Nondisp avuls fx tuberosity of unsp calcaneus, 7thP

This code describes a specific type of foot injury: an avulsion fracture of the calcaneal tuberosity, meaning a small piece of bone has been pulled away by a tendon or ligament, but the main bone fragments remain in their normal anatomical position. The "subsequent encounter" indicates the patient is receiving follow-up care for a fracture that has not healed correctly, specifically with malunion.

This code is appropriate for documenting follow-up visits where a patient's previously diagnosed nondisplaced avulsion fracture of the calcaneal tuberosity is healing improperly, resulting in malunion. This would include evaluations for ongoing pain, functional limitations, or imaging studies confirming the malunion during the healing phase. It should be used when the focus of the encounter is on managing the complications of the fracture's healing.

• Always use in conjunction with an external cause code if the injury mechanism is known.
• Ensure documentation clearly supports malunion, not just delayed healing or nonunion.
• Verify the specific calcaneal location (tuberosity) and fracture type (avulsion, nondisplaced) are documented.
