From HCC to CDPS: A Primer on Common Risk Adjustment Models
Dive into healthcare risk adjustment models: from HCC to Medicare, Medicaid, and ACA. Understand the science behind equitable healthcare financing.
Over the past decade, the Centers for Medicare & Medicaid Services (CMS) has developed more than 50 Alternative Payment Models (APMs) with the goal of incentivizing low-cost, high-quality care for Medicare FFS beneficiaries. In April 2019, CMS announced its latest model, the Direct Contracting Entity (DCE), which began its first performance year on April 1, 2021. With DCEs, CMS is making one of its largest bets on value-based care to date, expanding participation to a wider group of providers than ever before. To help CMS accomplish its goal, DCEs will need to maximize savings via targeted risk adjustment and patient engagement interventions — and this starts with beneficiary alignment.
Beneficiary Alignment Calculation
DCEs are similar to other APMs in that their savings and losses are tied to the difference between annual expenditures of aligned beneficiaries and a financial benchmark calculated for those beneficiaries. Additionally, CMS currently plans to base their risk adjustment factor (RAF)calculations solely off of fee-for-service (FFS) claims data and Medicare Advantage (MA) Risk Adjustment Processing System (RAPS) data, without taking into account a separate stream of Hierarchical Condition Categories (HCCs) from chart reviews. This makes prospective risk adjustment and patient engagement interventions critical for DCEs.
To inform these interventions, DCEs will need to anticipate who is aligned to their organization, how they are aligned, and if they are on track to align in the future. CMS calculates DCE benchmarks by multiplying the number of beneficiaries by its base rate and risk score.
For each component of this calculation, there are associated questions DCEs must be able to answer1:
CMS passively updates this calculation as claims flow in. Meanwhile, DCEs can take additional steps to maximize savings by actively engaging with and optimizing each of these components, starting with understanding which beneficiaries will be aligned to their organization.
Who Will Align to Your DCE & How
To determine which beneficiaries will be aligned, a DCE should “clean” its pool of potential beneficiaries according to CMS’s alignment eligibility criteria, which differs based on the model:
Standard & New Entrant Eligibility Criteria2:
Prospective Plus entering Q2, Q3, or Q4 Eligibility Criteria:
Once a DCE has determined which beneficiaries are eligible to align to its model, it must then consider how those beneficiaries may become aligned: through voluntary or claims-based alignment. For claims-based alignment, CMS will align an eligible beneficiary to a particular DCE based on where they receive the plurality of their Primary Care Qualified Evaluation & Management (PQEM) services, as evidenced in claims utilization data. For a given payment year (PY), this algorithm takes data from the 24-month period spanning 30 months before PY start, to six months before PY start. This 24-month period is referred to as “alignment years.”
Beneficiaries can also designate a DC Participant Provider as their main provider and become voluntarily aligned with that provider’s DCE the following PY. Under Prospective Plus alignment, this alignment comes into effect the following quarter. Voluntary alignment takes precedence over claims alignment. However, a beneficiary can be removed from voluntary-alignment if, in a PY, none of the DCE’s Participant or Preferred Providers furnish services to the beneficiary and an outside provider submits a PQEM claim. While voluntary alignment comes down to a one-time human decision, claims-based alignment is based on an algorithm. This algorithm is straightforward and lends itself to DCEs looking to track where their alignment is headed.
So, why does it matter how a beneficiary is aligned? Because the beneficiary base rate is based on whether they are claims aligned or voluntary aligned — and this can impact risk adjustment.
If a beneficiary meets the criteria described above, they can become both voluntary and claims aligned to the same DCE. For example, a beneficiary who starts out with purely voluntary alignment to a DCE will also become claims aligned once the plurality of their PQEM services in the alignment years are furnished by the DCE.
How DCEs conceive of this “both-aligned” beneficiary depends on the context of the question. For benchmarking purposes, this both-aligned beneficiary is treated as claims aligned. For questions about which organization they will align to in the future, their voluntary alignment status takes precedence over any updates to their claims-based alignment status.
How Beneficiary Base Rate is Determined
The way beneficiary base rate is defined differs based on whether they are claims aligned or voluntary aligned. For claims-based alignment, the base expenditure for beneficiaries for PY2 takes a blend of the PY regional rate (35%) and the 2017, 2018, and 2019 expenditures for beneficiaries who would have been aligned in those years, trended forward using the United States Per Capita Cost (65%).
The DCE Regional Rate Baseline Adjustment converts the regional rate into this blended rate. For voluntary-alignment, the baseline is 100% based on the regional rate from the DC/KCC rate book, for the counties in which beneficiaries reside in PY22. In PY5, voluntary-aligned beneficiaries’ 2021, 2022, and 2023 expenditures are blended with the 2021, 2022, and 2023 regional rates to arrive at the benchmark. In PY6, the years 2022, 2023, and 2024 are used.
As mentioned above, the way a beneficiary is aligned impacts a DCE’s risk adjustment. For claims-aligned beneficiaries, the PY 2/2022 risk score is capped at 103% of the 2020 reference year risk score (based on 2019 DOS).3 As an example, one might have a reference year risk score of 1.162. If the PY raw risk score is 1.200, it will need to be reduced down to 1.194 so as not to exceed 103% of the 1.162 reference year risk score.
For voluntary-aligned beneficiaries, the PY2 score is not capped at 103% of the 2020 reference year risk score, nor is it subjected to the Coding Intensity Factor. In this example, the PY2 raw risk score for voluntary-aligned beneficiaries is 1.24. Though this exceeds 103% of 1.159, this score is not capped. This exemption means that a DCE has more freedom to adjust risk scores for voluntary-aligned beneficiaries.
Analytical Approaches to Alignment
Returning to the first question — who is aligned to my DCE — it is worth noting that CMS will tell DCEs in the form of de-identified alignment data as well as beneficiary-identifiable reports.
These reports include:
CMS commits to providing information about a DCE’s beneficiaries for a given PY in advance of that PY, but these reports are largely after-the-fact in scope and answer the question “Who has been aligned to me?” In order to execute impactful prospective interventions, a DCE needs to ask this question well before it is finalized: “Who is on track to become aligned to me, or to align away from me?” A DCE can extrapolate these counts going into 2022 by sorting their beneficiaries according to the rules of the claims-based alignment algorithm.
Case Study: Claims-Based Alignment Projection for 2022 & 2023
The table below considers beneficiaries currently aligned to a DCE, and beneficiaries not-yet-aligned who may become claims-aligned to a DCE. The negative numbers in parentheses represent those beneficiaries who are not aligned to the DCE for the years in question (2021 vs. 2022 expectation). Beneficiaries who are “both-aligned” are made a subcategory of “voluntarily aligned” in the first table, but are subsumed within the claims-aligned in the bottom table for the purpose of benchmark calculation.
With these estimates, a DCE may choose the following set of interventions for the distinct cohorts highlighted:
Any of these interventions can be further optimized by overlaying the level of need and cost for a given provider’s patients and prioritizing accordingly. A holistic estimate of enrollment for the coming year will allow a DCE to check whether it risks falling below the minimum aligned beneficiary count. A DCE may employ a combination of the interventions above to ensure this doesn’t happen.
Impacting the Benchmark
Since the benchmark is sized according to a DCE’s risk scores, informed prospective risk adjustment interventions such as those described above will help ensure an accurate benchmark and increase a DCE’s chances of enjoying savings.
A DCE should target 6% RAF growth over the Reference Year for claims-aligned beneficiaries to ensure it hits the 3% cap on risk score growth. High-risk beneficiaries who are voluntary aligned (and thus exempt from the cap) should also be prioritized for risk adjustment. On the expenditure side, the same mapping can inform patient engagement and utilization management, enabling a DCE to increase its savings in whichever benchmark it’s working with.
DCE Toolkit for Beneficiary Alignment & Risk Adjustment
Once a DCE understands the key principles of beneficiary alignment, they will need to develop a toolkit to put that information to use. The following capabilities are key for any DCE looking to intervene systematically with its benchmark and expenditures:
While the DCE model may add a layer of complexity to an organization’s financial operating plan, it represents an unprecedented opportunity for smaller provider groups to enter into the world of value-based care. DCEs that are able to strategically leverage the model’s alignment algorithm and benchmark calculation will have a far greater likelihood of success than those that are reactive. Working with a strong risk adjustment analytics partner will be key to helping them break through the uncertainty, maximize savings, and ultimately help accomplish CMS’s goal of delivering low-cost, high-quality care.
