Summary & Overview
CPT 82383: Blood Catecholamines Panel
CPT code 82383 represents a laboratory assay for measuring blood catecholamines — specifically epinephrine, norepinephrine, and dopamine. Nationally, this test is used in diagnostic evaluation of suspected catecholamine-secreting tumors, autonomic disorders, and select endocrine or metabolic conditions where catecholamine levels inform clinical management. Accurate billing and coding for this assay affects laboratory reimbursement, utilization tracking, and diagnostic workflows across outpatient and hospital settings.
Key payers referenced in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise view of coverage considerations and common billing practices among major payers, benchmark-level reimbursement context where available, and clinical context that clarifies appropriate use cases for the assay. The publication highlights how the test is typically ordered and performed in clinical laboratories and hospital outpatient labs, and outlines the operational implications for laboratories and providers handling these specimens.
This document does not provide patient-specific clinical guidance or recommendations; it focuses on coding, payer coverage landscape, and clinical context relevant to CPT code 82383. Data not available in the input will be noted where applicable.
Billing Code Overview
CPT code 82383 measures blood catecholamine levels, including epinephrine, norepinephrine, and dopamine. This laboratory test quantifies circulating catecholamines to evaluate biochemical markers related to autonomic function, suspected catecholamine-secreting tumors, or other metabolic and endocrine conditions.
Service Type: Clinical laboratory assay
Typical Site of Service: Clinical laboratory or hospital outpatient laboratory
Clinical & Coding Specifications
Clinical Context
A middle-aged adult presents to an outpatient endocrinology clinic with episodic headaches, palpitations, diaphoresis, and hypertension refractory to standard therapy. The clinician suspects a catecholamine-secreting tumor (pheochromocytoma/paraganglioma) or evaluates for autonomic dysfunction and orders a plasma or urine catecholamine panel. Blood is drawn under controlled conditions (patient rested, supine or seated per laboratory protocol) and sent to the laboratory for quantitative measurement of epinephrine, norepinephrine, and dopamine. Results guide further imaging (CT/MRI or functional scans) and preoperative management if a tumor is confirmed. Typical site of service is an outpatient laboratory or clinic with final analysis performed in a hospital or reference laboratory; inpatient measurement may occur when acute autonomic crises or critical care monitoring necessitate testing.

|---|---|---|
26 | Professional component | Use when billing only the physician interpretation component separate from the technical laboratory work |
TC | Technical component | Use when billing only the laboratory technical component (equipment, technicians, reagents) |
