50 Ill. Adm. Code 2040.80
Access to Covered Prescription Drugs
Section 2040.80 Access to
Covered Prescription Drugs
This Section applies to
health insurance coverage that covers prescription drugs.
a) An issuer shall cover off-formulary
prescription drugs if there is not a formulary drug available to treat the
insured. The issuer shall do so without any prior authorization or step-therapy
requirements that are separate from or redundant to any requirements already
satisfied for the unavailable formulary drug. No greater cost-sharing shall be
imposed than would apply to the formulary drug. Group health insurance coverage
is subject to this subsection even if it is not provided by a health
maintenance organization.
b) To the extent consistent with clinical
guidelines, an issuer shall cover an insured to obtain at least a 90-day supply
upon refill of a covered maintenance medication, though exceptions may be made
for drug classes that are prone to misuse, such as opioids, benzodiazepines,
and stimulants. Group health insurance coverage is subject to this subsection
only if it is provided by a health maintenance organization.
