CPT® Code 80355

The CPT® Code 80355 refers to a laboratory test specifically designed to measure the levels of gabapentin in urine. Gabapentin, known by the brand name Neurontin, is classified as an anticonvulsant and analgesic medication. It is primarily utilized in the management of various medical conditions, including seizure disorders, neuropathic pain such as diabetic neuropathy and post-herpetic neuralgia, as well as restless leg syndrome. The testing process involves obtaining a urine sample, which can be collected through a random void or catheterization, both of which are separately reportable procedures. The analysis of the urine sample is conducted using advanced techniques such as quantitative high-performance liquid chromatography coupled with tandem mass spectrometry, ensuring precise measurement of gabapentin levels. This test is crucial for monitoring therapeutic levels of the drug, assessing compliance, and detecting potential misuse or abuse of the medication.
