess of 15 without an approved treatment plan will be denied as not medically necessary. A participating, preferred, or network provider cannot bill the member for the denied service. Additional supportive documentation from the provider requesting additional sessions could include the physician's pertinent evaluations (exam findings), progress notes, and opinions about the patient's need for continued therapy services. In addition, the medical history, as it relates to the outpatient physical therapy, must include the date of onset and/or exacerbation of the illness or injury. Any history of treatments from a previous provider is also necessary for patients who have transferred to a new provider for additional treatment. The limitation addressed in this paragraph does not apply to inpatient physical therapy services.
   

   
   

   NOTE:

   Under the UCR and Fee Schedule programs, inpatient physical therapy is covered. However, certain groups under indemnity programs have physical therapy coverage other than inpatient or may not pay for services provided by physical therapists. These situations are identified in the benefits schedule.

   
   

Procedure code 97112 representing therapeutic neuromuscular education is eligible for payment for the treatment of patients with cerebral palsy, head injury, cerebrovascular disease, spinal cord injury, and other neuromuscular disorders. The applicable diagnosis codes are: 332.0, 333.0, 340, 342.10-342.12, 343-343.9, 344.00-344.04, 356-356.8, 357-357.89, 358-358.9, 359-359.9, 434.01, 434.11, 436, 952-952.8. Diagnosis codes 356.9, 357.9, and 952.9 may be considered for coverage upon review of medical documentation that indicates the specific neuromuscular condition. In cases where none of these conditions are reported, this service is considered not medically necessary. A participating, preferred, or network provider cannot bill the member for services denied on the basis of medical necessity.

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 which 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 physician or therapist 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 which patients can be reasonably expected to accomplish through the aquatic therapy program and the specific methods chosen. Proper documentation includes:

• 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 which allows the patient's upper extremities to be submerged. Water depth should be at a level which 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.
  

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 which 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)
  

Procedure code 97116 should not be used to report orthotics or prosthetics training. Orthotics training should be reported using procedure code 97504. Prosthetics training should be reported using procedure code 97520.

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}
  

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

• Physical therapy evaluation and reevaluation (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 reeducation 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)
  

Separate payment may not be made for a physical therapy evaluation (97001-97002) or an athletic training evaluation (97005-97006), and another evaluation and management service on the same day by the same or an affiliated provider.

Muscle testing (95831-95834), range of motion testing (95851-95852), and physical performance testing (97750) are considered components of a physical therapy 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 therapy evaluation or athletic training service.

Maintenance Therapy

Physical therapy 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.

NOTE:

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

Physical therapy is covered whether provided by a doctor or a licensed physical therapist.

Managed Care

This medical policy applies to Managed Care programs except, points number 2 and 3 of the outpatient physical therapy guidelines section.

HMO and POS

For HMO and coordinated POS programs, outpatient physical therapy must be coordinated with the member's primary care physician. Therapy type and duration must be approved by the primary care physician and the Plan, prior to the member beginning outpatient physical therapy.

Please note that POS members may self-refer for outpatient physical therapy 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 therapy services.
