Neurology & Pain Management Coding Alert
Know Other EV Test Types to Master Coding Category
Do you know the code for a ‘blink reflex’ EP test? When your provider performs an evoked potential (EP) study, they could be testing for a number of neurological conditions. Last month, we examined how to code short-latency and central motor EP studies. This month, we take a look at the other three types of EP tests and how to code for them, with the help of Amy Pritchett, CCS, CPC-I, CPMA, CDEO, CASCC, CANPC, CRC, CDEC, CMPM, C-AHI, senior consultant at Pinnacle Enterprise Risk Consulting Services LLC in Centennial, Colorado. Check out this trio of EP study codes, along with a few of the diagnoses coders might be dealing with when your provider performs the tests for these patients. See 95930 for Visual EP If your provider performs a test using checkerboard or flash testing, they’re probably performing a visual EP study, which you’d report with 95930 (Visual evoked potential (VEP) checkerboard or flash testing, central nervous system except glaucoma, with interpretation and report). During 95930 service. “the provider performs a visual evoked potential testing that will measure the electric activity of the brain when responding to visual stimulus,” explains Pritchett. ICD-10 codes: Some of the conditions that your provider might be treating or diagnosing during a visual EP study include, but are not limited to: Use 95933 for ‘Blink Reflex’ Another EP study your provider could perform is the orbicularis oculi reflex, or “blink reflex,” test. Report this study with 95933 (Orbicularis oculi (blink) reflex, by electrodiagnostic testing). During 95933 service, the provider performs an electrodiagnostic test of the blink reflex. Blink reflex “is the involuntary blinking of the eyelids due to contraction of the orbicularis oculi muscles tapping the margin of the orbit or the bridge of the nose,” reports Pritchett. ICD-10 codes: Some of the conditions that your provider might be treating or diagnosing during a blink reflex EP study include, but are not limited to: Junction Testing Calls for 95937 Another EP study you provider might perform is a neuromuscular junction test. During this service, “the provider performs neuromuscular junction testing by repetitively stimulating nerves supplying the muscle to diagnose a patient with a known or suspected disorder of the neuromuscular junction,” says Pritchett. Report neuromuscular junction EP studies with 95937 (Neuromuscular junction testing (repetitive stimulation, paired stimuli), each nerve, any 1 method). ICD-10 codes: Some of the conditions that your provider might be treating or diagnosing during a neuromuscular junction EP study include, but are not limited to:
