Plain English Breakdown

The official source material does not specify the exact content that needs to be posted by AHCCCS, only that it is required for certain decisions made by MCOs.

Behavioral Health Contracts and Network Adequacy

This bill requires MCOs in Arizona to provide advanced notice before terminating contracts with high-volume service providers, ensuring network adequacy is maintained.

What This Bill Does

  • Requires MCOs to give AHCCCS at least 90 days' written notice before ending a contract with a high-volume service provider without cause.
  • MCOs must include specific documentation and a network adequacy study in their notice, showing the impact of termination on service availability.
  • AHCCCS reviews the MCO's network adequacy study within ten business days to ensure standards are met after termination.
  • If AHCCCS finds that network adequacy will not be maintained, it can prevent the MCO from terminating the contract unless the MCO shows how standards will still be met.

Who It Names or Affects

  • Managed care organizations (MCOs) in Arizona
  • High-volume service providers who contract with MCOs
  • AHCCCS, which oversees Medicaid programs

Terms To Know

high-volume service provider
A service provider that delivered at least ten percent of a specific service for an MCO in the previous fiscal year or employs more than ten percent of actively licensed behavioral health providers in Arizona.
network adequacy study
An evaluation by an MCO showing how terminating a high-volume provider will affect access to services and care quality.

Limits and Unknowns

  • The bill's fiscal impact cannot be determined without additional information from AHCCCS.

ARIZONA STATE SENATE

Fifty-Seventh
Legislature, Second Regular Session

REVISED

AMENDED

FACT SHEET FOR
s.b. 1629

behavioral
health; contracts; network adequacy

Purpose

Requires managed
care organizations (MCOs) contracted with the Arizona Health Care Cost
Containment System (AHCCCS), including Arizona Long Term Care System (ALTCS)
program contractors and regional behavioral health authorities (RBHAs), to
provide written notice to AHCCCS at least 90 days before terminating a
high-volume service provider's contract without cause and prohibits termination
unless AHCCS determines network adequacy standards will continue to be met. Establishes
requirements relating to network adequacy studies and AHCCCS review.

Background

Managed care is
a health care delivery system used by states to administer Medicaid programs in
a manner that controls costs, manages utilization and ensures quality of care.
Under a managed care model, states enter into contracts with private and
non-profit MCOs who accept a set per member, per month payment for covered and
establish provider networks to meet member needs. States may draw down federal
funding for a managed care model, but must be able to continually demonstrate
adequate access to care and compliance with all other federal rules and
statutory requirements (
AHCCCS
;

Medicaid
).

AHCCCS
administers Arizona's Medicaid program and delivers covered services primarily
through contracts with health plans and other providers. The Director of AHCCCS
may enter into contracts necessary to administer the program, including prepaid
capitated arrangements for the provision of covered services to enrolled
populations (A.R.S. ��
36-2906

and
36-2907
).

An
RBHA

is an organization under contract with AHCCCS to coordinate the delivery of
mental health services in a geographically specific service area of Arizona for
eligible persons. A
service provider
is an organization or mental health
professional that meets the criteria established by AHCCCS and has a contract
with AHCCCS or an RBHA (
A.R.S.
� 36-3401
).

The Joint
Legislative Budget Committee states that the fiscal impact of S.B. 1629 cannot
be determined without receiving additional information from AHCCCS, but notes
that the bill may impact provider reimbursement or service utilization (
JLBC
fiscal note
).
