Definition:The month, day, and year of admission to acute inpatient care.
Suggested Data Collection Question:What is the date the patient was admitted to acute inpatient care?

Allowable Values:

MM = Month (01-12)
DD = Day (01-31)
YYYY = Year (20xx)

Notes for Abstraction:
  • The intent of this data element is to determine the date that the patient was actually admitted to acute inpatient care. Because this data element is critical in determining the population for all measures, the abstractor should NOT assume that the claim information for the admission date is correct. If the abstractor determines through chart review that the date is incorrect, for purposes of abstraction, she/he should correct and override the downloaded value. If using claim information, the ‘Statement Covers Period’ is not synonymous with the ‘Admission Date’ and should not be used to abstract this data element. These are two distinctly different identifiers:
    • The Admission Date (Form Locator 12) is purely the date the patient was admitted as an inpatient to the facility.
    • The Statement Covers Period (“From” and “Through” dates in Form Locator 6) identifies the span of service dates included in a particular claim. The “From” Date is the earliest date of service on the claim.
  • For patients who are admitted to Observation status and subsequently admitted to acute inpatient care, abstract the date that the determination was made to admit to acute inpatient care and the order was written. Do not abstract the date that the patient was admitted to Observation.
Example: Medical record documentation reflects that the patient was admitted to observation on 04-05-20xx. On 04-06-20xx the physician writes an order to admit to acute inpatient effective 04-05-20xx. The Admission Date would be abstracted as 04-06-20xx; the date the determination was made to admit to acute inpatient care and the order was written.
  • If there are multiple inpatient orders, use the order that most accurately reflects the date that the patient was admitted.
  • For newborns that are born within this hospital, the admission date is the date the baby was born.
  • The admission date should not be abstracted from the earliest admission order without regards to substantiating documentation. If documentation suggests that the earliest admission order does not reflect the date the patient was admitted to inpatient care, this date should not be used.
Example: Preoperative Orders are dated as 04-06-20xx with an order to admit to Inpatient. Postoperative Orders, dated 05-01-20xx, state to admit to acute inpatient. All other documentation supports that the patient presented to the hospital for surgery on 05-01-20xx. The admission date would be abstracted 05-01-20xx.
