Module 2: Hospitalized Patient Review
This module focuses on the Physician Advisor’s core clinical responsibility: evaluating the hospitalized patient for appropriate status determination. It provides a structured approach to inpatient versus outpatient (observation) decision-making, grounded in medical necessity, regulatory guidance, and real-world hospital workflows.
Emphasis is placed on concurrent review, documentation assessment, risk stratification, and defensible clinical reasoning to support accurate status decisions and reduce downstream denials.

Lesson 1: IP vs. OBS - The Difference
This lesson explains the clinical, regulatory, and operational differences between inpatient (IP) and observation (OBS) services. It focuses on admission decision-making, documentation requirements, and review considerations, and includes practical documentation tips to support utilization review and physician education.
Rules That Shape The Decision
Lesson 2: IP vs. OBS - The 2 Midnight (MN) Rule
This lesson explains how the Two-Midnight Rule is applied in real-world Physician Advisor review. It addresses cumulative hospital time, physician expectation, medical necessity, and documentation requirements, and clarifies how the rule is used during concurrent review, post-discharge review, and physician education.
Lesson 2A: Dealing With The 2 Midnight (MN) Rule
This lesson addresses the CMS Two-Midnight Rule as it applies to Traditional Medicare (Fee-For-Service).
Although Medicare Advantage (MA) plans must comply with Medicare coverage standards, their utilization management processes, authorization requirements, and appeal pathways are contract-driven and may differ operationally. MA-specific processes are outside the scope of this document.

Lesson 3: Understanding the Inpatient Only List (IPO)
This lesson explains how the Inpatient-Only (IPO) List is used in Physician Advisor review and status determination. It addresses when the IPO List supports inpatient admission, when additional clinical judgment is required, and how changes to the IPO List affect procedural recommendations, documentation, and physician education.
Clinical Decision Support Tool
This reference tool supports inpatient recommendations following procedures in the context of the IPO List phase-out. It provides structured considerations for clinical risk, intensity of service, expected hospital course, and documentation elements necessary to support defensible inpatient determinations.
Lesson 4: InterQual & MCG - What Physician Advisors Need to Know
This lesson reviews the role of InterQual (IQ) and MCG criteria in utilization review and payer decision-making. It emphasizes appropriate use of criteria as a decision-support input — not a replacement for physician judgment — and provides practical guidance for documentation review and appeals.
