Crushing injury of right knee, sequela

This code signifies a long-term complication or residual effect stemming from a crushing injury to the right knee. These sequelae can include chronic pain, limited range of motion, instability, nerve damage, or persistent soft tissue damage that developed after the initial injury has healed. It indicates that the patient is currently experiencing issues directly attributable to that past trauma.

This code is appropriate for documenting ongoing conditions or disabilities in the right knee that are a direct consequence of a previously sustained crushing injury. It should be used when the acute phase of the original injury has passed, and the patient is being treated for the chronic effects. Examples include follow-up visits for post-traumatic arthritis, chronic ligamentous laxity, or persistent neurological deficits resulting from the crushing force.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated (e.g., M17.11 for post-traumatic osteoarthritis of the right knee).
• Ensure documentation clearly links the current knee condition to a past crushing injury.
• The "S" in the 7th character indicates sequela; verify that the medical record supports this designation.
