Periprosth fx around internal prosth r knee jt, sequela

This code signifies a fracture that occurs in the bone surrounding a previously implanted prosthetic right knee joint, representing a late effect or complication. It indicates that the fracture is a consequence of the presence of the prosthetic joint, rather than an acute injury.

Apply this code when documentation specifies a periprosthetic fracture of the right knee that is a sequela, meaning it's a long-term consequence or complication. This typically applies to fractures identified after the initial healing period of the prosthetic implantation, often due to stress, loosening, or other factors related to the prosthesis.

• Ensure documentation clearly states "sequela" or indicates a chronic or late-onset fracture related to the prosthesis.
• Distinguish from acute periprosthetic fractures, which would use codes without the "S" seventh character.
• Always code the underlying cause of the fracture (e.g., osteoporosis, fall) if known and documented, in addition to this code.
