Crushing injury of unspecified knee, sequela

This diagnosis code indicates a crushing injury to an unspecified knee that has resulted in a long-term complication or residual effect. This means the initial acute injury has healed, but the patient continues to experience issues directly attributable to that past trauma.

Apply this code when documenting a patient presenting with a chronic condition or sequela (e.g., chronic pain, stiffness, limited range of motion, arthritis) that is a direct result of a previously sustained crushing injury to an unspecified knee. This code 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 (e.g., M25.56_ for knee pain).
• Ensure documentation clearly links the current condition to a past crushing injury of the knee.
• The "S" at the end signifies "sequela," indicating a late effect of an injury.
