Nondisp fx of proximal phalanx of left thumb, sequela

This code indicates a long-term complication or late effect stemming from a previously sustained, non-displaced fracture of the bone in the thumb closest to the hand, specifically on the left side. The original fracture has healed, but residual issues related to it are now being addressed.

This code is appropriate when a patient presents with ongoing symptoms or conditions directly attributable to a past, non-displaced fracture of the left thumb's proximal phalanx. Examples include chronic pain, stiffness, limited range of motion, or deformity that developed as a consequence of the original injury after the acute phase has passed.

• Always sequence this "S" (sequela) code after the code(s) describing the specific sequela being treated (e.g., M25.542 for chronic pain in the left hand).
• Ensure documentation clearly links the current condition to the previous left thumb proximal phalanx fracture.
• Do not use this code for acute or subacute fractures; those require codes from the initial or subsequent encounter categories.
