Contracture of muscle, left upper arm

This code signifies a persistent shortening and hardening of muscle tissue in the patient's left upper arm, leading to a restriction in the range of motion of the affected joint. This contracture can result from various etiologies, including trauma, neurological conditions, or prolonged immobility.

Apply this code when documentation explicitly states a muscle contracture affecting the left upper arm. This is appropriate for conditions such as Volkmann's contracture of the left upper arm, or post-traumatic muscle shortening in this specific anatomical location. Supporting documentation should clearly identify the affected limb and the nature of the muscle involvement.

• Ensure laterality is accurately documented; distinguish between left, right, and bilateral contractures.
• Do not confuse with muscle spasm or cramp, which are transient conditions.
• Consider an additional code for the underlying cause of the contracture if known and documented.
