Subluxation of unsp interphalangeal joint of finger, sequela

This code signifies a persistent partial dislocation (subluxation) affecting an unspecified interphalangeal joint of any finger other than the thumb or index finger. The "sequela" designation indicates that this subluxation is a late effect or complication of an earlier injury or condition, rather than an acute event.

Use this code for documentation of chronic or long-standing interphalangeal joint subluxation in fingers other than the thumb or index finger. This applies when the initial injury has resolved, but the joint instability and partial dislocation remain as a lasting consequence. It is appropriate when the specific interphalangeal joint (e.g., PIP vs. DIP) is not specified in the clinical documentation.

• Ensure documentation clearly supports a "sequela" status, indicating a residual condition from a prior injury.
• Verify that the affected finger is not the thumb or index finger, and that the specific interphalangeal joint is unspecified.
• Always code the underlying cause of the sequela if known and still relevant for patient management.
