Billing code 95933: Blink reflexMedicare rate & RVUs in Delaware
Reports electrical stimulation and bilateral eye-muscle recordings used to evaluate trigeminal and facial nerve pathways and related brainstem reflex activity.
Medicare pays $84.69 for 95933 in the office in Delaware (Delaware). Which amount applies depends on the service address.
Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 95933 covers
The study electrically stimulates the supraorbital branch of the trigeminal nerve and records reflex activity from the orbicularis oculi muscles on both sides. The responses help assess the sensory trigeminal pathway, brainstem connections, and facial nerve output. Neurologists and other clinicians trained in electrodiagnostic testing commonly use it when evaluating facial weakness, facial sensory symptoms, or suspected brainstem involvement. Testing is generally performed in an outpatient electrodiagnostic laboratory or a hospital setting.
Report 95933 for the blink-reflex study itself, rather than selecting a nerve-conduction code based on the number of nerve-conduction studies. The record should support that stimulation and bilateral recordings were performed and include the clinician’s interpretation of the responses. CMS recognizes professional and technical components: append modifier 26 for the interpretation, modifier TC for the equipment and staff, or report the global service without either modifier when one entity provides both components.
This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

How to choose
- 95910Nerve conduction study
- 95910 represents nerve-conduction testing selected by the number of studies performed. Use 95933 for the blink-reflex evaluation, not as a substitute for that count-based service.
- 95937NMJ testing
- 95937 evaluates neuromuscular transmission with nerve stimulation and related testing. Code 95933 instead evaluates the trigeminal-to-facial blink-reflex pathway.
- 95930Visual evoked potential
- 95930 evaluates visual pathway responses to visual stimulation. Code 95933 uses electrical stimulation of the supraorbital nerve and records eye-muscle reflex responses.
95933 billing questions
How is 95933 different from a nerve-conduction study code such as 95910?
95933 reports the electrically elicited blink-reflex evaluation with recordings from the eye muscles. Code 95910 is selected according to the number of nerve-conduction studies performed.
Can 95933 be reported with nerve-conduction studies on the same date?
Yes, when the blink-reflex study and the nerve-conduction studies are both performed and documented as distinct services. The nerve-conduction code is selected by its own study-count criteria.
When should modifier 26 or TC be used?
Use modifier 26 for the professional interpretation and modifier TC for the technical service. Report without either modifier when billing the global service.
What documentation supports 95933?
Document the stimulation and bilateral orbicularis oculi recordings, the responses obtained, and the interpretation relevant to the suspected trigeminal, facial, or brainstem pathway problem.
Does 95933 represent one side or both sides?
The blink-reflex study includes recordings from both sides. The service is not selected by counting each eye as a separate nerve-conduction study.
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.
