Sprain of medial collateral ligament of right knee, sequela

This code signifies a long-term complication or residual effect stemming from a prior injury to the medial collateral ligament (MCL) of the right knee. This could include chronic instability, persistent pain, stiffness, or degenerative changes that are a direct result of the original sprain, rather than an acute injury.

Apply this code when documenting conditions that are a direct consequence of a previously sustained right MCL sprain, and the acute phase of the injury has passed. This is appropriate for follow-up encounters addressing ongoing issues related to the old injury, such as chronic pain management or rehabilitation for residual instability.

• Always use this code with an additional code to specify the nature of the sequela (e.g., chronic pain, instability).
• Ensure documentation clearly links the current condition to the previous right MCL sprain.
• Do not use for acute or subacute MCL sprains; those require codes from the initial or subsequent encounter categories.
