In simple words: This is a device worn on the forearm to help improve its ability to rotate. It applies a gentle, continuous stretch to help regain movement after injury or surgery. Some versions of this device can also provide short bursts of more intense stretching.

This code represents a static progressive stretch forearm device designed for pronation or supination exercises, which may include a range of motion adjustment feature. It encompasses all necessary components and accessories for the device's function. The device is used to apply a low-force stretch over time, aiding in the recovery of forearm range of motion often impaired due to muscle contracture after trauma, illness, or surgery. The range of motion adjustment, when present, facilitates brief periods of high-intensity stretch interspersed with relaxation, addressing periarticular fibrosis and limited joint motion.

Example 1: A patient post-wrist fracture experiences limited pronation and supination. Code E1818 is used for the static progressive stretch device to improve forearm mobility., Following elbow surgery, a patient develops periarticular fibrosis. E1818 is applied for the device with range of motion adjustment to address joint stiffness and restore range of motion., A patient with a neurological condition experiences muscle contracture limiting forearm movement. E1818 is utilized for the device to provide a continuous stretch and prevent further loss of mobility.

Documentation should include the medical necessity for the device, such as diagnosis, prior treatment, and expected functional improvement. Details regarding the specific device features (pronation/supination, range of motion adjustment) should also be documented.
