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.

92020 billing questions
Should gonioscopy be billed twice or with modifier 50 when both eyes are examined?
No. CMS already prices 92020 as bilateral. Report one unit for examination of one or both eyes; modifier 50 does not increase payment.
Is gonioscopy included in a comprehensive or intermediate eye exam?
The routine examination reported with 92004, 92014, 92002, or 92012 is different from a diagnostic angle examination with a goniolens. Report 92020 separately when the gonioscopy is medically necessary, performed, and documented.
Can gonioscopy be billed on the same day as laser trabeculoplasty or iridotomy?
Using a goniolens solely to guide the laser treatment is part of that procedure, not a separately billable gonioscopy. A distinct diagnostic angle examination requires its own medical necessity and findings.
What documentation supports gonioscopy?
Record the indication, eye or eyes examined, angle findings, and clinical interpretation. An angle grade and details such as synechiae, pigment, or neovascularization help describe the findings.
Which conditions commonly prompt diagnostic gonioscopy?
Examples include suspected or established glaucoma, narrow or potentially occludable angles, pigment dispersion, neovascular glaucoma, and suspected angle recession after trauma. The documented reason for examining the angle should support the service.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
