Mech compl of biological heart valve graft, sequela

This code signifies a long-term or residual mechanical issue with a biological heart valve graft that is not specifically classified elsewhere. It indicates that the initial complication has resolved, but the patient continues to experience a lasting effect or condition directly attributable to that past mechanical problem.

Use this code when documenting a patient presenting with a chronic or residual symptom, sign, or condition that is a direct consequence of a previously treated or resolved mechanical complication of a biological heart valve graft. This applies to situations where the acute phase of the complication has passed, but its impact persists.

• Requires a seventh character "S" to indicate sequela, meaning the late effect of a previous complication.
• Always sequence this code after the code(s) for the specific sequela being treated or evaluated.
• Do not use for acute or current mechanical complications; those would utilize the appropriate acute complication code without the "S" seventh character.
