Disp fx of base of 4th MC bone, r hand, 7thG

This code signifies a break at the base of the fourth metacarpal bone in the right hand, where the bone fragments are not properly aligned. The patient is in a phase of treatment where the fracture is not healing at the expected rate.

Apply this code when documenting follow-up care for a right fourth metacarpal base fracture that was initially displaced and is now exhibiting delayed union. This includes situations where the patient is receiving ongoing management, such as cast changes, physical therapy, or surgical intervention, due to the slow healing process.

• Ensure documentation clearly states "delayed healing" for the fracture.
• Verify the fracture is specifically of the "base" of the fourth metacarpal and on the "right" hand.
• Confirm this is a "subsequent encounter" for the fracture, not the initial treatment.
