RAI Manual v1.17.1 Update Raises Acute ICD-10 Code Questions

By Caralyn Davis, Staff Writer - September 25, 2019

Last week, the Centers for Medicare & Medicaid Services (CMS) released the long-awaited version 1.17.1 of the Long-Term Care Facility Resident Assessment Instrument 3.0 User’s Manual. One change from the draft version 1.17 manual highlights some ongoing confusion about how to code ICD-10-CM diagnosis codes in MDS items I0020B (ICD Code/Resident’s Primary Medical Condition) and I8000 (Additional Active Diagnoses) to ensure accurate case-mix classification in the Patient-Driven Payment Model (PDPM).

The ICD-10 code entered in I0020B determines a Part A resident’s default primary diagnosis clinical category for the physical therapy (PT), occupational therapy (OT), and speech-language pathology (SLP) payment components under PDPM. In addition, ICD-10 codes entered in I8000 determine whether the resident qualifies for certain comorbidities under the SLP component (identified in Table 14, “SLP-Related Comorbidities,” in the PDPM Calculation Worksheet for SNFs section of chapter 6 in the RAI User’s Manual) or the nontherapy ancillaries (NTA) component (identified in Table 16, “NTA Comorbidity Score Calculation”).
