Stress fx, unsp ulna and radius, subs for fx w delay heal

This code signifies a stress fracture affecting either the ulna or radius, where the specific bone is not documented. The patient is in the healing phase following the initial injury, but the fracture is not progressing to union at the expected rate, indicating delayed healing.

Apply this code when documentation indicates a stress fracture of an unspecified forearm bone (ulna or radius) that is not healing normally after the initial treatment. This is used for follow-up encounters where the focus is on managing the delayed healing of the fracture. Supporting documentation would include imaging reports showing incomplete healing and physician notes detailing the delayed union.

• Ensure the documentation explicitly states "stress fracture" and "delayed healing" for an unspecified ulna or radius.
• Do not use this code for initial encounters or for fractures that are healing normally.
• Verify laterality if specified; if not, "unspecified" is appropriate.
