Insurance giant Cigna says it will no longer cover most OxyContin prescriptions starting in 2018.

The company says it’s an attempt to reduce opioid use amid a nationwide abuse epidemic.

In a statement released Wednesday, Cigna Chief Pharmacy Officer Jon Maesner said, “Our focus is on helping customers get the most value from their medications — this means obtaining effective pain relief while also guarding against opioid misuse.”

Cigna is taking a multi-faceted approach to reduce opioid use by 25% by 2019.

The company is in the process of notifying customers with current OxyContin prescriptions and their doctors of the upcoming change.

OxyContin is a brand name for an extended-release version of oxycodone, a commonly prescribed opioid painkiller.

Cigna says they will consider approving coverage for OxyContin if a customer’s doctor feels that OxyContin is medically necessary.

Instead of OxyContin, Cigna says they are asking opioid manufacturers to align with efforts to reduce opioid use and has signed a value-based contract with Collegium Pharmaceutical for the drug Xtampza ER, an oxycodone equivalent with abuse-deterrent properties.
