Bennett's fracture, right hand, sequela

This code signifies a Bennett's fracture of the right hand, specifically indicating a sequela. A Bennett's fracture is an intra-articular fracture of the base of the first metacarpal bone, extending into the carpometacarpal (CMC) joint. The "sequela" designation means this code is used for conditions that are residual effects or complications of the original fracture, even after the acute phase of healing has passed.

Use this code when documenting chronic pain, deformity, arthritis, nonunion, malunion, or restricted range of motion in the right thumb CMC joint that is directly attributable to a previously sustained Bennett's fracture. This applies to encounters where the patient is being treated for the long-term consequences, not the initial injury or its immediate healing.

• Always sequence the sequela code first, followed by codes for the specific residual condition (e.g., M18.0 for primary osteoarthritis of the first carpometacarpal joint).
• Ensure documentation clearly links the current condition to the prior Bennett's fracture of the right hand.
• Do not use this code for initial treatment or routine follow-up during the acute or subacute healing phase of the fracture.
