Presentation Slides

Pdf Summary

The document provides an overview of the ICD-10-CM updates for Fiscal Year 2026, issued by the CDC in June 2025, with 487 additions, 28 deletions, and 38 revisions, totaling 74,719 codes. Key updates include new guidelines, coding changes by chapter, and important coding tips, especially in cardiovascular (CV) diagnoses.<br /><br />Significant guideline changes involve documentation exceptions for certain clinical measurements (BMI, ulcer depths, stroke scales, etc.), coding for multiple anatomical sites, and clarification on diabetes remission coding. COVID-19 coding guidance is updated to only allow confirmed diagnoses (code U07.1), with instructions on asymptomatic positive cases and provider queries for clarity.<br /><br />Excludes 1 and Excludes 2 notes are clarified to denote mutually exclusive or coexisting conditions, respectively. Hypertension guidelines emphasize coding causal relationships with heart and kidney conditions, specifying categories I11, I12, and I13 for hypertensive heart disease, chronic kidney disease, and their combination. Controlled and uncontrolled hypertension, hypertensive crisis, and related coding are detailed.<br /><br />Cardiovascular conditions coding tips cover preoperative cardiovascular exams, valve disease specificity, acute myocardial infarction (AMI) types 1 and 2 distinctions, and the classification of myocardial infarctions types 3 to 5. The document also defines various arrhythmias, including bradycardia types, supraventricular tachycardia, atrial flutter/fibrillation subtypes, ventricular tachycardia variants, ventricular flutter/fibrillation, and congestive heart failure stages and types.<br /><br />Coding chapters reflect numerous updates, including new codes for neoplasms, infectious diseases, endocrine disorders (e.g., type 2 diabetes in remission), eye/ear diseases, circulatory system (e.g., Fontan-associated conditions), skin ulcers, genitourinary diseases, musculoskeletal conditions, congenital malformations, injuries, and social determinants of health in Chapter 21.<br /><br />The document emphasizes the importance of risk adjustment for Medicare and other insurers, highlighting Hierarchical Condition Categories (HCC) used to assess clinical complexity and predict costs. Accurate, specific provider documentation using linking terms to show causal relationships and treating current active conditions is stressed to support appropriate coding, reimbursement, and quality metrics.<br /><br />Finally, disclaimers clarify the educational purpose of the content, noting that coding decisions and payment responsibility rest with healthcare providers and organizations.
