ICD-10-CMSalter-Harris Type III physeal fracture of unspecified metatarsal, subsequent encounter for fracture with delayed healing
This code describes a specific type of growth plate fracture (Salter-Harris Type III) affecting an unknown metatarsal bone in the foot. The fracture is currently in a phase of delayed healing, meaning the bone is not mending at the expected rate.
This code is appropriate for follow-up encounters where a patient with a previously diagnosed Salter-Harris Type III fracture of an unspecified metatarsal is being monitored for healing, and the physician documents that the healing process is slower than anticipated. It would be used after the initial treatment phase.
