Summary & Overview
HCPCS C9803: Hospital Outpatient SARS-CoV-2 Specimen Collection
HCPCS Level II code C9803 designates specimen collection for SARS-CoV-2 (COVID-19) performed in a hospital outpatient clinic. This code standardizes billing for the act of collecting any specimen source for COVID-19 testing separate from the laboratory test itself. Nationally, specimen collection codes are important for differentiating facility-based collection services from testing and for aligning payment across outpatient clinic settings.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna, UnitedHealthcare, and Medicare. Readers will find an overview of the code's clinical scope and service setting, typical billing considerations, common modifiers used with this service, and how this code interacts with laboratory testing reconciliation. The publication also provides benchmarks and policy update summaries where available, plus practical notes on payer coverage patterns and claim adjudication considerations for hospital outpatient specimen collection.
This summary targets administrators, coding professionals, and policy analysts seeking a concise reference to C9803, its intended use, and the national payer context for hospital outpatient COVID-19 specimen collection services. Data not available in the input will be noted in relevant sections.

Clinical & Coding Specifications
Clinical Context
A symptomatic adult presents to a hospital outpatient clinic with fever, cough, or known exposure to SARS-CoV-2. The patient registers at the clinic reception, is triaged by nursing staff, and is escorted to an isolation room or designated collection area. A trained clinician or licensed phlebotomist obtains an appropriate specimen (nasopharyngeal swab, nasal swab, saliva, or other approved source) using standard infection-control precautions. Specimen labeling, ordering, and transport to the hospital laboratory or an external testing lab follow facility protocol. The visit is documented in the outpatient medical record, including indication for testing, specimen type, collector identity, and time of collection. Billing for the specimen collection in the hospital outpatient clinic is reported with C9803 and may be accompanied by visit-level or laboratory processing codes as clinically applicable.
