Sltr-haris Type III physeal fx unspecified metatarsal, 7thK

This code signifies a Salter-Harris Type III fracture affecting the growth plate and epiphysis of an unstated metatarsal bone in the foot. The "subsequent encounter" indicates that this is not the initial treatment for the fracture, and "nonunion" specifies that the bone fragments have failed to heal together after a typical healing period.

This code is appropriate for follow-up visits where a patient is being managed for a previously diagnosed Salter-Harris Type III metatarsal fracture that has not united. This includes scenarios where further intervention (e.g., surgery, bone stimulation) is being considered or performed due to the nonunion, or during ongoing monitoring of the nonunion.

• Ensure documentation clearly states a Salter-Harris Type III fracture and specifies "nonunion" for the metatarsal.
• Verify that the encounter is indeed subsequent to the initial fracture treatment.
• If the specific metatarsal is known, a more precise code from the S99.13- series should be used.
