Article Overview

This article summarizes proposed FY 2020 IPPS changes that affect hospital inpatient coding and grouping logic. It is aimed at coders, CDI professionals, DRG analysts, and reimbursement teams who need a high-level view of upcoming updates to MS-DRGs, ICD-10-CM, and ICD-10-PCS across several body systems and severity categories. The discussion spans diagnosis and procedure reassignments, DRG title and structure changes, OR/non-OR procedure status changes, and proposed CC/MCC designation revisions.

Why This Topic Matters

These proposed changes can affect inpatient DRG assignment, severity level reporting, and related reimbursement and quality-impacting classifications. Reviewing them helps organizations prepare for code set and grouper logic updates before they take effect.
