Summary & Overview
HCPCS Level II J1562: Immune Globulin (Vivaglobin) Injection, 100 mg
HCPCS Level II code J1562 identifies a 100 mg injection of immune globulin (Vivaglobin). This code is used when documenting and billing for subcutaneous or intramuscular immune globulin preparations provided as replacement or supplemental therapy for patients with antibody deficiencies or other qualifying immune conditions. Nationally, accurate coding of immune globulin products matters because these biologic therapies carry high unit costs and require precise itemization for coverage determinations, medical necessity review, and inventory control.
Key payers addressed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for immune globulin administration, the typical sites of service where J1562 is used, and what to expect from payer coverage patterns. The publication summarizes reimbursement benchmarks, common billing modifiers encountered in claims, and policy drivers that influence prior authorization and coverage criteria for immune globulin products.
The piece also highlights practical considerations for billing teams and revenue cycle managers, including unit reporting, documentation elements that support medical necessity, and typical payer communications. Data not available in the input is noted where applicable.

Clinical & Coding Specifications
Clinical Context
A 28-year-old adult patient with primary humoral immunodeficiency presents to an infusion clinic for subcutaneous immune globulin replacement using Vivaglobin. The patient arrives after telephonic triage confirming no active infections and stable vitals. A registered nurse verifies identity, reviews allergy history, obtains baseline vitals, and inspects prior infusion site. The prescribed dose is calculated in milligrams based on weight and ordered as J1562 units (100 mg per billing unit) with the total number of units documented on the medication administration record. The nurse prepares the subcutaneous infusion supplies, programs a small-volume pump or sets up manual push/infusion as per facility protocol, and performs aseptic technique to insert subcutaneous catheters into one or more infusion sites. The patient is observed for infusion-related reactions for at least 30–60 minutes after infusion start and monitored until vital signs are stable. The clinical workflow includes medication verification, documentation of lot number and expiration, administration time, number of J1562 units administered, site(s) used, and any adverse events. Billing captures the J1562 HCPCS Level II code per 100 mg unit, appropriate place of service (typically outpatient infusion center or physician office), and any applicable modifiers to reflect unusual circumstances such as increased procedural services or patient status.
