Flexion deformity, unspecified wrist

This diagnosis code signifies a permanent bending or contracture of the wrist joint, where the hand is abnormally flexed towards the forearm. It indicates a limitation in the wrist's range of motion, specifically in extension, without further specification of the affected side.

Apply this code when documentation clearly states a flexion deformity of the wrist, and the laterality (left or right) is not specified. This is appropriate for conditions like post-traumatic contractures, congenital deformities, or neurological conditions leading to wrist flexion, where the specific side is unknown or not documented.

• Avoid using this code if the documentation specifies laterality (e.g., left or right wrist); instead, use the more specific M21.231 or M21.232.
• Ensure the medical record supports a deformity (a fixed or permanent condition), not just temporary flexion due to muscle spasm or positioning.
• Consider sequencing this code after any underlying cause or primary diagnosis contributing to the flexion deformity.
