Keep Your ICD-10-CM Processes Up to Date

April 14, 2023


This presentation will focus on how to keep the resident medical record diagnoses lists up to date. ICD-10-CM codes impact resident medical records- accurate diagnosis codes are required. ICD-10-CM codes also impact payment. Invalid or deleted codes appearing on UB-04s will cause the claims to be rejected. The necessity for accuracy of diagnosis coding in medical records cannot be overstated.

This presentation will also offer guidance for determining resident diagnoses and diagnosis codes on admission to the nursing home, at least quarterly when the residents’ MDS assessments are completed, and annually when new ICD-10-CM codes are added/updated/deleted. There will be explanations regarding how to use the Conversion Files, the Resident Electronic Health Record Reports, and the Addenda Files for the Alphabetic Index, Tabular List, Neoplasm Table, Tables of Drugs and Chemicals, and External Cause Index to identify codes that are no longer valid, have been deleted or require a higher degree of specificity. The presentation will also explain the correct method to query physicians to obtain more specific diagnoses or to clarify a diagnosis when the documentation has not been clear.

Learning Objectives:
1. Identify which step should be taken when the physician documentation is not clear, or lacks required specificity.
2. Describe how primary diagnoses ICD-10-CM codes on claims can cause claim rejection even though the CMS PDPM file maps the diagnosis to payment.
3. State how the Conversion Table can be used to assist staff to keep resident ICD-10-CM codes up to date.
