Disp fx of prox phalanx of thmb, subs for fx w delay heal

This code signifies a fracture of the proximal phalanx of the thumb, where the bone fragments are no longer in their normal alignment. The "unspecified thumb" indicates that the laterality (left or right) is not documented. The "subsequent encounter with delayed healing" specifies that this is not the initial treatment for the fracture, and the healing process is taking longer than expected.

Use this code for follow-up visits where a patient is being treated for a thumb proximal phalanx fracture that is not healing at the anticipated rate. This applies when the fracture was initially displaced and the specific thumb (left or right) is not documented in the medical record. This code would be appropriate for scenarios like cast changes, repeat imaging, or discussions about further interventions due to slow healing.

• Ensure documentation clearly states "delayed healing" and that the encounter is not the initial treatment.
• Verify that the fracture is of the proximal phalanx and not another part of the thumb.
• If laterality (left or right thumb) is documented, a more specific code should be used.
