Fx unsp carpal bone, unsp wrist, subs for fx w delay heal

This code signifies a fracture of any of the eight carpal bones in the wrist, where the specific bone involved is not documented. It indicates that the patient is in a subsequent phase of treatment for this fracture, and the healing process is progressing slower than expected.

Apply this code when a patient presents for follow-up care of an unspecific carpal bone fracture, and the provider explicitly documents delayed healing. This is appropriate for situations where the initial injury occurred previously, and the current encounter focuses on managing the ongoing, slow recovery.

• Ensure documentation clearly states "delayed healing" for a subsequent encounter.
• Avoid using this code if a specific carpal bone is identified; instead, use a more precise code for that bone.
• This code is for an unspecified wrist; if the laterality (left or right) is known, a more specific code should be chosen.
