Fx unsp metatarsal bone(s), l foot, subs for fx w delay heal

This code indicates a fracture of one or more metatarsal bones in the left foot where the specific bone(s) involved are not documented. The patient is in a subsequent phase of care, and the fracture is experiencing delayed healing, meaning it is taking longer than expected to unite.

Use this code when a patient presents for follow-up care of a left foot metatarsal fracture that is not healing at the anticipated rate, and the medical record does not specify which metatarsal bone(s) are affected. This applies to ongoing management, such as cast changes, physical therapy, or imaging to assess healing progress.

• Ensure documentation clearly states "delayed healing" for the subsequent encounter.
• Only use this code if the specific metatarsal bone(s) are truly unspecified in the medical record.
• Verify the encounter type is for follow-up care, not initial treatment.
