Abrasion, right knee, sequela

This code signifies a superficial injury to the right knee, specifically an abrasion, where the acute phase of the injury has passed, and the current encounter addresses a long-term effect or complication resulting from that initial abrasion. This could include persistent scarring, chronic pain, or functional limitations directly attributable to the original wound.

Use this code when documenting a patient visit for a condition that is a direct consequence of a previously sustained abrasion to the right knee. This applies to follow-up care for complications that arise after the initial healing period, such as keloid formation, chronic dermatitis at the site, or nerve damage from the original injury.

• Ensure documentation clearly links the current condition to the prior right knee abrasion.
• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated.
• Verify that the "S" seventh character is appropriate, indicating a sequela, rather than an initial or subsequent encounter for an acute injury.
