Nondisp fx of lateral malleolus of right fibula, sequela

This code indicates a healed or chronic condition resulting from a prior nondisplaced fracture of the lateral malleolus in the right fibula. It signifies that the initial injury has resolved, but the patient is now experiencing residual effects or complications directly attributable to that past fracture.

Apply this code when documenting a patient presenting with long-term issues such as pain, stiffness, limited range of motion, or post-traumatic arthritis in the right ankle, where these symptoms are a direct consequence of a previously sustained nondisplaced right lateral malleolus fracture. This code is appropriate for follow-up encounters occurring after the initial healing period of the fracture.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., M25.571 for pain in right ankle).
• Ensure documentation clearly links the current condition to the past nondisplaced right lateral malleolus fracture.
• Verify that the fracture was indeed nondisplaced and located in the lateral malleolus of the right fibula.
