The “Coding Tips and Billing Reminders—Fall 2024” document from CHPW outlines essential guidelines for accurate coding and billing practices across all CHPW lines of business, including Apple Health (Medicaid), Medicare Advantage, and Individual and Family Cascade Select is now available.
Key coding considerations address the classification and reporting of Acute Myocardial Infarctions (AMI) and Cerebrovascular Accidents (CVAs), emphasizing the importance of timely documentation and appropriate coding rules, such as the “4-week rule” for AMIs and the specific criteria for reporting strokes, including the necessity for confirmation through diagnostic studies in acute care settings.
In relation to coding practices, the document highlights the correct applications of Modifier 25 and its potential for misuse, clarifying that it should only be used when there is a significant, separately identifiable evaluation and management service performed on the same day as another procedure.
Detailed examples demonstrate inappropriate uses of this modifier to prevent claims denials. Additionally, specific guidance around coding for multiple deliveries is provided, particularly for cases involving twins or multiple gestations, to navigate billing complexities effectively.
The document also includes critical billing reminders covering hypertension coding practices and updates to the ICD-10-CM guidelines, pain management procedure billing specifics, and requirements for prolonged services tied to different lines of business.
Notably, it covers the updates to swing bed claims under Apple Health, emphasizing the necessity of including a date of service segment for institutional claims per Washington State Health Care Authority guidelines.
