Periprosth osteolysis of internal prosthetic joint, sequela

This code signifies the long-term effects of bone breakdown around an internal prosthetic joint, excluding those of the hip or knee. Periprosthetic osteolysis is a destructive process where bone is resorbed due to an inflammatory reaction, often triggered by wear particles from the implant. This can lead to implant loosening, pain, and potential need for revision surgery.

Use this code when documenting the sequela of periprosthetic osteolysis affecting an internal prosthetic joint other than the hip or knee, such as a shoulder, ankle, or elbow replacement. This code is appropriate for chronic conditions or complications arising from the initial osteolysis, even if the acute phase has passed. It should be applied when the patient is presenting for evaluation or management of these long-term effects.

• Always sequence this code after the primary diagnosis describing the current condition or reason for the encounter.
• Ensure the documentation clearly specifies "other internal prosthetic joint" to differentiate from hip or knee involvement.
• This "S" seventh character indicates sequela, meaning the patient is experiencing residual effects or complications of a previous acute condition.
