Gonioscopy is an eye examination where an ophthalmologist uses a special lens to view the drainage angle inside the eye, typically performed on patients with glaucoma or suspected glaucoma. This procedure helps determine if the eye's drainage system is open or blocked. Code 92020 is frequently billed alongside other ophthalmology services during the same visit, requiring careful attention to bundling rules.
