Retired - Correct Coding Reminder - Duopa® (AbbVie)

Joint DME MAC Article

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. Duopa® enteral suspension is supplied as a single-use cassette. Each cassette contains 20 mg levodopa and 4.63 mg carbidopa (as 5 mg of the monohydrate) per mL of enteral suspension. Each cassette contains approximately 100 mL of suspension.  Per the manufacturer, the maximum recommended daily dose of Duopa® is 2000 mg of the levodopa component (i.e., one cassette per day) administered over 16 hours. At the end of the daily 16-hour infusion, patients will disconnect the pump from the PEG-J and take their night-time dose of oral immediate-release carbidopa-levodopa tablets.

The DME MACs have received questions about the proper unit of service (UOS) to bill for Duopa®.  For dates of service on or after January 09, 2015 through December 31, 2015, claims for Duopa® must be submitted using the DME miscellaneous code J7799 (NOC DRUGS, OTHER THAN INHALATION DRUGS, ADMINISTERED THROUGH DME). When billing J7799, one (1) unit of service (UOS) is one cassette.

A unique HCPCS code was created for Duopa® with claims for dates of service on or after January 01, 2016.  The new code is:


The UOS for code J7340 is the same UOS used previously with the miscellaneous code J7799.  When billing code J7340, one (1) UOS = 100 ml. (1 cassette).  The HCPCS narrative will be revised in an upcoming HCPCS coding update.
