## Definition
The HCPCS (Healthcare Common Procedure Coding System) code E0660 refers to “Non-segmental pneumatic compressor.” This device is commonly used to treat patients with lymphedema, chronic venous insufficiency, or other conditions characterized by chronic swelling or fluid retention. The non-segmental pneumatic compressor works by applying uniform pressure to the affected area to facilitate the drainage of lymphatic fluid or blood.
Unlike its segmental counterpart, the non-segmental device does not differentiate pressure across various parts of the limb, applying the same pressure throughout. It is typically used in home settings by patients who require consistent therapy. HCPCS E0660 is recognized under the Durable Medical Equipment (DME) category, often provided on a rental or purchase basis depending on the patient’s needs and insurance coverage.
## Clinical Context
The non-segmental pneumatic compressor is prescribed primarily for patients diagnosed with lymphedema, which may occur following surgery (such as mastectomy), injury, or as a congenital condition. It also serves as a treatment modality for chronic venous insufficiency, particularly when conservative measures, such as compression stockings, have proven inadequate.
The device is effective in reducing swelling, improving lymphatic drainage, and alleviating discomfort associated with chronic fluid retention in the limbs. In a clinical setting, pneumatic compression therapy is generally part of a comprehensive management plan, which could also involve manual lymphatic drainage, exercise, and skin care measures.
## Common Modifiers
Modifiers are often attached to E0660 claims to communicate specific details about the equipment or patient usage. One of the commonly used modifiers is the “RR,” which indicates that the device is being rented rather than purchased. This is important as rental agreements often include periodic payments as opposed to one-time purchases.
Another common modifier is the “NU,” signifying that the device is newly purchased. The “UE” modifier, which stands for “used equipment,” may also be applied when a refurbished device is provided to the patient. Including the appropriate modifier is crucial for the correct interpretation and processing of claims.
## Documentation Requirements
To fulfill the documentation requirements for E0660, it is essential that the prescribing physician provide a detailed order that includes the patient’s diagnosis and rationale for using a non-segmental pneumatic compressor. The clinical notes should indicate that the patient experiences chronic or intermittent swelling that has not improved with basic interventions like compression garments or wraps.
Additionally, the medical record must demonstrate that alternative treatments have been tried and deemed insufficient. Records should also document patient adherence and outline the frequency and duration of therapy. All documents must be signed, dated, and available upon request by the payer to support claims.
## Common Denial Reasons
One of the most frequent reasons for the denial of claims related to E0660 is insufficient medical necessity documentation. If a payer determines that the clinical evidence does not adequately justify the use of a non-segmental pneumatic compressor, particularly if conservative treatments were not previously attempted or documented as ineffective, denial is likely.
Another common reason for denial is the incorrect or incomplete use of billing modifiers. For instance, if a claim is submitted for a rented device without the “RR” modifier, or a purchased unit without the “NU” modifier, it will likely get rejected. Additionally, denials may occur due to the failure to prove the long-term use or continued benefit of the pneumatic compressor.
## Special Considerations for Commercial Insurers
Commercial insurers may impose more stringent criteria than Medicare or Medicaid for HCPCS code E0660. In some cases, they may require prior authorization before approving the use of the non-segmental pneumatic compressor. Patients may also need to meet more specific diagnostic criteria beyond broad definitions of lymphedema or chronic venous insufficiency to qualify for device coverage.
Additionally, some commercial insurers may only approve the device on a rental basis but may not cover the eventual purchase of the equipment. They may also limit the duration of rental agreements, making it important for healthcare providers and patients to understand the terms of coverage. Out-of-pocket costs, such as co-pays or deductibles, may also differ significantly based on the patient’s commercial insurance plan.
## Similar Codes
Several other HCPCS codes are closely related to E0660. For instance, HCPCS code E0650 represents a “pneumatic compressor, segmental,” which differs from the non-segmental version by applying varying levels of pressure across different segments of the limb. This segmental approach may be preferred in cases where more tailored compression is clinically indicated.
Another similar code is E0651, which refers specifically to a segmental pneumatic compressor with calibrated gradient pressure. This is a more advanced type of device that allows for the regulation of pressure at different points along the limb, providing a more customized treatment approach. HCPCS code E0665 is also related, as it is used for high-pressure, segmental pneumatic compressors intended for more severe conditions.
