Subluxation of unsp interphaln joint of unsp finger, sequela

This code signifies a partial dislocation of an interphalangeal joint in any finger, where the specific joint and finger are not documented. It is used to indicate a residual condition or late effect of a previous injury, rather than an acute event. The joint surfaces are no longer perfectly aligned, but still maintain some contact.

Apply this code when documentation clearly indicates a sequela of a subluxation affecting an interphalangeal joint, and the specific finger or joint (e.g., DIP, PIP) is not specified. This is appropriate for chronic pain, stiffness, or deformity resulting from a past subluxation. Do not use for acute or current subluxations.

• Requires a seventh character "S" to indicate sequela.
• Only use when the specific interphalangeal joint and finger are truly unspecified in the medical record.
• Always attempt to query for more specific anatomical detail if available to use a more precise code.
