HCPCS code E0570: Nebulizer, with Compressor

Learn how to use HCPCS code E0570 for nebulizers with compressors, including documentation, billing requirements, and applicable modifiers.

Use Code

## **What is a nebulizer with compressor?** HCPCS code E0570 refers to “Nebulizer, with compressor.” This code covers a small-volume nebulizer system that delivers inhalation medication by converting liquid drugs into an aerosol mist through compressed air. The compressor generates a fixed low-pressure air stream that passes through tubing to the nebulizer cup, enabling patients to inhale the medication via a mouthpiece or mask. E0570 is prescribed when aerosolized drug delivery is medically necessary and cannot be achieved effectively with other devices, such as a metered dose inhaler (MDI) or dry powder inhaler. Some patients cannot coordinate MDI use, and their condition necessitates nebulizer therapy, especially when medications are provided in unit-dose form or concentrated form that must be diluted and aerosolized. Clinically, E0570 is most often used for conditions such as asthma, chronic obstructive pulmonary disease (COPD), cystic fibrosis, or bronchiectasis, where nebulized medications like albuterol, ipratropium, dornase alfa, or the ability to administer treprostinil inhalation solution are indicated. Unlike a large-volume nebulizer or a small-volume ultrasonic nebulizer, which fall under different HCPCS codes, E0570 applies specifically to compressor-based systems, sometimes referred to as aerosol compressors. The device itself is classified as respiratory equipment under the durable medical equipment rules and is used to deliver FDA-approved final products via nebulization. Accessories can include a glass or autoclavable plastic bottle type chamber for specific medications, and patients must be trained in cleaning respiratory equipment to maintain safety and performance. Some payers also note the usual maximum frequency of use for supplies and drugs, which must be documented in the medical record.

## **E0570 documentation requirements** Clear documentation is necessary to establish medical necessity and to ensure correct coding. ### **Medical necessity and indications** Describe the patient’s respiratory diagnosis and the specific need for nebulized therapy. Common justifications include frequent bronchospasm, poor inspiratory flow that prevents proper inhaler use, or chronic conditions requiring inhaled medications only available in nebulized form. Explain how the nebulizer will enhance medication delivery, improve airway clearance, and promote patient safety. ### **Prescription and written order** A Standard Written Order (SWO) or equivalent prescription must be obtained before dispensing. The order should specify “nebulizer with compressor” or a narrative consistent with E0570, include the prescribed inhalation drug(s), frequency of use, and the intended duration of therapy. ### **Clinical evaluation and justification** Document the face-to-face or telehealth encounter showing that nebulizer therapy is required. Note if the patient cannot coordinate or tolerate inhaler use due to age, cognition, or disease severity. Include why alternatives such as inhalers with spacers are not appropriate. Equipment details and accessories Record the equipment provided, including compressor type, nebulizer cup, tubing, mouthpiece or mask, and any disposable filters. Indicate supply replacement schedules as needed. ### **Proof of delivery and follow-up** Maintain delivery documentation with device description, serial or lot number, and date received. Include patient training notes on cleaning, assembly, and medication administration. Schedule follow-up to assess effectiveness, tolerance, and compliance.

## **E0570 billing requirements** Bill E0570 accurately reflects the device provided and payer coverage rules. ### **Code selection and units** Report E0570 once per nebulizer system supplied. The code includes the compressor unit itself, but not replacement supplies or accessories, which may be billed separately under their own HCPCS codes. ### **Coverage and limitations** Coverage is tied to whether the prescribed inhalation drug is itself covered by the payer. If the drug is non-covered, the device and supplies are also denied. Check the Local Coverage Determination (LCD) and payer drug lists. ### **Rental vs purchase** Under Medicare, nebulizers billed as E0570 are generally treated as purchased items, not rentals. Private payers may vary; always verify payer policy. ### **Accessories and supplies** Supplies like tubing, nebulizer cups, masks, and filters are billed separately. Document frequency of use and medical necessity for replacement. Ensure billing matches supply limits set by payer policy. ### **Replacement and repairs** If replacement is needed due to loss, damage, or patient condition changes, follow payer requirements for replacement claims. If billing for a repair part, append the RB modifier when permitted.

## **E0570 applicable modifiers** Use modifiers to indicate coverage status and equipment type: - **NU**: New equipment purchase, used by many payers for durable medical equipment. - **GA**: Waiver of liability statement issued, patient notified of non-coverage. - **GZ**: Item expected to be denied, no waiver of liability obtained. - **RB**: Replacement of a part furnished as a repair, if applicable.

## **Other relevant codes** If E0570 is not the correct fit, consider these nearby HCPCS codes: - **E0565**: Compressor, air power source for equipment which is not self- contained or cylinder driven - **E0572**:Aerosol compressor, adjustable pressure, light duty for intermittent use - **E0574**: Ultrasonic/electronic aerosol generator with small volume nebulizer

Frequently asked questions

Under Medicare Part B, HCPCS code E0570 (Nebulizer, with compressor) is classified as Inexpensive or Routinely Purchased durable medical equipment (DME). This means it is reimbursed as a single lump-sum purchase rather than through recurring monthly rental payments.

Yes. Accessories like administration sets, masks, and filters are billed separately with their own HCPCS codes, adhering to documented medical necessity and allowed replacement frequency.

Coverage is allowed when administering FDA-approved inhaled medications via nebulizer for conditions such as obstructive pulmonary disease, cystic fibrosis, bronchiectasis, pneumocystosis in HIV, and transplant complications, as per LCD guidance.
