Sprain of lateral collateral ligament of unsp knee, sequela

This code signifies a chronic or late-effect condition resulting from a previous injury to the lateral collateral ligament (LCL) of an unspecified knee. It indicates that the patient is experiencing ongoing symptoms or complications directly attributable to an old LCL sprain, rather than an acute injury.

Apply this code when documentation clearly links current knee problems, such as chronic pain, instability, or limited range of motion, to a past LCL sprain. This is appropriate for patients presenting with residual issues long after the initial acute injury has healed.

• Always ensure the medical record explicitly states "sequela" or "late effect" of a prior LCL sprain.
• Do not use this code for acute or subacute LCL sprains; those require codes from the initial or subsequent encounter categories.
• Verify that the laterality (left or right knee) is truly unspecified in the documentation before using this code.
