Colorado Senate requires parity for clinically appropriate non‑opioid pain drugs in insurance coverage

The Colorado Senate on April 17 adopted Senate Bill 6, which requires health insurance plans to ensure at least one clinically appropriate non‑opioid prescription medication is available as an alternative to each opioid prescription and to limit barriers such as prior authorization and step therapy.

Sponsor Senator Amabile said the bill is intended to expand safer choices and reduce opioid harms. "This bill...says that every health insurance provider has to have at least one non‑opioid pain medication that they offer," she said, adding that manufacturers are producing non‑addictive options and patients need access to them.

Supporters, including Senator Kirkmeyer, argued the measure is about choice, not limiting access to opioids. "It's about more options, not fewer," she said. Proponents noted an actuarial estimate they cited showing the bill would cost under $5 per member per year (about 46 cents per member per month) once market competition develops.

Several senators spoke against immediately mandating coverage of new, often costly drugs. Senator Mullica, who said she works in an emergency room, argued many non‑opioid alternatives already exist and are affordable, such as Toradol, gabapentin and ketamine, and that mandating newer drugs could raise insurance costs. "We're mandating new expensive drugs when we have drugs on the market that are less expensive that can do the same job," she said.

Sponsors and other supporters countered that non‑opioid treatments frequently face greater administrative barriers than opioids, limiting patient access. "All we're asking for is those options to be treated the same as opioids," Senator Kirkmeyer said. Senator Amabile also noted the bill excludes Medicaid from the current version to reduce the fiscal impact on the state budget.

After floor debate and adoption of committee amendments, the motion to adopt Senate Bill 6 was approved by the chamber and the bill was passed on the floor for final consideration.

The next procedural step is final passage on the third reading and enrollment for transmittal to the House (the committee ordered SB6 engrossed and placed on the calendar for third reading and final passage).
