both in- and out-of-network cost-sharing for all Part A and Part B services. The MOOP
dollar limits are set annually by CMS and include all cost-sharing (i.e., deductibles,
coinsurance, and co-payments) for Part A and Part B services, although an MA plan may
also include supplemental benefits as services subject to the MOOP. CMS also may
annually establish a lower, voluntary MOOP limit. Plans that adopt the lower voluntary
MOOP limit will have more flexibility in establishing cost-sharing amounts for Part A
and Part B services than those that do not elect the voluntary MOOP. MAOs must track
enrollee out-of-pocket costs and should notify enrollees when they reach, or are near, the
plan’s MOOP limit.
For any dual eligible enrollee, MA plans must count toward the MOOP limit only those
amounts the individual enrollee is responsible for paying, net of any state responsibility
or exemption from cost-sharing, and not the cost-sharing amounts for services the plan
has established in its plan benefit package. Effectively, this means that, for dual eligible
enrollees who are not responsible for paying the Medicare Part A and Part B cost-sharing,
the MOOP limit will rarely, if ever, be reached. However, plans must still track out-of-
pocket spending for these enrollees.
During a contract year, when an enrollee switches to another plan of the same type (for
example, from one HMO to another HMO) offered by the plan, his/her accumulated
annual contribution toward the annual MOOP limit in the previous plan to date is to be
counted towards his/her MOOP limit in the new MA plan. As applicable, this transfer of
MOOP applies to both in-network and out-of-network MOOP.
Additionally, MA plans may extend the transferability of the enrollee’s contribution
toward his/her annual MOOP so that it applies to an enrollee’s transfer during the
contract year to any MA plan type offered by the MAO. For example, if an enrollee
makes a mid-year change to move from an HMO to a PPO offered by the same MAO,
his/her current contribution toward the MOOP limit may follow the enrollee and be
counted towards the MOOP limit in the PPO. This allows those enrollees who are eligible
to make mid-year plan changes to freely select among the diverse MA plan options
offered by an MAO.
Per Member Per Month (PMPM) Actuarial Equivalent (AE) Cost-sharing Requirement:
The actuarially estimated total MA cost-sharing for Part A and Part B services must not
exceed cost-sharing for those services in original Medicare. In addition, CMS evaluates
particular service categories; inpatient facility, SNF, DME, and Part B drugs, for actuarial
equivalence. MA plans should refer to annually published guidance regarding the
application of this requirement.
Service Category Cost-sharing Standards: As provided under 42 CFR §422.100(f)(6),
MA plan cost-sharing for Part A and Part B services specified by CMS must not exceed
levels annually determined by CMS to be discriminatory. In addition, under section
1852(a)(1)(B)(iii) of the Act (as amended by the Affordable Care Act) the cost-sharing
charged by MA plans for chemotherapy administration services, dialysis services, and
