Subluxation of unsp interphaln joint of l rng fngr, sequela

This code signifies a partial dislocation of an interphalangeal joint within the left ring finger, where the joint surfaces are no longer perfectly aligned but remain in contact. This specific code is used when the exact interphalangeal joint (proximal or distal) is not documented. It indicates that the subluxation is a long-term complication or residual effect of an initial injury.

Use this code when documentation clearly states a subluxation of an unspecified interphalangeal joint of the left ring finger, and the condition is being treated as a sequela. This applies to follow-up encounters for chronic instability, pain, or functional limitation resulting from a past subluxation. It is appropriate when the acute injury has resolved, but the subluxation persists as a lasting issue.

• Ensure the documentation explicitly states "sequela" or indicates a chronic condition resulting from a previous injury.
• Verify laterality (left) and the specific digit (ring finger) are clearly documented.
• If the specific interphalangeal joint (proximal or distal) is known, a more specific code should be used.
