Summary & Overview
CPT 0107T: Vibration Sensation Threshold Assessment
CPT code 0107T identifies a quantitative assessment of vibration sensation threshold performed on an extremity to evaluate and quantify large-fiber sensory function. This procedure supports diagnosis of peripheral nerve injury and neuropathies by comparing measured vibration thresholds to normative values. Nationally, services that objectively quantify sensory impairment inform clinical decision-making, disability evaluations, and targeted management of neuropathic conditions.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise description of the procedure, typical sites of service, and an overview of the clinical context in which the test is used. The publication also presents payer coverage considerations, common billing modifiers associated with the service, and related coding guidance where available. Policy updates and benchmark data are summarized when provided; where input data is missing, the report notes that information is not available in the input.
This analysis is intended for a national audience of clinicians, billing professionals, and policy analysts seeking a clear, factual summary of CPT code 0107T, its clinical purpose, and the payer landscape relevant to quantifying peripheral sensory function.
Billing Code Overview
CPT code 0107T describes an assessment in which a provider determines a patient’s vibration sensation threshold by stimulating the skin of an extremity and comparing the results to normal values. The service quantifies sensory function of an extremity to help diagnose damage to large nerve endings.
-
Service type: Sensory nerve function testing (quantitative vibration threshold assessment)
-
Typical site of service: Outpatient clinic or specialty neurology/physical medicine setting where peripheral nerve function testing is performed

Clinical & Coding Specifications
Clinical Context
A 58-year-old patient with a history of type 2 diabetes and progressive numbness in the feet is referred to a neurology clinic to quantify large-fiber sensory loss. The provider performs a vibration sensation threshold test on the dorsal surface of the great toe and the medial malleolus using a calibrated vibrator. Results are compared to age- and sex-adjusted normal values and documented in the clinic note, including test sites, patient cooperation, threshold values, and interpretation. The procedure is typically ordered to evaluate suspected peripheral neuropathy, monitor progression of known neuropathy, or assess nerve injury after trauma or surgical intervention. Typical sites of service include outpatient neurology clinics, physiatry or rehabilitation clinics, diabetes centers, and occasionally inpatient consultation settings. The clinical workflow includes review of history and prior exams, consenting the patient, performing the stimulation and recording numeric threshold or descriptive results, correlating findings with reflex and motor exam, and generating an assessment that contributes to diagnostic coding and care planning.
