Fracture of unspecified part of neck of right femur, sequela

This code signifies a long-term complication or late effect resulting from a fracture that previously occurred in an unspecified part of the neck of the right femur. It indicates that the initial injury has healed, but the patient is still experiencing residual issues directly attributable to that past fracture.

Apply this code when documenting conditions such as chronic pain, nonunion, malunion, avascular necrosis, or degenerative changes that are a direct consequence of a healed or resolving fracture of the right femoral neck. This is appropriate for encounters addressing these persistent problems, not the initial acute injury.

• Always sequence this code after the code for the specific sequela being treated (e.g., M84.451A for nonunion of right femur).
• Ensure documentation clearly links the current condition to the previous right femoral neck fracture.
• Do not use this code for acute or subacute fractures; those require codes from the initial encounter or subsequent encounter categories.
