Revised January 7, 2016

This is a revision to a previous version published February 20, 2015, and adds the new HCPCS code for Duopa®.

On January 09, 2015, Duopa® (AbbVie) was approved by the FDA. Duopa® is an enteral-suspension combination of levodopa and carbidopa, and is indicated for the treatment of Parkinson's disease (PD). Duopa® is administered as a continuous 16-hour infusion into the jejunum through a percutaneous endoscopic gastrostomy-jejunal tube (PEG-J), using a CADD®-Legacy 1400 portable infusion pump.

The Durable Medical Equipment Medicare Administrative Contractors (DME MACs) have evaluated Duopa® and determined that it is eligible for inclusion in the Durable Medical Equipment (DME) External Infusion Pump Local Coverage Determination (LCD). Refer to the External Infusion Pump LCD and Policy Article for specific coverage requirements.

Suppliers are reminded that when submitting claims for items coded J7799, the supplier must include the following information on each claim:

  • Name of Drug
  • Dosage Strength
  • Amount Dispensed (e.g., total mg)
  • Administration Instructions

This information must be entered in the narrative field of an electronic claim (NTE 2300 or NTE 2400 of an electronic claim) or Item 19 of a paper claim.

Claims for Duopa® for dates of service on or after January 09, 2015, through December 31, 2015, must be submitted using the HCPCS code J7799 (NOC DRUGS, OTHER THAN INHALATION DRUGS, ADMINISTERED THROUGH DME).

Claims for Duopa® for dates of service on or after January 01, 2016, must be submitted using the HCPCS code J7340 (CARBIDOPA 5 MG/LEVODOPA 20 MG ENTERAL SUSPENSION).

Establishment of the transabdominal port with a PEG-J is performed under endoscopic guidance by a gastroenterologist or other healthcare provider experienced in this procedure. The PEG-J is considered a supply provided incident to a physician's service, and claims for this item are processed by the A/B MAC contractor. Claims to the DME MAC for the PEG-J will be rejected as wrong jurisdiction.

Refer to the, the External Infusion Pump LCD and related Policy Article for additional coverage, coding and documentation requirements.
