Stress fracture, right foot, subs for fx w delay heal

This code signifies a stress fracture in the right foot that is currently undergoing treatment for delayed healing. It indicates that the patient has previously received initial care for this specific fracture and the healing process is not progressing as expected.

Apply this code when documentation explicitly states a stress fracture of the right foot with delayed healing, and the patient is presenting for follow-up care related to this ongoing issue. This code is appropriate for encounters where the provider is monitoring the slow healing, adjusting treatment, or performing interventions for the delayed union.

• Ensure documentation clearly specifies "delayed healing" and the specific anatomical site (right foot).
• Do not use for initial encounters or for fractures that are healing normally.
• Always sequence this code after any associated external cause codes, if applicable.
