Coverage Summary

Background: UnitedHealthcare applies InterQual criteria to assist with medical necessity and level-of-care determinations. This policy (Policy Number MP.19.10) applies to UnitedHealthcare Commercial and Individual Exchange plans and may be applied to Medicare Advantage when no Medicare National Coverage Determination (NCD) or Local Coverage Determination (LCD) exists. The policy does not apply to an obstetric member during pregnancy, childbirth, or the post-partum period.

Scope summary: Defines clinical criteria under which planned elective inpatient admissions for surgeries or procedures are considered medically necessary for UnitedHealthcare Commercial and Individual Exchange plans; excludes obstetric care during pregnancy/childbirth/postpartum. Uses InterQual as an evidence/operational criteria source and references multiple specialty guidelines. Coverage stance: covered_with_criteria. Policy Number: MP.19.10. Status: CURRENT. Effective/Last review date: January 1, 2026.

Provider Actions & Prior Authorization

Documentation Required

Document clinical justification for inpatient admission

Providers must document which specific medical condition(s), procedure-related factors, complexity elements, advance planning reasons, or procedure-related events from the policy are present to justify a planned elective inpatient admission.

Medical conditions increasing postoperative risk (e.g., MELD Score > 8, GFR ≤ 30 mL/min, recent stroke/TIA, symptomatic coronary artery disease or heart failure)
Procedure-related risk factors (e.g., ASA class III or greater, age ≥ 85, moderate–severe OSA with AHI ≥15, persistent electrolyte abnormalities, risk of postoperative airway compromise)
Complex procedure or post‑operative care needs (e.g., unusually extensive dissection, complex drain management, prolonged surgery, need for preoperative diagnostics not available outpatient)
Advance planning reasons (e.g., distant residence with potential for urgent complications, need to discontinue therapies requiring inpatient monitoring)
Procedure-related events (e.g., acute kidney injury per KDIGO criteria, hemodynamic instability, conversion to open/complex procedure, excessive bleeding, altered mental status)

Prior Authorization

Potential use of InterQual to support level-of-care decisions

UnitedHealthcare uses InterQual criteria as a source to support medical necessity and level-of-care decisions; providers should expect payor review using InterQual where applicable and supply supporting documentation.

InterQual may be used by the payor to review level-of-care decisions; supply documentation that maps the patient’s condition, procedure factors, or events to the policy/InterQual rationale.

Definitions & Evidence

UnitedHealthcare uses InterQual criteria as a source of medical evidence to support medical necessity and level-of-care decisions, when applicable, in connection with professional clinical judgment. This policy applies to UnitedHealthcare Commercial and Individual Exchange plans and may be applied to Medicare Advantage in the absence of an NCD/LCD. Note: the policy excludes obstetric members during pregnancy, childbirth, and the post-partum period.

Definitions

Acute Kidney Injury: Defined as any of: increase in serum creatinine ≥ 0.3 mg/dL in 48 hours; increase in serum creatinine ≥ 1.5 times baseline within prior 7 days; reduction >50% in estimated GFR from baseline; urine volume < 0.5 mL/kg/hour for 6 hours (KDIGO, 2012).creatinine ≥ 0.3 mg/dL in 48 hours; ≥1.5x baseline in 7 days; urine <0.5 mL/kg/hr for 6 hrs

KDIGO 2012

Apnea Hypopnea Index (AHI): Number of apneas plus hypopneas per hour of sleep (events/hour). Severity: moderate AHI 15-30 events/hour; severe AHI > 30 events/hour.AHI 15-30 (moderate); AHI > 30 (severe)

AASM 2008

Hemodynamic Instability: Vital sign abnormality not readily corrected by appropriate treatment, indicated by one or more: systolic BP <90 mm Hg or decrease >40 mm Hg; oliguria goal 0.5 mL/kg/hr; MAP <65 mm Hg; new abnormal capillary refill >3 sec; altered LOC; shortness of breath; persistent tachycardia.systolic BP <90 mm Hg or decrease >40 mm Hg; MAP <65 mm Hg; urine output 0.5 mL/kg/hr

ASA Physical Status Classification: Six-class system assessing pre-anesthesia medical comorbidities; ASA III or greater cited as anesthetic risk factor.ASA III or greater

ASA 2020

Evidence and guideline sources: guideline references include the 2024 AHA/ACC perioperative cardiovascular guideline, ASA statements (2014 practice guideline on OSA management and 2020 ASA statement on the ASA Physical Status Classification System), the AASM definitions and OSA severity classifications, KDIGO 2012 criteria for Acute Kidney Injury, and the 2023 GINA report for asthma. UnitedHealthcare also uses InterQual criteria as the operational source to support medical necessity and level-of-care decisions.
