Unspecified complication of procedure, subsequent encounter

This code signifies a complication arising from a medical or surgical procedure that is not specifically identified, and the patient is receiving follow-up care for this complication. It indicates that the nature of the adverse event is unknown or not documented with sufficient detail to assign a more specific code.

Use this code when a patient presents for a subsequent encounter related to an uncharacterized post-procedural issue, such as persistent pain, swelling, or general malaise, where the exact cause or type of complication has not yet been determined or definitively diagnosed. It is appropriate when the documentation only states "complication of procedure" without further specificity.

• Always strive for a more specific complication code if documentation permits.
• This code should be used as a last resort when no other specific complication code can be assigned.
• The "D" seventh character indicates a subsequent encounter for follow-up care of the complication.
