Summary & Overview
HCPCS E0455: Oxygen Tent, Whole-Body Oxygen Therapy
HCPCS Level II code E0455 identifies an oxygen tent (excluding croup or pediatric tents), a durable medical equipment item that provides a whole-body oxygen-enriched environment. Nationally, this code matters for hospital and facility billing where enclosed oxygen therapy is used as an alternative to mask- or cannula-based delivery. Clear coding affects device tracking, facility charge capture, and payer coverage determinations.
Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find national benchmarks for utilization and reimbursement patterns where available, an explanation of clinical contexts in which an oxygen tent is used, and considerations for facility-based billing workflows. The publication summarizes common modifiers and administrative details provided in the input and flags when specific data elements are not available.
This report provides a concise reference for coding staff, revenue cycle managers, and clinical leaders seeking to understand the purpose of E0455, the typical sites of service, and the payer landscape relevant to whole-body oxygen delivery devices in facility settings.
Billing Code Overview
HCPCS Level II code E0455 describes an oxygen tent, excluding croup or pediatric tents. The item is a durable medical device used to provide an oxygen-enriched environment for patients who require supplemental oxygen delivered to the whole-body enclosure rather than via mask or nasal cannula.
Service type: Durable medical equipment (oxygen delivery device)
Typical site of service: Hospital inpatient, hospital outpatient, or other facility-based settings where whole-body oxygen therapy is indicated
Data not available in the input.
Clinical & Coding Specifications
Clinical Context
A typical patient is an adult with acute hypoxemic respiratory failure due to pneumonia who requires a controlled-environment supplemental oxygen delivery method but does not need invasive ventilation. The patient arrives to the hospital emergency department with tachypnea, oxygen saturation in the low 80s on room air, and chest radiograph consistent with lobar consolidation. After initial assessment, the care team orders supplemental oxygen and determines that an oxygen tent is appropriate when localized delivery around the torso/head is preferred for more uniform oxygen concentration, or when other interfaces (nasal cannula, face mask) are not tolerated or contraindicated. The oxygen tent is set up at the bedside in an inpatient ward or observation unit; respiratory therapy assembles the tent, connects an oxygen source and flowmeter, monitors oxygen concentration and patient comfort, and documents device setup, oxygen flow, and patient response. The attending physician documents the indication, expected duration, and objectives (improve SpO2, reduce work of breathing). Nursing monitors skin integrity, mental status, and vital signs while respiratory therapy adjusts settings per protocol. Typical duration ranges from hours to days with periodic reassessment and weaning to lower-flow devices as clinically appropriate.
