Oth nondisp fx of base of first MC bone, unsp hand, sequela

This code signifies a healed or residual condition resulting from a previous nondisplaced fracture at the base of the first metacarpal bone (thumb) in an unspecified hand. It indicates that the initial injury has resolved, but there are lingering effects or complications.

Apply this code when documenting a patient presenting with ongoing symptoms (e.g., pain, stiffness, limited range of motion) directly attributable to a previously sustained, nondisplaced fracture of the first metacarpal base. This is appropriate for follow-up encounters after the acute phase of healing has passed.

• Always use an additional code to specify the nature of the sequela (e.g., M25.54- for pain in hand).
• Ensure documentation clearly links the current condition to the old fracture.
• Do not use for acute or subacute fractures; those require codes from the initial encounter or subsequent encounter categories.
