Unsp fracture of right ischium, subs for fx w nonunion

This code signifies an unconfirmed fracture of the right ischium that has failed to heal properly after initial treatment. "Nonunion" indicates that the bone fragments have not united and are not expected to do so without further intervention. This is a follow-up encounter for this specific, ongoing issue.

Use this code for patients presenting for follow-up care of a right ischial fracture where the initial treatment has not resulted in bone healing, and the specific type of fracture (e.g., displaced, nondisplaced) was not documented or is unknown. This applies to subsequent visits for management of the nonunion, such as evaluation for surgical intervention or continued conservative management.

• Ensure documentation clearly states "nonunion" and specifies the right ischium.
• Verify this is a subsequent encounter, not the initial treatment for the fracture.
• If the specific type of ischial fracture is known and documented, a more specific code should be used instead.
