Stress fracture, unsp site, subs for fx w routn heal

This code signifies a stress fracture, which is a small crack in a bone resulting from repetitive stress rather than a single acute injury, located at an unspecified anatomical site. The "subsequent encounter" indicates the patient is receiving routine follow-up care during the healing phase of the fracture.

Use this code when a patient presents for routine follow-up care of a previously diagnosed stress fracture where the specific bone involved is not documented. This applies when the fracture is healing as expected without complications. Documentation should clearly state "stress fracture," "unspecified site," and indicate a follow-up visit for routine healing.

• Ensure documentation specifies "stress fracture" and not an acute traumatic fracture.
• Only use "unspecified site" when the specific bone involved is genuinely unknown or not documented. Prioritize more specific codes if available.
• The "XD" seventh character indicates routine healing; choose other seventh characters (e.g., XG, XS) for delayed healing, nonunion, or sequelae.
