What is the primary use of CPT code 68761?

  1. Closure of the lacrimal punctum by plug

  2. Removal of foreign body from the eye

  3. Comprehensive eye exam

  4. Measurement of visual acuity

The correct answer is: Closure of the lacrimal punctum by plug

CPT code 68761 is specifically designated for the procedure of occlusion of the lacrimal punctum by means of a plug. This procedure is typically performed to treat conditions such as dry eye syndrome, where tear drainage is reduced to improve the overall moisture of the eye. The lacrimal punctum is the small opening on the eyelid margin that allows tears to drain from the eye into the nasal cavity. By using a plug, the drainage is blocked, which helps retain tears on the ocular surface for an extended period, providing relief to patients with insufficient tear production. This understanding clarifies the focus of the procedure associated with the code, which is fundamentally about improving tear retention rather than removing foreign bodies, conducting comprehensive eye examinations, or measuring visual acuity, all of which involve different procedures and corresponding codes.
