What 92020 covers

Gonioscopy lets the examiner see the drainage angle where the iris meets the cornea, which cannot be viewed directly during a routine slit-lamp examination. An ophthalmologist or optometrist typically places a goniolens on the eye after topical anesthesia and assesses angle width and features such as trabecular pigmentation, peripheral anterior synechiae, neovascularization, or angle recession. Common indications include glaucoma evaluation, narrow angles, pigment dispersion, and blunt ocular trauma. The examination is often performed in an office or outpatient eye clinic.

Report gonioscopy in addition to an eye exam or E/M visit when a diagnostic angle examination is medically necessary and performed. Documentation should identify the indication, eye or eyes examined, angle findings, and clinical interpretation; an angle grade and findings by quadrant can add useful detail. CMS prices 92020 as bilateral, so report one unit for examination of one or both eyes; modifier 50 does not increase payment. Viewing the angle solely to guide laser trabeculoplasty is part of that procedure, not a separate diagnostic gonioscopy.
