Multiple A/B MACs with Different Policies
90.4.2 – Multiple A/B MACs with Different Policies
(Rev. 120, Issued: 01-16-15, Effective: 01-01-15, Implementation: 01-01-15)
When there are multiple A/B MACs that have different coverage policies in an MA
plan’s service area, the MA plan must choose from the following alternatives for its
coverage policy. Note: All DME MACs have the same LCDs; therefore, there should not
be differences related to DME coverage in a plan’s service area.
Local Plans:
1. A local MA plan may choose to adopt the coverage policy that applies to original
Medicare beneficiaries. In this alternative, the coverage policy that applies to plan
enrollees will be that of the A/B MAC with jurisdiction over the state in which the
service is furnished to the enrollee.
2. A local MA plan that chooses to adopt a uniform coverage policy that will apply
uniformly to all plan enrollees, may choose the A/B MAC coverage policy
applicable in its service area that is the most beneficial to enrollees.
• The MA plan must make information on the selected coverage policy
determinations readily available, including through the plan’s website, to all
enrollees and health care providers; and
• The MAO must notify CMS, through its account manager, 60 days before the
date bids are due, if it elects to adopt a uniform local coverage policy for any
plan or plans in the subsequent year (42 CFR § 422.101(b)(3)(i)). In preparing
this notification, the MAO should include, at a minimum:
o An identification of the plan(s) and service area(s) to which the uniform
local coverage policy or policies will apply;
o The competing local coverage policies involved; and
o A table contrasting the local coverage areas by listing and comparing
those policies in each coverage area that represent expansions of Medicare
Part A and Part B services.
CMS will review notices provided to evaluate the selected policy or policies on
the bases of cost, access, geographic distribution and health status of enrollees.
CMS will notify the MAO of its approval or denial of the selected uniform local
coverage policy or policies.
Regional Plans:
1. A regional MA plan may choose to adopt the coverage policy that applies to
original Medicare beneficiaries. In this alternative, the coverage policy that
applies to plan enrollees will be that of the A/B MAC with jurisdiction over the
state in which the service is furnished to the enrollee or
2. A regional MA plan that chooses to adopt a uniform coverage policy must select
one of the A/B MACs with jurisdiction in the plan service area and apply the
policies of that A/B MAC uniformly to all enrollees of the plan.
• Plans must make information on the selected local coverage policy
determinations readily available, including through the plan’s website, to all
enrollees and health care providers.
• Regional MA plans may not select local coverage policies from more than one
A/B MAC and selection of the coverage policy is not subject to CMS pre-
approval (42 CFR § 422.101(b)(4)) but must notify CMS, through their
account managers, 60 days before the date bids are due, if the plan elects to
adopt a uniform local coverage policy for any plan or plans in the subsequent
year (42 CFR § 422.101(b)(3)(i)). In preparing this notification, plans should
include, at a minimum:
o An identification of the plan(s) and service area(s) to which the uniform
local coverage policy or policies will apply;
o The competing local coverage policies involved; and
o A table contrasting the local coverage areas by listing and comparing
those policies in each coverage area that represent expansions of Medicare
Part A and Part B services.
Note: If a local or regional MA plan adopts a uniform coverage policy as indicated above,
that uniform coverage policy only applies to its service area. Services for an enrollee
from a provider outside the service area are covered based on the local coverage
determinations of that provider’s geographic location.
