Sprain of lateral collateral ligament of left knee, subs

This code signifies a sprain affecting the outer collateral ligament of the left knee, indicating damage to the fibrous tissue connecting the femur and fibula on the lateral side. The "D" suffix specifies that this is a subsequent encounter, meaning the patient is receiving routine care during the healing or recovery phase of the injury.

Apply this code when a patient presents for follow-up care, such as physical therapy, re-evaluation, or medication management, for a previously diagnosed sprain of the left knee's lateral collateral ligament. This includes situations where the initial injury has already been treated and the patient is now in the healing process.

• Ensure documentation clearly indicates the left knee and the specific lateral collateral ligament involvement.
• The "D" seventh character is crucial for subsequent encounters; avoid using "A" (initial) or "S" (sequela) for this scenario.
• Verify that the encounter type aligns with follow-up care for an existing injury, not a new injury or a complication.
