Nondisp commnt fx shaft of ulna, l arm, 7thP

This code indicates a left ulna shaft fracture that is broken into multiple fragments (comminuted) but remains in its anatomical position (nondisplaced). The patient is in a later stage of healing, and the fracture has healed incorrectly, resulting in a malunion.

Use this code for follow-up encounters where a patient is being treated for complications arising from a previously sustained, closed, comminuted, nondisplaced fracture of the shaft of the left ulna, specifically when malunion is identified. This would apply to situations like assessing the functional impact of the malunion or planning corrective procedures.

• Ensure documentation clearly specifies "left arm" and "ulna shaft" to differentiate from other forearm bones or locations.
• Confirm the fracture is "nondisplaced" and "comminuted" as these are specific characteristics of this code.
• Verify the encounter is "subsequent" and that "malunion" is the documented complication of the closed fracture.
