Infect/inflm reaction due to internal r knee prosth, init

This code signifies an infection or inflammatory response occurring in the right knee, directly attributable to the presence of an internal prosthetic joint. It indicates that the patient is presenting for the initial treatment or management of this specific complication.

Apply this code when a patient presents with signs and symptoms of infection (e.g., fever, purulent drainage, redness, swelling) or inflammation (e.g., persistent pain, swelling, warmth) localized to the right knee, and diagnostic workup confirms the prosthetic joint as the source. This is appropriate for the first encounter related to diagnosing and initiating treatment for this complication.

• Ensure documentation clearly links the infection/inflammation to the right knee prosthesis.
• Confirm this is the initial encounter for this specific complication; subsequent encounters would use a different seventh character.
• Code any associated systemic infection or specific infectious agent separately, if applicable.
