Sublux of unsp interphaln joint of r mid finger, sequela

This code signifies a chronic or residual subluxation affecting an unspecified interphalangeal joint of the right middle finger. It indicates that the patient is experiencing ongoing symptoms or limitations directly related to a past subluxation event, rather than an acute injury. The joint involved is not specified as proximal or distal.

Use this code for patients presenting with persistent pain, instability, or reduced range of motion in the right middle finger's interphalangeal joint, where a previous subluxation has been diagnosed and treated, but residual effects remain. This is appropriate for follow-up visits after initial injury management, or when chronic symptoms are the primary complaint.

• Ensure documentation clearly states "sequela" or "chronic" to support the seventh character 'S'.
• Verify the affected finger is specifically the right middle finger and not another digit.
• If the specific interphalangeal joint (PIP vs. DIP) is known, a more specific code should be sought.
