Nondisp fx of middle phalanx of unspecified finger, 7thK

This code describes a situation where a fracture of the middle bone of an unspecified finger has not healed properly after an initial treatment. The bone fragments remain in their anatomical position, meaning they are not displaced. This diagnosis indicates a complication in the healing process, specifically a nonunion, during a follow-up visit.

This code is appropriate for documenting a patient's visit where a previously diagnosed and treated nondisplaced middle phalanx fracture of an unspecified finger is now confirmed to have failed to unite. It should be used during subsequent encounters when the nonunion is the primary focus of the visit, such as for evaluation of healing progress or planning for further intervention.

• Ensure documentation clearly states "nonunion" and specifies "nondisplaced" for the middle phalanx of an unspecified finger.
• Verify this is a "subsequent encounter" for the fracture, not the initial treatment.
• Confirm the finger is indeed "unspecified" in the medical record; if a specific finger is documented, a more precise code should be used.
