Summary & Overview

HCPCS S9562: Home Injectable Therapy for Palivizumab/RSV Support

HCPCS Level II code S9562 designates a per diem package for home-based injectable therapy support related to palivizumab or other monoclonal antibodies for RSV, covering administrative services, professional pharmacy services, care coordination, and necessary supplies and equipment while drugs and nursing visits are billed separately. This code matters nationally as use of prophylactic monoclonal antibodies for RSV is an important component of outpatient pediatric and high-risk adult care pathways, and home-based administration reduces facility burden and exposure risk while requiring clear billing delineation between drug, nursing, and support services.

Key payers covered in this overview include Aetna, Blue Cross Blue Shield, Cigna, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the code's clinical and service context, how the code is used in home infusion and home health settings, and what elements S9562 is intended to capture versus separate billable components. The publication also outlines typical modifiers and payer considerations and summarizes where data is available or not. This national-focused summary is intended to help billing managers, pharmacy services, and payers recognize the administrative service component for home-administered monoclonal antibody prophylaxis for RSV and to understand how it fits alongside separately billed drug and nursing services.

Clinical & Coding Specifications

Clinical Context

A six-month-old former premature infant with chronic lung disease of prematurity is scheduled for home administration of palivizumab as RSV prophylaxis during RSV season. The infant’s pediatric pulmonologist orders monthly intramuscular injections of palivizumab. A specialty pharmacy coordinates medication dispensing and nursing visits. A home health RN visits the infant monthly to perform pre-administration assessment (vital signs, respiratory status, screening for recent fever or infection), verify informed consent, reconstitute and prepare the monoclonal antibody per manufacturer instructions, administer the intramuscular injection, monitor for immediate adverse reactions for at least 30 minutes, document lot numbers and administration in the medical record, and arrange follow-up care coordination. Nursing and drug acquisition/administration encounter charges are coded separately; S9562 is billed as the per diem for home injectable therapy program management, administrative and professional pharmacy services, care coordination, and necessary supplies and equipment supporting home palivizumab therapy.
