Description

Portable infusion pumps are small battery-driven devices which can be worn by the ambulatory patient (usually attached to a belt). These pumps are attached to a needle or a catheter and are designed to provide continuous and/or intermittent delivery of a given drug. The most common usages include the infusion of insulin, chemotherapeutic agents, antibiotics, or heparin.

Criteria

A portable external infusion pump and related supplies may be considered medically necessary for the administration of drugs if the following set of criteria are met:

• Parenteral administration of the drug in the home is reasonable and necessary; and
• An infusion pump is necessary to safely administer the drug; and
• The drug is administered by a prolonged infusion of at least 8 hours because of proven improved clinical efficacy; and
• The therapeutic regimen is proven or generally accepted to have significant advantages over intermittent bolus administration regimens or infusions lasting less than 8 hours; or
• The drug is administered by intermittent infusion (each episode of infusion lasting less than 8 hours) which does not require the member to return to the physician's office prior to the beginning of each infusion; and
• Systemic toxicity or adverse effects of the drug are unavoidable without infusing it at a strictly controlled rate as indicated in the Physicians Desk Reference, or the U.S. Pharmacopeia Drug Information.

Other usages of the portable infusion pump are covered if a medical review establishes the appropriateness of the therapy and of the prescribed pump for the individual patient.

Procedure Codes

An ambulatory electrical infusion pump, may be considered medically necessary when used for the administration of epoprostenol. Payment may be made for only one pump for administering epoprostenol and treprostinil. The supplier is responsible for ensuring that there is an appropriate and acceptable contingency plan to address any emergency situations or mechanical failures of the equipment. A second pump provided as a backup will be denied as not medically necessary.

Procedure Codes

All cannulas, needles, dressings and infusion supplies (excluding the insulin reservoir) related to continuous subcutaneous insulin infusion via external insulin infusion pump and the infusion sets and dressings related to subcutaneous immune globulin administration are limited to 1 unit of service per week, additional units will be denied as not medically necessary.

Procedure Codes

The pump refilling and maintenance and cost of the drug are payable in accordance with coverage outlined in the member's benefits. Payment for chemotherapy administration may not be made in addition to pump refilling and maintenance since the portable infusion pump is easily filled and maintained. Modifier 59 may be reported with a non-E/M service, to identify it as distinct or independent from other non-E/M services performed on the same day. When modifier 59 is reported, the patient’s records must support its use in accordance with CPT guidelines.
