Unspecified superficial injury of right knee, sequela

This code indicates a long-term complication or late effect stemming from a superficial injury to the right knee, where the specific type of superficial injury (e.g., abrasion, contusion) is not documented. It signifies that the initial injury has resolved, but residual issues or conditions persist as a direct result.

Use this code when documenting a patient presenting with a current condition directly attributable to a past, unspecified superficial injury of the right knee. This applies when the acute phase of the original injury has passed, and the patient is now experiencing a sequela, such as chronic pain, scarring, or limited range of motion related to that prior injury.

• Requires a seventh character "S" to indicate sequela, meaning the initial injury has healed but its effects are ongoing.
• Do not use for acute injuries; instead, select an appropriate acute injury code.
• Always code the specific nature of the sequela (e.g., chronic pain, scar) first, followed by this sequela code.
