Contusion of unspecified part of head, sequela

This code signifies a bruise to an unspecified area of the head, representing a residual effect or complication from an initial injury that has healed. It indicates that the contusion itself is no longer an acute problem, but its long-term consequences are being addressed.

Use this code when a patient presents with a condition or symptom that is a direct result of a previously sustained head contusion, and the specific location of the original bruise on the head was not documented. Documentation should clearly link the current condition to the prior head contusion and specify that it is a sequela.

• Ensure documentation explicitly states "sequela" or describes a chronic condition resulting from a past head contusion.
• Do not use for acute head contusions; those require codes from the S00.93XA-S00.93XD series.
• Always sequence this code after the code for the specific sequela being treated (e.g., chronic headache, cognitive deficits).
