Summary & Overview
HCPCS E1353: Regulator for Durable Medical Equipment
HCPCS Level II code E1353 identifies a regulator, a category of durable medical equipment that controls or moderates a physiological device or therapy delivery system. Nationally, clear coding for device regulators influences claims adjudication, patient access to needed equipment, and uniformity in benefit administration across payers. This code matters for suppliers, billing professionals, and payers because accurate identification impacts coverage determinations and billing workflows.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the code's clinical and billing context, typical sites of service, and common modifiers used with HCPCS equipment codes. The publication outlines typical coverage landscapes and what to expect when submitting claims for device regulators, highlights common billing considerations, and points to related service lines where E1353 may appear.
The content is intended for a national audience of providers, suppliers, and reimbursement staff. It provides practical benchmarking and policy context without state-specific rules. Data not available in the input will be identified as such where applicable.

Clinical & Coding Specifications
Clinical Context
A 62-year-old patient with chronic obstructive pulmonary disease (COPD) and progressive hypoventilation is evaluated in an outpatient durable medical equipment clinic for long-term oxygen therapy and ventilatory support. A clinician identifies the need for an oxygen regulator to control flow from a stationary oxygen concentrator or compressed oxygen cylinder during home therapy. The patient presents with current prescriptions for supplemental oxygen and demonstrates inability to safely self-regulate flow settings due to dexterity limitations. The respiratory therapist assesses device compatibility, determines the regulator model required for the patient’s oxygen source, documents medical necessity, and arranges delivery and patient education.
Typical clinical workflow:
-
Referral from pulmonologist or primary care provider with order for home oxygen support and associated supplies.
-
Respiratory therapist evaluates patient’s oxygen delivery system, measures required flow range, and selects an appropriate regulator (billing code
E1353). -
Supplier obtains prior authorization if required, documents clinical indications (e.g., hypoxemia, COPD exacerbation history), and records supplier and clinician taxonomy and supplier invoice details.
-
Delivery to patient’s home with education on use, safety checks, and documentation of serial numbers and linkage to the oxygen source.
