Nondisp fx of base of unspecified metacarpal bone, sequela

This code signifies a long-term complication or late effect stemming from a fracture at the base of any metacarpal bone in the hand, where the bone fragments remained in their normal anatomical alignment during the initial injury. It indicates that the original injury has resolved, but residual issues related to that fracture are now present.

Apply this code when documenting a patient presenting with a current condition directly attributable to a previously sustained, nondisplaced fracture of the base of an unspecified metacarpal. This is appropriate for conditions such as chronic pain, stiffness, deformity, or functional limitations that are a direct sequela of the old fracture.

• Always use a second code to identify the specific sequela (e.g., M79.64- for pain in hand and fingers).
• Ensure documentation clearly links the current condition to the old, nondisplaced metacarpal base fracture.
• This code is for an unspecified metacarpal; if the specific metacarpal is known, a more precise code should be used.
