Dedicated Precursors

• [SO/URSA-CORE] Ambulatory Surgical Center Encounter Document Aggregator, Precursor 2 (Qualifying Documents): One record per professional claim or bill service line item, institutional claim or bill service line item, or EMR encounter record providing qualifying evidence that an ambulatory surgical center (ASC) encounter took place; current logic assumes that a single professional bill or claim will contain services for at most a single ASC encounter. NB: rarely, these encounters last more than 1 day; however, the claim covered start and end dates for institutional claims / bills are not reliable for establishing the encounter start and end dates, because the covered periods sometimes includes pre-op testing and other services; so we impute the actual date of surgery from institutional claim service line items with OR setting services, and assume the day of surgery was the first day of the encounter. We also find that professional claims / bills for multi-day encounters seem to overwhelmingly have claim covered start dates on the encounter start date, so we do not attempt to match professional services starting after the encounter start date -- it's not worth the additional computational burden to catch the handful (if any) of these instances.
• [SO/URSA-CORE] Ambulatory Surgical Center Encounter Document Aggregator, Precursor 1 (Disqualifying Patient Days): One record per patient-date in which an institutional or professional claim or bill, or EMR encounter record exists meeting all of the following criteria: (1) evidence of surgery; (2) no evidence that surgery was performed at an ASC; and (3) is not a part of an inpatient admission or ED parent encounter. This object will be used to disqualify otherwise qualifying professional claims or bills falling on the same date, under the theory that the professional service place of service was misdocumented (i.e., documented as ASC, but should be, e.g., hospital outpatient).
