SB1672: Rules for Antipsychotic Drug Coverage in AHCCCS

Starting January 1, 2027, this law stops Arizona's Medicaid program from requiring prior approval for antipsychotic drugs and limits step therapy rules to no more than two drug trials.

What This Bill Does

  • Prohibits AHCCCS and its contractors from using prior authorization requirements that delay or deny access to approved antipsychotic drugs.
  • Limits step therapy protocols so members must try no more than two distinct prescription antipsychotic drugs before switching options.
  • Allows members or providers to skip the step therapy process by showing proof of failure with two previous drugs on current or past plans.
  • Requires any drug review processes to be handled electronically and in real time.
  • Counts a member as having tried two drugs if they have paid claims for two distinct preferred antipsychotics within the last five years.

Who It Names or Affects

  • AHCCCS members who are at least 18 years old with a serious mental illness determination.
  • Health care providers prescribing medication to these AHCCCS members.
  • Contractors and managed care organizations that provide pharmaceutical services under AHCCCS.

Terms To Know

Prior authorization
A process where a health plan must approve a drug before it will pay for it, which can delay or deny delivery.
Step therapy protocol
A rule that requires patients to try specific lower-cost drugs first before the insurer covers other options.
Seriously mentally ill
Persons whose mental disorder causes severe impairment in daily activities like self-care, employment, or relationships.

Limits and Unknowns

  • The law only applies to antipsychotic drugs supported by peer-reviewed, evidence-based literature.
  • AHCCCS may still perform drug utilization reviews for patient safety and ensure prescriptions are medically accepted.
  • The effective date is January 1, 2027.

Amendments

These notes stay tied to the official amendment files and metadata from the legislature.

Plain English: This amendment creates new rules for AHCCCS to limit how they delay or deny coverage of antipsychotic drugs for adults with serious mental illness.

  • AHCCCS cannot require prior authorization that delays getting the drug, except by using a step therapy process.
  • Step therapy can only be used if the patient has failed to respond successfully to no more than two different antipsychotic drugs.
  • Patients or doctors can skip the step therapy requirement immediately if they provide proof of failing on two previous distinct drugs from any health plan.
  • Any approval process for these drugs must happen electronically and in real time.
  • The rules only apply to antipsychotic drugs approved by the FDA that are supported by peer-reviewed, evidence-based literature.
  • This law does not take effect until December 31, 2026.
  • AHCCCS can still perform drug reviews necessary for patient safety or to ensure the medication is used correctly.

Plain English: This amendment creates new rules for Arizona's AHCCCS program to limit how coverage can be delayed or denied for antipsychotic drugs prescribed to adults with serious mental illness.

  • AHCCCS cannot require prior authorization that delays getting the drug, except by using a step therapy process where patients must try up to two other distinct antipsychotic medications first.
  • Patients can skip trying new medications if they provide proof from their medical history showing they already failed to respond successfully to two different antipsychotic drugs on any current or past health plan.
  • Any required medication trial steps must be decided electronically and in real time, counting a patient as having tried the drug if they have paid claims for it within the last five years.
  • The rules only apply to antipsychotic drugs supported by peer-reviewed evidence-based literature.
  • This amendment does not take effect until December 31, 2026.
  • AHCCCS can still perform drug safety reviews or require generic versions of the medication.

Plain English: This amendment clarifies that the new rules for antipsychotic drug coverage do not stop Arizona's health system from collecting money back from drug companies or making special deals to lower costs.

  • The bill now states it does not block the state from getting federal rebates (money returned) from drug manufacturers under existing Medicaid programs.
  • The bill allows the state to sign new contracts with drug makers that offer extra discounts in exchange for placing their drugs on a preferred list.
  • The provided text cuts off at the end of Section G, so some definitions and details about health care providers are incomplete.
  • This explanation only covers the specific changes made by this amendment regarding rebates and contracts; it does not explain all other rules in the full bill.

FACT SHEET FOR
s.b. 1672

AHCCCS; antipsychotic drugs; authorization

Purpose

Effective January 1, 2027, prohibits
the Arizona Health Care Cost Containment System (AHCCCS) and its contractors
from requiring prior authorization for prescription antipsychotic drugs and
limits any step therapy protocols to no more than two distinct prescription
antipsychotic drugs.

Background

AHCCCS serves as Arizona's Medicaid agency, which offers Arizona
residents access to healthcare programs. AHCCCS contracts with health
professionals to provide medically necessary health and medical services to
eligible members. Additionally, AHCCCS must contract for a coordinated system
of behavioral health services for persons deemed seriously mentally ill,
including screening and intake, case management, treatment planning family
involvement and a continuum of care (A.R.S. ��
36-2901

and
36-3407
).

Seriously mentally ill
means persons who, as a result of a mental
disorder, exhibit emotional or behavioral functioning that is so impaired as to
interfere substantially with their capacity to remain in the community without
supportive treatment or services of a long-term or indefinite duration. In
these persons, mental disability is severe and persistent, resulting in a

long-term limitation of their functional capacities for primary activities of
daily living such as interpersonal relationships, homemaking, self-care,
employment and recreation (
A.R.S.
� 36-550
)

Step therapy protocol
is a protocol or program that establishes
the specific sequence in which prescription drugs that are for a specified
medical condition and that are medically necessary for a particular patient are
covered by a health care insurer under a health care plan (
A.R.S.

� 20-3651
).

The Joint Legislative Budget Committee (JLBC) estimates that S.B. 1672
would increase state General Fund costs by between $27,000,000 and $120,000,000
annually, due to the approval of prior authorization requests that would
previously have been denied and members switching from low-cost generic drugs
to high-cost brand name drugs (
JLBC
fiscal note
).

Provisions

1.

Specifies
that, before providing coverage of a prescription antipsychotic drug approved
by the U.S. Food and Drug Administration to a member who is at least 18 years
old with a serious mental illness, AHCCCS and its contractors:

a)

may not impose a prior authorization requirement or other process that
conditions, delays or denies the delivery of the drug to the member by applying
predetermined criteria by AHCCCS or its contractor for covered prescription
drugs, except as otherwise outlined; and

b)

may
impose a process, including a step therapy protocol, requiring the member to show
a failure to successfully respond to up to two distinct prescription
antipsychotic drugs.

2.

Requires AHCCCS and its contractors to allow a member, or the member's
health care provider, to bypass a step therapy protocol by submitting
documentation that the member failed to successfully respond to two distinct
prescription antipsychotic drugs on the member's current or previous health
benefit plan.

3.

Requires
any step therapy protocol or other process administered to:

a)

be adjudicated electronically and in real time; and

b)

consider
a member to have tried two prescription antipsychotic drugs if the member has
two paid claims for two distinct preferred antipsychotic drugs prescribed in a
nonemergency or outpatient setting within the previous five years.

4.

Specifies
that the antipsychotic drug coverage requirements:

a)

only apply to a prescription antipsychotic drug whose use is supported
by peer-reviewed, evidence-based literature;

b)

apply to prescription drug coverage that is paid either on a
fee-for-service basis or through a prepaid capitated health services contract
under AHCCCS;

c)

do not prohibit AHCCCS from contracting with a managed care organization
for pharmaceutical services offered under AHCCCS if the contract complies with
the outlined requirements;

d)

do not prohibit AHCCCS from prohibiting or discourage the use of a
generic drug;

e)

do not prevent AHCCCS from performing a drug utilization review that is

and

g)

do
not prohibit AHCCCS from entering into a supplemental rebate contract agreement
with a drug manufacturer for preferred placement on the preferred drug list.

5.

Defines
failure to successfully respond
as a determination, based
on clinically appropriate guidelines, that a patient has failed on a
medication, including a lack of efficacy during a

six-week medication trial, an allergic reaction, intolerable side effects,
significant drug-to-drug interactions or a known interacting genetic
polymorphism that prevents safe preferred medication dosing as attested to by
the patient's health care provider.

6.

Defines terms.

7.

Becomes effective on January 1, 2027.

Amendments Adopted by the
Appropriations, Transportation & Technology Committee

�

Limits qualifying antipsychotic drug claims for step-therapy
