CMS Pub. 100-16, ch. 4, § 60
Meaningful Difference
The guidance in this section applies to non-employer MA and MA-PD plans of all types.
CMS reserves the right to extend the guidance in this section to employer plans in future
years.
As provided under 42 CFR §422.254(a) (5) and §422.256(b)(4)(i), CMS annually reviews
bids to ensure that an MAO’s plans in a given service area are meaningfully different
from one another in terms of key benefits or plan characteristics. Although the specific
guidelines and criteria for meaningful difference may change, the criteria CMS may use
to make this determination include:
• Cost-sharing: CMS sets a minimum differential in enrollees’ expected out-of-pocket
spending between an MAO’s plans of the same type in a service area;
• Mandatory supplemental benefits offered;
• Plan type;
• Inclusion of a Part D benefit (i.e., MA plan is meaningfully different from an MA-PD); and
• Premiums.
CMS annually publishes guidelines to assist MAOs in creating plan designs in a given
area with meaningful differences. MAOs offering more than one plan in a given service
area should ensure that enrollees can easily identify the differences in benefit coverage
between the plans. Beneficiaries should be able, for example, to determine which plan
provides the highest value based on their needs. Plan bids that CMS determines are not
meaningfully different during the annual CMS review of submitted plan bids will not be
approved and MAOs will be required either to withdraw or consolidate such offerings.
Example: An MAO offers three plans in a service area with the characteristics listed
below. Since each plan differs from the other two plans by one of the characteristics
described above, this MAO is considered to be offering plans with meaningful
differences;
• Non SNP, MA-only;
• Non SNP, MA-PD; and
• SNP, MA-PD.
