Description
Preadmission and preoperative services are often necessary to ensure the health and safety of a member before they undergo surgery or an inpatient admission. A wide range of examinations and diagnostics may be considered preadmission or preoperative services, including, but not limited to X-ray, laboratory tests, and EKGs.
Centers for Medicare and Medicaid Services (CMS) “Three-day window” rule considers these related preadmission and preoperative services incidental to the subsequent facilities admission or surgical payment.
CMS “Three‐day window” definition:
“Defined as three (3) days prior to and including the date the beneficiary is admitted as an inpatient. For example, if a beneficiary is admitted as an inpatient on Wednesday, then Sunday, Monday, Tuesday, or Wednesday is part of the three‐day window. Under the payment window policy, a hospital (or an entity that is wholly owned or wholly operated by the hospital) must include on the claim for a beneficiary's inpatient stay, the diagnoses, procedures, and charges for all outpatient diagnostic services and admission-related outpatient nondiagnostic services that are furnished to the beneficiary during the 3-day payment window.” (Medicare Claims Processing Manual, Pub. 100-04, Chapter 12, Section 90.7 and 90.7.1)
Diagnostic services (including clinical diagnostic laboratory tests) provided to a beneficiary by the admitting hospital, or by an entity wholly owned or wholly operated by the admitting hospital (or by another entity under arrangements with the admitting hospital), within 3 days prior to and including the date of the beneficiary's admission are deemed to be inpatient services and included in the inpatient payment. (Medicare Claims Processing Manual, Pub. 100-04, Chapter 3, Section 40.3)
This policy applies to facility claims. Please refer to global allowance rules in the Bundling Guidelines policy for professional claims.
