Path fx, unsp ulna and radius, subs for fx w routn heal

This code signifies a pathological fracture of an unspecified ulna and/or radius that is currently in the healing phase, with the healing process progressing routinely. A pathological fracture occurs due to a disease process weakening the bone, rather than from trauma. This specific code indicates a follow-up encounter for monitoring healing.

This code is appropriate for subsequent encounters when a patient is receiving ongoing care for a pathological fracture of the forearm (ulna and/or radius) that is healing as expected. Documentation should clearly state "pathological fracture" and indicate routine healing, often seen in follow-up notes after initial treatment. It applies when the fracture is not new, not malunion/nonunion, and not complicated.

• Requires documentation of "pathological fracture" and "routine healing" or similar terms indicating normal progression.
• Distinguish from initial encounter codes (A) or codes for delayed healing/nonunion/malunion (G, K, P, S).
• Ensure the laterality (left/right) is not specified in the documentation; if specified, a more precise code should be used.
