Summary & Overview
CPT 36405: Scalp Vein Venipuncture for Patients Under Three Years
CPT code 36405 identifies percutaneous venipuncture of a scalp vein in patients under three years of age for blood collection or medication administration. This pediatric vascular access code matters nationally because it captures a specialized procedure used in neonatal and infant care where peripheral limb access may be limited; appropriate coding affects clinical documentation, claims processing, and pediatric care workflows. Key payers included in this analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical context for scalp vein access in young children, common payer coverage considerations, and what elements typically appear in claims lines for this service. The publication also outlines available benchmarks and policy-relevant notes where data exists and flags areas where information is not provided. Data not available in the input is explicitly noted. The goal is to equip coding professionals, pediatric clinicians, and billing managers with a clear, national-level reference for recognizing and documenting CPT code 36405 in relevant care settings.
Billing Code Overview
CPT code 36405 describes percutaneous venipuncture of a scalp vein in a patient younger than three years for the purpose of obtaining a blood sample or administering medication. This procedure is typically performed when peripheral access in the scalp is clinically preferred or required due to patient age, vein accessibility, or medical condition.
-
Service type: Vascular access procedure for blood draw or drug injection
-
Typical site of service: Inpatient or outpatient acute care settings, emergency department, or pediatric clinic where infant or toddler venous access is required
Clinical & Coding Specifications
Clinical Context
A typical scenario involves an infant or toddler (under three years old) presenting to the emergency department, pediatric clinic, or inpatient pediatric unit requiring venous access in the scalp for blood sampling or medication administration. Indications include difficult peripheral access due to dehydration, small or collapsed peripheral veins, severe illness, or when rapid laboratory results or drug delivery are required. The clinician (pediatrician, emergency physician, or pediatric nurse practitioner) explains the procedure to the parent or guardian, obtains consent, and prepares age-appropriate comfort measures (swaddling, sucrose, topical anesthetic if appropriate). The scalp is positioned and stabilized, cleaned with antiseptic, and a fine-gauge needle is inserted into a scalp vein to aspirate blood or deliver medication. Hemostasis is achieved with gentle pressure and a small dressing. Specimens are labeled and sent to the lab; medications are documented in the medical record. Documentation includes patient age, indication, site (scalp), needle gauge, amount and type of blood drawn or medication administered, any complications, and the provider performing the procedure.
