Nondisp fx of base of 4th MC bone, l hand, 7thG

This code signifies a left-sided fracture at the base of the fourth metacarpal bone that is not dislocated. It indicates that the patient is in a subsequent phase of treatment, and the fracture is experiencing delayed healing.

This code is appropriate for follow-up encounters where a patient with a previously diagnosed nondisplaced fracture of the base of the left fourth metacarpal is being monitored for healing progress, and the clinician notes that the healing process is taking longer than expected. This would typically involve patients presenting for repeat imaging or clinical assessment after initial treatment.

• Ensure documentation clearly specifies "left hand" and "fourth metacarpal" to support laterality and bone specificity.
• Confirm the "subsequent encounter" status and explicit documentation of "delayed healing" to justify the 7th character 'G'.
• Distinguish from nonunion (7th character 'K') or malunion (7th character 'P'); delayed healing implies eventual union is still expected.
