HCPCS A4619: Face Tent Oxygen Delivery Device
HCPCS Level II code A4619 represents a face tent, an oxygen delivery device used to provide supplemental oxygen and humidity to patients when standard nasal cannula or masks are unsuitable. Nationally, supplies and accessories for oxygen delivery are important for acute respiratory care, procedural support, and inpatient respiratory management, making A4619 relevant to hospitals, emergency departments, and other clinical settings. 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 face tent use, typical sites of service, and the payer landscape. The publication provides benchmarks and billing considerations related to reimbursement and coverage policies across major commercial plans and Medicare, highlights coding relationships to other respiratory supply codes where applicable, and summarizes common modifier usage patterns when documented. This resource is designed to clarify what A4619 denotes, where it is commonly billed, and what billing teams and administrators should expect when processing claims for face tent supplies in a national context.

Clinical & Coding Specifications
Clinical Context
A 68-year-old male with chronic obstructive pulmonary disease (COPD) is admitted to a medical-surgical unit for acute hypoxemic respiratory distress after a community-acquired pneumonia diagnosis. The patient requires short-term supplemental oxygen delivery but is intolerant of a tight-fitting mask and does not require invasive ventilation. A disposable face tent is applied to provide low-to-moderate flow oxygen while allowing access for oral care and suctioning. Respiratory therapy documents device application, liter flow, oxygen concentration, patient tolerance, and reassesses respiratory rate and SpO2 at regular intervals. Nursing monitors skin integrity around the face, ensures device positioning, and documents device removal when therapy is discontinued.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
00 | No modifier — standard billing | Use when no special circumstance applies to the face tent supply. |
52 | Reduced services | Use when a lesser quantity or shorter duration of device use than typical is provided. |
