Mech compl of unspecified cardiac device, sequela

This code signifies a long-term or residual effect resulting from a past mechanical issue with an unspecified cardiac device. It indicates that the initial complication has resolved, but the patient continues to experience a consequence directly attributable to that prior event.

Apply this code when documentation clearly links a current patient condition to a previously experienced mechanical complication of a cardiac device, and the acute phase of that complication has passed. This is appropriate for follow-up encounters addressing the lasting impact, rather than the initial acute event.

• Ensure the documentation explicitly states the condition is a "sequela" or "due to a previous complication" of a cardiac device.
• This code requires a seventh character 'S' for sequela, indicating the long-term nature of the complication.
• Always code the specific nature of the sequela first, if known, followed by this code to provide complete clinical context.
