Summary & Overview
CPT 82600: Cyanide Assay in Clinical Laboratory
CPT code 82600 represents a laboratory toxicology assay used to measure cyanide in a patient specimen. This test is clinically important for the evaluation and management of suspected cyanide exposure or poisoning, which can be life-threatening and time-sensitive. Nationally, coding accuracy for toxicology assays affects clinical decision-making, laboratory billing, and emergency care workflows.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of what CPT code 82600 denotes, typical clinical contexts and sites of service, common billing modifiers associated with laboratory services, and where to look for reimbursement and coverage guidance. The publication also summarizes benchmark elements and policy considerations relevant to laboratory toxicology testing, regulatory and documentation expectations, and operational notes that affect claims processing. Data not available in the input is explicitly noted where applicable.
Billing Code Overview
CPT code 82600 describes a laboratory measurement of cyanide concentration in a patient specimen. The service involves analytical testing performed by a clinical laboratory or lab analyst to detect and quantify cyanide levels for clinical assessment of exposure or poisoning.
-
Service type: Clinical laboratory toxicology assay
-
Typical site of service: Hospital laboratory, independent clinical laboratory, or emergency department laboratory services
Clinical & Coding Specifications
Clinical Context
A typical patient is an adult presenting to the emergency department or toxicology service after suspected acute cyanide exposure from smoke inhalation in a house fire, industrial exposure, or ingestion of cyanogenic compounds. Initial clinical workflow includes triage and stabilization (airway, breathing, circulation), collection of blood (venous or arterial) and, when relevant, urine samples. The laboratory test 82600 is ordered to measure cyanide concentration to confirm exposure and help guide antidotal therapy (for example, hydroxocobalamin) and ongoing clinical management. Specimen handling requires rapid transport on ice or use of preservatives per laboratory protocol; results are prioritized and communicated urgently to the treating team. Typical sites of service are hospital emergency departments, inpatient hospital labs, and specialized toxicology laboratories. Clinicians ordering the test commonly include emergency medicine physicians, medical toxicologists, intensivists, and occupational medicine specialists.
