Coverage Summary

coverage_stance: covered_with_criteria. This policy (Policy Number: CS182ID.A, Effective Date: June 1, 2025, Last Review: June 1, 2025) applies to elective inpatient admissions for UnitedHealthcare Community Plan members in Idaho (including Idaho Medicaid Plus). It references InterQual criteria as a source to support medical necessity and level-of-care decisions and defines clinical, procedural, and operational factors that justify planned inpatient stays for non-obstetric surgical procedures.

Thresholds / Key Values

MELD Score> 8

GFR≤ 30 mL/min

Stroke/TIA timingwithin last 3 months

Age (increased anesthetic risk)≥ 85 years

Apnea Hypopnea Index (AHI)Moderate 15-30; Severe > 30

Acute Kidney Injury (AKI) definitionIncrease in serum creatinine ≥ 0.3 mg/dL in 48 hrs; or ≥1.5× baseline within 7 days; or >50% reduction in eGFR; or urine volume <0.5 mL/kg/hr for 6 hrs

Hemodynamic InstabilitySBP <90 mm Hg or decrease >40 mm Hg; oliguria <0.5 mL/kg/hr; MAP <65 mm Hg; capillary refill >3 sec; altered LOC; shortness of breath; persistent tachycardia

Medical Necessity Criteria

Medically Necessary Elective Inpatient Admission

A planned elective inpatient admission for certain surgeries or procedures is considered medically necessary when any of the following criteria are met:

Medical conditions increasing the risk of major post-operative complications

Advanced liver disease (MELD Score > 8)MELD Score > 8
MELD threshold specified
Cognitive status that warrants inpatient stay
Severe renal disease (GFR ≤ 30 mL/min)GFR ≤ 30 mL/min
Severe valvular heart disease
Stroke or TIA within last 3 monthswithin last 3 months
Symptomatic chronic lung disease (e.g., asthma, COPD)
Symptomatic coronary artery disease or heart failure
Unstable medical condition (e.g., poorly controlled diabetes)

Procedure-related factors that may increase the risk of complications

Anesthetic risk
- American Society of Anesthesiologists class III or greaterASA III or greater
  ASA III+ as anesthetic risk
- Age 85 years or olderage ≥ 85 years
- High risk for thromboembolism
- Moderate (AHI 15-30) to severe (AHI > 30) sleep apneaAHI 15-30 or AHI > 30

Need for pre- or post-operative services or monitoring

The need for pre-operative diagnostic studies that cannot be performed as an outpatient
Advance surgical planning determines inpatient recovery and care is required due to residence distance or lack of appropriate temporary residence
individual's residence distant to medical facility and no other appropriate nearby temporary residence available
Pre- or post-operative inpatient monitoring or treatment related to need to discontinue drugs or other therapies

Procedural-related events that may require inpatient stay

Acute Kidney Injury
See Definitions for AKI criteria
Altered mental status that is severe or persistent
Ambulatory or appropriate activity level status is not achieved
Conversion to open or complex procedure that requires inpatient care
Excessive drainage or bleeding from the operative site
Hemodynamic Instability
See Definitions for hemodynamic instability criteria

Provider Actions & Prior Authorization

Documentation Required

Document clinical criteria supporting inpatient admission

Provider must document one or more listed medical conditions, procedure-related risk factors, need for pre/post-operative monitoring, or procedural events that justify elective inpatient admission per policy.

Medical conditions (e.g., MELD > 8, GFR ≤ 30 mL/min, recent stroke/TIA within 3 months)
Anesthetic risk (e.g., ASA Class III+, age ≥ 85, moderate–severe OSA)
Procedure complexity (e.g., extensive dissection, complex wound/drain management)
Need for pre- or post-operative inpatient monitoring or treatment
Procedural-related events (e.g., AKI, hemodynamic instability, conversion to open procedure)

Prior Authorization

InterQual used for medical necessity determinations

UnitedHealthcare uses InterQual criteria as a source to support medical necessity and level of care decisions; providers should expect InterQual to be referenced during review.

Providers should expect InterQual to be referenced during review of medical necessity and level of care determinations.

Background & Evidence Sources

This policy applies only in the state of Idaho (including Idaho Medicaid Plus) and uses InterQual criteria to inform medical necessity and level-of-care determinations while relying on the independent clinical judgment of treating providers. Referenced specialty guidelines include the AASM (sleep medicine), AHA/ACC (perioperative cardiovascular evaluation), ASA (anesthesia/ASA Physical Status guidance), and GINA (asthma management). These sources are intended to guide decisions about the appropriate level of care (e.g., inpatient versus outpatient/observation) for elective surgical procedures.

Definitions

Acute Kidney Injury (KDIGO 2012): Increase in serum creatinine ≥ 0.3 mg/dL in 48 hours; or ≥1.5× baseline within 7 days; or >50% reduction in eGFR from baseline; or urine volume <0.5 mL/kg/hour for 6 hours.

Apnea Hypopnea Index (AHI): Number of apneas plus hypopneas per hour of sleep (events per hour) (AASM Scoring Manual).

Hemodynamic Instability: Vital sign abnormality not readily corrected by appropriate treatment, including one or more of: systolic blood pressure <90 mm Hg or decrease >40 mm Hg; oliguria (<0.5 mL/kg/hr); MAP <65 mm Hg; capillary refill >3 seconds; altered level of consciousness; shortness of breath; or persistent tachycardia.

ASA Physical Status Classification System: Subjective categorization of pre-anesthesia comorbidities (ASA I–VI) used to assess operative risk.
