Sizing Bundled-Payment Opportunity Across 3,000 Hospitals from a 5% Claims Sample
Challenge
The company needed to identify and win hospital partners by sizing each hospital’s financial opportunity across five surgical episode categories, then convert that analysis into a self-serve sales engine its own team could run. The inputs made this hard: Medicare LDS claims provide only a 5% Part B sample, CMS does not publish hospital-specific target prices, and the payment-standardization rules are intricate. The sizing had to be defensible enough to put in front of a hospital CFO and consistent enough to rank thousands of facilities on the same basis.
Approach
We built a multi-stage, deterministic analytics pipeline over roughly 7 million Medicare episodes in DuckDB, moving from raw claims to a ranked opportunity per hospital. AI was confined to build time (reading CMS methodology documents, payment-standardization specifications, and program rules, and turning them into precise, testable specifications). The decisions themselves run as deterministic, versioned code: standardization arithmetic, RVU lookups, percentile benchmarks, and the opportunity score are tables and rules, not model judgment, so any number can be traced back to its inputs.
- Implemented CMS bilateral payment standardization to the published ResDAC v.14 methodology, so episode dollars are comparable across geographies.
- Estimated Part B spend from the 5% sample using RVU-based scaling rather than treating the partial sample as complete, and labeled those figures as estimates.
- Benchmarked target prices against peer-cohort percentiles, giving each hospital a defensible reference point in the absence of published CMS targets.
- Scored opportunity through an internal care-pathway cost model layered on the standardized episode economics.
- Validated the approach against external anchors: ACO double-dip attribution was checked against CMS MSSP public-use files.
- Extended the same deterministic foundation from the 30-day TEAMs window to a 90-day CJR-X window, including two-sided risk caps, without rebuilding the core.
Impact
- Phase 1 opportunity-ranking shipped and was signed off by the client.
- Produced a rank-ordered list covering about 3,000 hospitals, of which roughly 335 fall under the mandatory program, giving the sales team a prioritized target set.
- Delivered a production cloud analytics platform running in the client’s own AWS account (load balancer to Fargate to Aurora Serverless, with CI/CD), so the client owns and operates the asset.
- Built a JSON-driven, self-serve prospect-deck generator so the client’s team can produce hospital-specific pitch decks without engineering involvement.
- Extended the data foundation to a second bundled-payment program and to ACO overlap, sizing tens of millions in annual post-acute-care opportunity per flagship system. These opportunity figures are modeled from claims-derived episode economics and peer benchmarks, not realized savings.
Capabilities demonstrated
- CMS claims engineering at scale: episode construction and bilateral payment standardization (ResDAC v.14) over roughly 7M Medicare episodes.
- Sound statistical handling of partial data, including RVU-based Part B estimation from a 5% sample with estimates labeled as such.
- Peer-cohort percentile benchmarking to stand in for unpublished CMS target prices.
- Deterministic, auditable decision logic: standardization, scoring, and risk caps run as versioned code and tables, with AI limited to extraction and specification.
- Client-owned production delivery on AWS (Fargate, Aurora Serverless, CI/CD) plus a self-serve, JSON-driven deck generator.
