Smoking Cessation Program

STSIG is happy to offer this Wellness Program Benefit: FREE Smoking Cessation Aids. Your health is very important to us and we all know how smoking affects our health: shortness of breath, coughing, impairment of taste and smell, and most concerning of all, CANCER. We would like to help you stop smoking. Therefore, each member may receive smoking cessation products limited to 6 months per calendar year. These products include over-the-counter aids as well as prescription aids as follows:

  • Over-the-counter nicotine replacement agents: Gum, lozenges, patches
  • Prescription medication: Examples include prescription drugs such as Chantix, Inhalers, and Nasal Sprays. To obtain products at no cost, a prescription must be written by an in-network physician regardless if the product is a prescription medication or over-the-counter aid. The prescription may be taken to a Navitus participating pharmacy where the products can be purchased using the member's Navitus ID card with no copayment or out-of-pocket cost, as long as the member has not already met or exceeded their calendar year maximum.

Smoking Cessation Education Programs are strongly recommended, but not required to obtain medication. Recommended programs are through Mercy Medical Center.
