CPT 36410: Venipuncture for Blood Draw or Infusion, Age 3+
CPT code 36410 identifies a common vascular access procedure — needle venipuncture for blood withdrawal or infusion in patients aged three years and older. Nationally, this code represents one of the most frequently billed basic technical procedures across outpatient and inpatient settings because it underpins routine laboratory testing and intravenous therapy delivery. Its prevalence affects resource planning, laboratory throughput, and billing workflows.
Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical context for CPT code 36410, typical sites of service, and the kinds of benchmarks and policy details usually associated with procedural billing codes of this type. The publication outlines common billing considerations, payer coverage patterns, and coding documentation expectations tied to routine venipuncture and infusion services. It also summarizes where variations typically arise — for example, when bundled into other services or billed with additional procedures — and highlights areas where policy updates or payer-specific rules commonly affect reimbursement.
This summary is written for a national audience of clinicians, coders, and policy analysts seeking a focused briefing on the role of CPT code 36410 in clinical practice and claims processing.

Clinical Context
A typical scenario involves a medically stable outpatient aged three years or older who requires venous access for diagnostic or therapeutic purposes. For example, a 45-year-old patient presents to an ambulatory clinic for routine laboratory testing ordered for metabolic panel and hemoglobin A1c. The clinical workflow begins with registration and verification of orders, confirmation of patient identity and consent, review of contraindications (eg, anticoagulation, history of difficult venous access), and preparation of supplies. A trained nurse or phlebotomist (or other qualified clinician) selects an appropriate peripheral vein, cleans the site with antiseptic, applies a tourniquet, inserts a sterile needle or butterfly device into the vein, and withdraws the required blood volume into collection tubes. If the procedure is for infusion rather than blood draw, the clinician attaches tubing and initiates the prescribed medication or IV fluids. Post-procedure care includes applying pressure or a dressing, documenting the number of attempts, patient tolerance, and any complications (hematoma, syncope), and labeling specimens per facility policy. This procedure is commonly performed in primary care clinics, outpatient laboratory centers, emergency departments, and inpatient medical-surgical units.
