Summary & Overview
HCPCS Level II S4024: Air Polymer-Type A Intrauterine Foam, Per Study Dose
HCPCS Level II code S4024 denotes an air polymer-type A intrauterine foam supplied per study dose. This code identifies a specific intrauterine foam product used during uterine diagnostic or therapeutic procedures and is relevant for facility and professional billing where such study doses are administered. Nationwide, precise coding for single-use intrauterine supplies affects claim adjudication, inventory reporting, and aggregated utilization tracking for both public and commercial payers.
Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the code’s clinical context and service settings, common billing considerations, and typical sites of service. The publication also summarizes benchmark information and policy considerations affecting coverage and reimbursement for intrauterine study supplies, highlights documentation elements tied to correct code use, and points to related coding areas for procedural and supply reporting.
This overview is intended for coding professionals, billing managers, and clinical administrators responsible for accurate charge capture and claims submission for intrauterine study supplies in ambulatory and hospital outpatient settings.

Clinical & Coding Specifications
Clinical Context
A thirty-two-year-old reproductive-age patient presents to an outpatient gynecology clinic for evaluation of abnormal uterine bleeding refractory to medical therapy. The clinician elects to perform an intrauterine study using an air polymer-type A intrauterine foam to assess uterine cavity contour and identify focal lesions (for example, submucosal fibroids or polyps) prior to planning definitive therapy. The procedure is performed in an ambulatory procedure room or radiology suite under sterile conditions. After informed consent, a speculum is placed, the cervix is cleansed and stabilized with a tenaculum, and a small-diameter intrauterine catheter is introduced. The air polymer-type A foam is instilled as a single study dose while the clinician obtains real-time imaging (sonohysterography or fluoroscopy) to visualize uterine cavity filling and identify abnormalities. Vital signs are monitored before, during, and after the study. Post-procedure, the patient is observed briefly for pain or vasovagal symptoms, given discharge instructions regarding signs of infection or heavy bleeding, and the findings are documented in the medical record with images added to the chart. Typical site of service is an outpatient gynecology clinic, ambulatory surgery center, or radiology/imaging suite. Service type: intrauterine diagnostic contrast instillation for cavity evaluation (one study dose).
