Article Overview
This article reviews diabetes mellitus from a coding, documentation, and risk-adjustment perspective. It covers CMS-HCC v28 and related HHS-HCC and Elixhauser categories, broad diabetes classification concepts, diagnostic criteria, common acute and chronic complications, and CDI/provider documentation considerations for accurate reporting. It is intended for coders, CDI specialists, auditors, and clinicians who document or review diabetes diagnoses and complications.
Why This Topic Matters
Diabetes coding affects risk adjustment, quality measurement, and problem-list accuracy. The article helps readers understand how diabetes type, complications, and related documentation patterns influence classification and downstream reporting.
