Contracture of muscle, unspecified forearm

This code signifies an abnormal and persistent shortening of the muscle tissue in an unspecified forearm, leading to a restriction in the range of motion of the affected joint. This contracture can result from various underlying conditions, including trauma, neurological disorders, or prolonged immobilization.

Apply this code when documentation clearly indicates a muscle contracture affecting the forearm, but the specific muscle involved is not identified. This code is appropriate when the laterality (right or left) of the forearm is also not specified in the medical record.

• Ensure documentation specifies "unspecified forearm" and does not identify a particular muscle or laterality.
• If the specific muscle or laterality is known, use a more precise code from the M62.4- series (e.g., M62.431 for right forearm, M62.432 for left forearm).
• Always sequence this code after any underlying cause of the contracture, if applicable (e.g., stroke, cerebral palsy).
