Crushing injury of left knee, sequela

This code signifies the long-term effects or complications arising from a crushing injury to the left knee. These sequelae can include chronic pain, limited range of motion, instability, nerve damage, or degenerative changes that manifest after the initial acute injury has healed. It indicates that the patient is presenting for treatment of these residual conditions.

Use this code when documenting encounters for the management of chronic issues directly attributable to a past crushing injury of the left knee. This includes follow-up visits for ongoing physical therapy, pain management, or surgical interventions addressing the lasting damage. It is appropriate when the acute phase of the original injury has passed.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated (e.g., chronic pain, osteoarthritis).
• Ensure documentation clearly links the current condition to the previous crushing injury of the left knee.
• The "S" in the 7th character indicates sequela, meaning the patient is being seen for the late effects of the injury.
