About 92100: Serial intraocular pressure measurement
Serial tonometry records repeated eye-pressure readings over an extended period to assess pressure variation in patients with suspected or known glaucoma.
Serial tonometry captures intraocular pressure at multiple points over an extended period, rather than relying on a single reading. An ophthalmologist or optometrist may use it when evaluating suspected or established glaucoma, particularly when pressure fluctuation is clinically relevant. Readings are obtained in an eye-care setting, with the clinician interpreting the results and documenting a report.
Report 92100 when the service includes the repeated measurements and interpretation, not for a single pressure check. Documentation should identify the clinical reason for serial testing, the readings and times, the eye or eyes measured, and the interpretation. CMS prices this code as bilateral; adding modifier 50 does not increase payment.

92100 billing questions
When should 92100 be chosen instead of a single tonometry measurement?
Use 92100 when multiple intraocular pressure readings are obtained over an extended period and interpreted. A single pressure reading does not describe serial tonometry.
Can modifier 50 be used to increase payment for bilateral testing?
No. CMS prices 92100 as bilateral, and modifier 50 does not increase payment.
What documentation supports 92100?
Record the clinical reason for serial testing, the pressure readings and measurement times, the eye or eyes tested, and the clinician’s interpretation.
Is 92100 appropriate for every pressure check during a glaucoma visit?
No. The service must involve repeated pressure measurements over an extended period with interpretation, rather than only a routine single reading.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
