Length of Approvals.
(1) A prior authorization approval shall be valid for the lesser of six (6) months after the date the
health care professional or provider receives the prior authorization approval or the length of
treatment as determined by the patient’s health care professional or the renewal of the policy or
plan, and the approval period shall be effective regardless of any changes, including any changes
in dosage for a prescription drug prescribed by the health care professional. Notwithstanding the
foregoing, a health insurer and an enrollee or his/her health care professional may extend a prior
authorization approval for a longer period by agreement. All dosage increases must be based on
established evidentiary standards, and nothing in this section shall prohibit a health insurance
issuer from having safety edits in place. This provision shall not apply to the prescription of
benzodiazepines or Schedule II narcotic drugs, such as opioids.
(2) Nothing in this provision shall require a policy or plan to cover any care, treatment, or
services for any health condition that the terms of coverage otherwise completely exclude from
the policy’s or plan’s covered benefits without regard for whether the care, treatment or services
are medically necessary.
