Nondisp comminuted fx shaft of humerus, unsp arm, sequela

This code describes a long-term complication or late effect stemming from a comminuted fracture of the humeral shaft, where the bone fragments remain in their anatomical position. It indicates that the initial injury has healed, but the patient is still experiencing residual issues directly related to that fracture. The specific arm affected is not documented.

Apply this code when a patient presents with a chronic condition, disability, or deformity that is a direct consequence of a previously sustained nondisplaced comminuted humeral shaft fracture. This includes scenarios like persistent pain, limited range of motion, nonunion, malunion, or nerve damage that developed after the initial healing period. It should be used for follow-up encounters after the acute phase of treatment.

• Always sequence this sequela code first, followed by a code describing the specific residual condition (e.g., M25.51_ for pain in shoulder).
• Ensure documentation clearly links the current condition to the previous humeral shaft fracture.
• Verify that the fracture was explicitly documented as "nondisplaced" and "comminuted" and that the encounter is for a late effect.
