Medical Policy: 01.01.04 
Original Effective Date: December 1993 
Reviewed: October 2014 
Revised: October 2014 


Benefit Application
Benefit determinations are based on the applicable contract language in effect at the time the services were rendered. Exclusions, limitations or exceptions may apply. Benefits may vary based on contract, and individual member benefits must be verified. Wellmark determines medical necessity only if the benefit exists and no contract exclusions are applicable. This medical policy may not apply to FEP. Benefits are determined by the Federal Employee Program.

This Medical Policy document describes the status of medical technology at the time the document was developed. Since that time, new technology may have emerged or new medical literature may have been published. This Medical Policy will be reviewed regularly and be updated as scientific and medical literature becomes available.


Description: 

Continuous passive motion (CPM) device is a treatment modality designed to facilitate recovery following injury to or surgery on joint(s) or peri-articular tissues, including cartilage, tendons, and ligaments. CPM provides motion of joint at a consistent speed without patient assistance, using a motorized device that moves the affected joint through a prescribed arc of motion (flexion/extension). CPM devices are frequently applied in the immediate postoperative period and may be continued at home for a variable period of time. 

 

Physical therapy of joints following surgery focuses on passive motion to restore mobility and active exercises to restore strength. While passive motion can be administered by a physical therapist, CPM devices have also been used. CPM is thought to improve recovery by stimulating the healing of articular tissues and circulation of synovial fluid; reducing local edema; and preventing joint stiffness or contractures, adhesions, or cartilage degeneration. Therefore, potential benefits of CPM may include short-term ROM gains, decreased development of DVT, decreased hospital length of stay, reduced cost compared with physical therapy (PT) alone and reduced postoperative use of analgesics.

 

Based on the peer reviewed literature most of the research on continuous passive motion (CPM) devices has been as a postoperative treatment for total knee arthroplasty (TKA) and ligamentous or cartilage repair of the knee. Studies conducted in a controlled hospital setting suggest that CPM can improve rehabilitation when postoperative mobility is restricted. However, current postoperative rehabilitation protocols are considerably different than when the largest body of evidence was collected, making it difficult to apply available evidence to the present situation. Recent literature suggests that institutional and home use of CPM has minimal benefit when combined with standard physical therapy after total knee arthroplasty (TKA). For patients who are unable to participate in standard physical therapy regimens, CPM remains an alternative physical therapy modality. Therefore, the use of CPM in the home setting may be considered medically necessary after TKA as an adjunct to physical therapy under conditions of low postoperative mobility or inability to comply with rehabilitation exercises, this may include patients with complex regional pain syndrome (reflex sympathetic dystrophy); extensive arthrofibrosis or tendon fibrosis; or physical, mental or behavioral inability to participate in active physical therapy. CPM may also be considered medically necessary for patients in the non-weight bearing period following intra-articular cartilage repair procedures of the knee.

        

For joints other than the knee, there has been interest in the use of CPM in other weight bearing joints such as hip, ankle and metatarsals and non-weight bearing joints including the shoulder, elbow, metacarpals and interphalangeal joints. The use of CPM is also being explored in stroke and burn patients. Based on the available published peer reviewed literature, the literature does not support the use of CPM postoperatively as adjunct to physical therapy for any joint other than the knee. Therefore, the use of CPM for joints other than the knee has not been medically proven to be effective in improving health outcomes and is considered not medically necessary.

Policy: 

Continuous Passive Motion devices (CPM) in the home setting may be considered medically necessary in the following situations, when the device is initiated within the 48-hour period following surgery:

  • Total Knee Arthroplasty (TKA)
  • Open reduction and internal fixation of tibial plateau or distal femur fractures involving the knee joint
  • Knee arthrofibrosis occurring after Total Knee Arthroplasty (TKA) and requiring manipulation under general anesthesia.
  • Post operative rehabilitation after ACL reconstruction

Continuous Passive Motion devices (CPM) may be considered medically necessary during the non-weight bearing rehabilitation period following intra-articular cartilage repair procedures of the knee:

  • Microfracture; or
  • osteochondral grafting; or
  • autologous chondrocyte implantation; or
  • treatment of osteochondritis dissecans; or
  • repair of tibial plateau fractures

Note:  If the CPM device is determined to be medically necessary, the CPM is payable only as rental equipment for 30 days following surgery.

 
The use of CPM in the home setting is considered not medically necessary for all other conditions including but not limited to the following circumstances:

  • Treatment of acute or chronic low back pain
  • For any joint other than the knee
  • For any condition of the knee other than those described above
