Leakage of heart valve prosthesis, initial encounter

This code signifies the initial diagnosis and treatment of a heart valve prosthesis that is malfunctioning due to leakage. This leakage, also known as regurgitation, means the artificial valve is not closing properly, allowing blood to flow backward through the heart. It indicates the first time this specific complication is being addressed.

Apply this code when a patient presents with symptoms or findings consistent with a leaking prosthetic heart valve, and this is the initial encounter for the management of this particular complication. This includes initial diagnostic work-up, surgical repair, or medical management for a newly identified leak.

• Ensure documentation clearly specifies "leakage" or "regurgitation" of the prosthetic valve, not just general malfunction.
• Confirm this is the initial encounter for the treatment of this specific leakage. Subsequent encounters for the same issue would use a different seventh character.
• Always code the specific type of prosthetic valve (e.g., mechanical, tissue) if documented, using additional codes as appropriate.
