Four axes from current statute and agency guidance. Teal bar = substitution/assistance/access in place; amber = permissive or absent.
| Generic substitution mandate | Permissive |
| State Pharmaceutical Assistance Program | No broad SPAP |
| 90-day fills permitted | Allowed |
| PMP mandatory prescriber query | Required by statute |
Colorado permits but does not mandate generic substitution. Under C.R.S. § 12-280-130, a pharmacist may substitute a less expensive equivalent product unless the prescriber writes "dispense as written" or has otherwise prohibited substitution. The substitute must be FDA-approved as therapeutically equivalent. Patient consent is required.
Health First Colorado (Colorado Medicaid) maintains the Colorado Medicaid Preferred Drug List administered by the Department of Health Care Policy and Financing (HCPF). Most pharmacy benefits are fee-for-service. Non-preferred drugs require prior authorization initiated by the prescriber.

Prior authorization contact: Health First Colorado Pharmacy: 1-800-365-4944
Colorado does not operate a Medicare-recognized SPAP. Low-income Coloradans use Medicare Part D Extra Help (LIS), Health First Colorado (Medicaid) if eligible, manufacturer Patient Assistance Programs, and the SHIP program for Medicare enrollment counseling.
Eligibility: No active SPAP. Use federal Extra Help, Health First Colorado, and SHIP.
Colorado permits 90-day fills of non-controlled chronic medications. Out-of-state pharmacies must hold a Colorado Nonresident Pharmacy registration. Colorado requires e-prescribing for controlled substances under HB 21-1276. Federal CSA refill limits apply.
Colorado operates a Prescription Drug Monitoring Program administered by the Department of Regulatory Agencies. Under C.R.S. § 12-280-403, prescribers must check the PDMP before issuing the first prescription of an opioid or benzodiazepine. Dispensers must report Schedule II-V dispensing within one business day.
