Author: CSRA

Effective with date of service March 8, 2018, the North Carolina Medicaid and N.C. Health Choice (NCHC) programs cover mometasone furoate sinus implant (Sinuva) for use in the Physician's Drug Program (PDP) when billed with HCPCS code J3490 - Unclassified drugs. One Sinuva Sinus Implant system contains 1350 mcg of mometasone furoate and a sterile delivery system.

Sinuva is indicated for the treatment of nasal polyps in patients 18 years of age and older who have had ethmoid sinus surgery. One Sinuva Sinus Implant contains 1350 mcg of mometasone furoate, which is loaded into a delivery system and placed in the ethmoid sinus under endoscopic visualization and left in the sinus to gradually release the corticosteroid over 90 days. It may be removed at day 90 or earlier at the physician's discretion. Repeat administration has not been studied.
