Parametric insurance: A captivating solution
Parametric policies, which pay based on the magnitude of an event, can bridge coverage gaps that are difficult to insure with a traditional indemnity policy.
Using the Milliman MACVAT®, a tool providing a comprehensive benefit summary of individual MA plans, we analyzed all 2022 individual MA plans to determine the breadth of combo offerings available to beneficiaries, drilling down to the service category in each plan benefit package (PBP). We specifically focused on each of the benefits contained in the combo benefit, as there are multiple ways an MA organization can combine specific PBP categories into a combo benefit.
The combo benefit allows plans to combine supplemental benefits into groups with a maximum plan benefit amount. One popular example is offering a combined maximum benefit limit for both preventive and comprehensive dental. Another example is a plan offering a combined visit limit across chiropractic and acupuncture services. The maximum plan benefit amount can be a total dollar limit, a total visit limit, or varying maximums by benefit included in the package. Plans are required to designate whether the enrollee must select from one or more of the benefits (as opposed to having access to all of the benefits in the package). In 2022, MA rules allow plans to cover up to three packages of combo benefits.
Key takeaways from this analysis include:
Plans are able to include any allowable supplemental benefit in their combo benefit. Figure 1 shows the percentage of beneficiaries by varying plan/carrier characteristics with combo benefit coverage in 2022.1
About 77% of beneficiaries enrolled in preferred provider organizations (PPOs)—including local PPOs (LPPOs), regional PPOs (RPPOs), and health maintenance organizations with added point-of-service benefits (HMO-POS plans)—are covered by combo benefits, while 63% of beneficiaries in HMOs have combo benefit coverage. Beneficiaries enrolled in D-SNPs are the most likely to be covered by combo benefits (about 79% coverage) relative to beneficiaries in general enrollment plans and chronic condition special needs plans (C-SNPs), about 64% coverage). General enrollment plans with zero-dollar premiums offer combo benefits to a higher percentage of beneficiaries than plans with non-zero premiums; the same holds true for national versus regional organizations.
Combined dental limits are the most commonly offered combo benefit package, covering about 58% of total MA enrollment. Some MA plans have offered combined limits across preventive and comprehensive dental services for many years. Starting in 2022, the Centers for Medicare and Medicaid Services (CMS) requires plans offering this benefit structure to identify combined preventive and comprehensive dental limits formally as combo benefits in the PBP. While rarely done in 2022, it is possible to include other benefits alongside dental within the same package; about 0.4% of beneficiaries are covered by a combo benefit that includes dental along with other services within the same package. Figure 2 shows the percentage of beneficiaries by plan characteristic with combo benefit coverage including dental in 2022.
A comparison of Figures 1 and 2 shows that, in total, about 85% of beneficiaries with combo benefits receive dental coverage under a combo benefit. Dental combo benefits are the least common in regional organizations, where 29% of beneficiaries have a combo dental benefit while 52% of regional beneficiaries have any type of combo benefit; this is in part because regional organizations tend to offer separate preventive and comprehensive dental limits more frequently than national organizations. Additionally, PPOs are the most likely to include dental in a combo benefit, as only about 5% of beneficiaries in PPOs have a combo benefit that does not include dental (77% of beneficiaries have access to a combo benefit while 72% have access to a combo benefit including dental).
For plans with a dental combo benefit, the maximum benefit value varies widely. Figure 3 shows the enrollment-weighted average dental combo limit by plan characteristic, rounded to the nearest $100.
The average dental combo benefit for HMO plan types is larger than those offered under HMO-POS and PPO plan types, at about $1,900 annually versus about $1,400 and $1,500 annually, respectively. The average D-SNP dental combo benefit limit is about twice that of the average general enrollment plan’s combo dental benefit limit (about $2,900 annually versus about $1,400 annually).

The interactive graphic in Figure 4 demonstrates the percentage of beneficiaries with coverage within a combo benefit package for each high-level PBP service category. This graphic allows the user to include or exclude dental coverage from the interactive graphic, which is generally significantly more prevalent than other benefit offerings. The categories are ranked by the percentage of membership covered for each category across the total market. Aside from dental, demonstration programs are offered most frequently in combo benefits, with about 12% of membership covered. This includes Value-Based Insurance Design (VBID), Uniformity Flexibility (UF), and Special Supplemental Benefits for the Chronically Ill (SSBCI), which are all offered non-uniformly to beneficiaries based on individual eligibility. Demonstration programs are closely followed by OTC benefits, with about 10% of membership covered. Other benefits with more than 5% of membership covered across the entire market are fitness, home and bathroom safety devices and modifications, health education, worldwide emergency coverage, and acupuncture.
We reviewed the data categorized by SNP type. We note very few I-SNPs offer non-dental combo benefits, and so they are not included in this graphic.
While not summarized directly in the interactive graphic, D-SNPs are by far the most prevalent enrollment type offering non-dental combo benefits, with about 54% of enrollment in D-SNP plans with access to a non-dental combo benefit. This is relative to about 11% of general enrollment plans and about 18% of C-SNP plans.
We summarized combo benefit coverage data by broad plan type: HMO, HMO-POS, and PPO, including both local PPOs (LPPOs) and regional PPOs (RPPOs). Private fee-for-service (PFFS) plans are excluded due to the limited enrollment in this plan type and subsequent limited offering of combo benefits.
We summarized combo benefit coverage data by national and regional organizations. We classified the following organizations as national: Anthem, Centene/WellCare, CIGNA, CVS Health/Aetna, Humana, Kaiser, and UnitedHealth, with the remainder of plans being identified as regional.
While not summarized directly in the interactive graphic, regional organizations are about two times more likely to offer a non-dental combo benefit than national plans. About 29% of beneficiaries enrolled in regional organizations are covered by a non-dental combo benefit, while about 15% of beneficiaries enrolled in national organizations are covered by a non-dental combo benefit.
Finally, we summarized combo benefit coverage data by 2022 beneficiary premiums (Part C plus Part D premiums), distinguishing between general enrollment plans that have zero-dollar premiums and non-zero-dollar premiums. General enrollment plans tend to focus on zero-dollar premium plan offerings more than other plan types; D-SNPs, for example, generally target a premium equal to the low-income benchmark (LIB).
The majority of beneficiaries are enrolled in a plan design that includes a combo benefit, and the majority of these plans include combined preventive and comprehensive dental limits. However, the nearly 15% growth in non-dental combo benefits across the market from 2021 to 2022, and the high prevalence of D-SNP plans offering non-dental combo benefits, suggest plans are thinking strategically about how combo benefits support plan competitiveness and enrollment growth.
To perform these analyses, we relied on detailed information on MA plan combo benefit offerings for 2022. We also used publicly available MA enrollment information from January 2022 to develop enrollment-weighted averages by the groupings noted above. The various groupings we analyzed include:
The values presented reflect plans available in 2022. The information released by CMS includes detailed cost-sharing information by PBP service category, enrollee premium, and enrollment by plan. We used the 2022 Milliman MACVAT® (which summarizes the previously mentioned information released by CMS).
We included all individual plans, e.g., non-employer group waiver plan (non-EGWP) MA prescription drug (MAPD) plans. We excluded standalone prescription drug plans (PDPs), medical savings account (MSA) plans, Medicare-Medicaid plans (MMPs), Program for All-Inclusive Care of the Elderly (PACE) plans, Part B-only plans, and Cost plans.
