Ophthalmic Coding Specialist Practice Test

CPT code 66761 is primarily used for which condition?

1. Closed angle glaucoma

2. Open angle glaucoma

3. Corneal edema

4. Retinal detachment

The correct answer is: Closed angle glaucoma

CPT code 66761 specifically refers to a procedure known as "Transluminal laser therapy of aqueous outflow tract, including anterior chamber, for glaucoma." This code is mainly utilized in the treatment of closed angle glaucoma, where there is a blockage of the aqueous humor outflow due to a narrowing or closure of the anterior chamber angle. The purpose of this procedure is to enhance the drainage of intraocular fluid and lower intraocular pressure, which is crucial in managing closed angle glaucoma. Closed angle glaucoma can lead to significant vision loss and requires urgent treatment. The procedure associated with this CPT code addresses the structural issues causing the glaucoma, making it a vital option for patients suffering from this specific condition. In contrast, other options like open angle glaucoma relate to different treatment methods and codes more focused on surgeries or medications tailored primarily for that condition.
