Sublingual varices

This code describes the presence of abnormally dilated and tortuous veins located on the ventral surface of the tongue. These varices are typically benign and often asymptomatic, appearing as dark blue or purple lesions. They result from venous insufficiency or increased venous pressure within the sublingual vasculature.

Use this code when documentation explicitly states "sublingual varices" or "lingual varices" identified during an oral examination. This condition is frequently observed in older adults and may be noted incidentally during routine dental or medical check-ups. Supporting documentation would include notes from a dentist, oral surgeon, or physician describing the presence and location of these varicosities.

• Do not confuse with other oral lesions or vascular malformations; ensure the documentation specifically identifies them as varices.
• This code is for the presence of the varices themselves, not for any associated symptoms or complications, which would be coded separately if present.
• Typically an incidental finding, this code would often be a secondary diagnosis unless the varices are the primary reason for the encounter (e.g., for evaluation of a new oral lesion).
