Nondisp avulsion fx tuberosity of unsp calcaneus, sequela

This code describes a healed or residual effect of a fracture where a small piece of bone was pulled away from the main calcaneus (heel bone) by a tendon or ligament, but the bone fragments remained in their normal anatomical position. The injury occurred in an unspecified heel bone, and the patient is now presenting for care related to the long-term consequences of this past injury.

Apply this code when documenting a patient encounter for a chronic condition or complication directly resulting from a previously sustained nondisplaced avulsion fracture of the calcaneal tuberosity. This includes ongoing pain, stiffness, or functional limitations attributed to the old injury. It should not be used for the initial treatment of the acute fracture.

• Assign this code as a secondary diagnosis when the sequela is not the primary reason for the encounter but is being addressed.
• Ensure documentation clearly links the current symptoms or condition to the past avulsion fracture.
• Do not use this code for acute or subacute fracture care; reserve it strictly for sequelae.
