Medial subluxation of proximal end of tibia, unsp knee, init

This code signifies a partial dislocation of the upper part of the shin bone (tibia) where it shifts inward (medially) relative to the thigh bone (femur). This injury affects an unspecified knee joint, meaning the laterality (left or right) is not documented. It represents the initial treatment for this condition.

Use this code when documentation indicates a medial subluxation of the proximal tibia without specifying which knee is affected, and the patient is receiving active treatment for the injury. This is appropriate for the first encounter where the injury is diagnosed and managed.

• Ensure the documentation explicitly states "medial subluxation of proximal tibia" and does not specify laterality.
• Verify that this is the patient's initial encounter for this specific injury, not a follow-up or sequela.
• If laterality (left or right knee) is documented, a more specific code should be used.
