Dislocation of unsp interphalangeal joint of finger, subs

This code signifies a dislocation of an interphalangeal joint in any finger other than the thumb, where the specific joint (proximal or distal) is not documented. This particular code is for a patient receiving routine follow-up care during the healing or recovery phase after initial treatment for the dislocation.

Apply this code when a patient presents for follow-up appointments, cast changes, or physical therapy after a previously treated interphalangeal joint dislocation of a finger other than the thumb, and the specific joint involved was not specified in the initial diagnosis. It is appropriate for encounters occurring after the initial active treatment phase.

• Ensure the "D" seventh character is appropriate for subsequent care, not initial or sequela.
• Confirm documentation specifies "unspecified interphalangeal joint" and "other finger" (not thumb).
• If the specific interphalangeal joint (PIP or DIP) is known, a more specific code should be used.
