Lacerat great saphenous at lower leg level, right leg, subs

This code indicates a laceration of the greater saphenous vein in the right lower leg that is currently receiving active treatment or follow-up care after the initial encounter. This injury involves a cut or tear to the major superficial vein running along the inner aspect of the right lower leg.

Use this code for subsequent encounters when a patient is being seen for ongoing management, such as wound care, infection control, or monitoring of healing, for a previously diagnosed laceration of the right greater saphenous vein. This applies after the initial treatment has been rendered and the patient is no longer in the acute phase of care.

• Ensure documentation specifies the right lower leg and the greater saphenous vein.
• Confirm the encounter is for follow-up care, not the initial treatment, to justify the "D" seventh character.
• Pair with external cause codes (V, W, X, Y) to describe the circumstances of the injury, if known and applicable.
