Unsp fx lower end unsp ulna, subs for clos fx w delay heal

This code indicates a fracture of the lower portion of the ulna, where the specific type of fracture is not documented. The patient is in a subsequent phase of care, meaning the initial treatment has been rendered, and the fracture is now showing delayed healing, but the skin remains intact over the fracture site.

Apply this code for follow-up encounters of an ulnar fracture that is not healing as expected, but is still considered a closed injury. This is appropriate when the medical record does not specify the exact nature of the fracture (e.g., transverse, oblique, comminuted) or the specific location on the lower end of the ulna.

• Requires a seventh character for the encounter type; 'G' indicates subsequent encounter for closed fracture with delayed healing.
• Only use when the fracture type and specific location on the lower ulna are truly unspecified in the documentation.
• Ensure documentation clearly supports delayed healing for a closed fracture.
