Unspecified superficial injury of anus, sequela

This code indicates a past, healed, or residual condition resulting from an unspecified superficial injury to the anus. It signifies that the original injury, such as a contusion, abrasion, or blister, has resolved, but there are lasting effects or complications directly attributable to it. The specific nature of the original superficial injury is not documented or is unknown.

Use this code when a patient presents with a current condition or symptom that is a direct consequence of a previously sustained, unspecified superficial injury to the anus. This is appropriate for follow-up encounters where the acute phase of the injury has passed, but the sequela is being addressed. It should be assigned when the original injury is no longer present, but its long-term impact is relevant to the current encounter.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela being treated.
• Ensure documentation clearly links the current condition to a past superficial anal injury.
• Do not use for acute injuries; this code is exclusively for sequelae.
