Path fracture, right finger(s), subs for fx w nonunion

This code signifies a pathological fracture affecting one or more fingers of the right hand, where the fracture has failed to heal properly (nonunion) and the patient is receiving ongoing treatment for this specific complication. A pathological fracture occurs due to a disease process weakening the bone, rather than from trauma.

Apply this code for patients presenting for follow-up care, such as cast changes, physical therapy, or surgical intervention, for a right finger pathological fracture that has been diagnosed with nonunion. Documentation should clearly indicate the pathological nature of the fracture, its location in the right finger(s), and the ongoing management of the nonunion.

• Always sequence this code after the underlying disease causing the pathological fracture (e.g., osteoporosis, neoplasm).
• Ensure documentation explicitly states "nonunion" and specifies the right finger(s) to support this code.
• Distinguish from initial encounters (A), subsequent encounters for routine healing (D), or sequela (S) codes for healed fractures with residual effects.
