Nondisp fx of neck of first MC bone, unsp hand, sequela

This code signifies a healed or residual condition resulting from a fracture of the neck of the first metacarpal bone (thumb metacarpal) that was not displaced at the time of injury. It indicates that the initial fracture has resolved, but there are ongoing effects or complications attributable to the past injury, regardless of which hand was affected.

This code is appropriate when documenting a patient presenting with long-term sequelae such as chronic pain, stiffness, deformity, or functional limitations directly related to a previously sustained, nondisplaced fracture of the first metacarpal neck. It should be used after the initial healing phase of the acute fracture has passed.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela (e.g., M25.54- for pain in hand).
• Ensure documentation clearly links the current condition to the past nondisplaced first metacarpal neck fracture.
• Do not use this code for the initial acute fracture; it is exclusively for sequelae.
