Summary & Overview
CPT 80371: Detection of Synthetic Stimulants (Bath Salts)
CPT code 80371 describes a laboratory assay that detects or quantifies synthetic stimulants ("bath salts") in patient specimens. This code is used for toxicology testing that identifies designer cathinones and related recreational stimulants that cross the blood-brain barrier and produce stimulant and euphoric effects. Nationally, such testing matters for emergency care, behavioral health evaluations, workplace safety investigations, and forensic and public health surveillance.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of the clinical context for testing, expected sites of service, and typical use cases. The publication also summarizes available coverage patterns, common modifiers associated with lab services, and benchmarking where available. Policy and coding updates relevant to laboratory toxicology testing are outlined, along with practical notes on documentation and claims processing considerations. Data not available in the input is identified where applicable.
Billing Code Overview
CPT code 80371 represents a laboratory test in which a clinical lab analyst measures the amount of, or detects the presence of, synthetic stimulants (commonly referred to as "bath salts") in a patient specimen. These synthetic stimulants are recreational drugs that cross the blood-brain barrier and stimulate intense feelings of excitement and euphoria.
-
Service type: Toxicology/bioanalytical drug detection
-
Typical site of service: Clinical laboratory or hospital laboratory with specimen collection occurring in outpatient clinics, emergency departments, inpatient units, or forensic/toxicology collection sites

Clinical & Coding Specifications
Clinical Context
A patient presents to the emergency department or outpatient clinic with acute agitation, altered mental status, tachycardia, hypertension, diaphoresis, or suspected intoxication after reported recreational drug use. The treating clinician orders a toxicology panel targeted to synthetic stimulants (commonly called "bath salts") to identify cathinone derivatives and related synthetic stimulants in blood or urine. A phlebotomy or urine collection is performed, the specimen is sent to the clinical laboratory, and the laboratory analyst performs qualitative or quantitative testing using immunoassay screening followed by confirmatory testing (e.g., GC-MS or LC-MS/MS) as needed. Results are reported to the ordering clinician to guide acute management, disposition, and any required public health or forensic documentation. Typical sites of service include hospital inpatient and emergency departments, hospital outpatient laboratories, and independent clinical toxicology laboratories.
