Surgical scope and baseline cost
Build the case from sourced evidence and explicit owner requests. These are requested inputs, not measured NYU facts.
Start with the public evidence
Establish an inpatient discharge cohort and published payment exposure, then keep the remaining operating inputs explicit.
Read the cohort and post-acute analysis method
SPARCS discharge records: choose facility, year and APR cohort
TEAM participation: distinguish membership from episode eligibility
SNF, IRF and home-health payment tables: match year, geography and units
Need owner: NYU finance and case sponsor
Confirm surgical inclusion on cost-avoidance basis. Supply baseline costs, timing and avoidable fraction. Rates and charges cannot replace cost; deferred is not avoided. Status: need.
Find source records and their limits
Inspect published rates, not operating cost
