Anticipated changes in the CC/MCC designations were delayed.
EDITOR’S NOTE: Senior healthcare consultant Laurie Johnson reported this story live during Aug. 6 edition of Talk Ten Tuesday. The following is an edited transcript of her reporting.
The Centers for Medicare and Medicaid (CMS) Inpatient Prospective Payment System (IPPS) FY20 Final Rule was released on August 2, 2019. There were some anticipated changes that were a no-show in the 2,273 pages of the final rule that can be found. This article discusses the Medicare Severity Diagnosis Related Groups (MS-DRGs) changes with a focus on the overall changes.
The CC/MCC Re-assignment
The anticipated changes in the CC/MCC designations were delayed. CMS received many comments regarding the suggested 1,492 changes in the CC/MCC designations that appeared in Proposed Rule. Due to the increased comments, CMS decided to make some minor changes to the CC/MCC designations and review the topic for FY21.
The non-CC to CC changes that were finalized include eighteen codes that appear in the Z16 category which covers resistance to various drugs. The Social Determinant of Health code Z59.0 (Homelessness) is still designated as non-CC. There was no additional information on the Social Determinants of Health in this Final Rule.
There appear to be 14,598 CCs and 3,249 MCCs for FY20 including the CC/MCC designations for the new diagnosis codes.
The MS-DRG Changes
The overall relative values for FY20 have increased over the relative values for FY19. There are seven suggested MS-DRG changes that increase over FY19. The table below provides more detail regarding the shifts and specific MS-DRGs with the associated relative weights by topic.

Changes to MS-DRGs 981 – 983 and 987 – 989
CMS routinely reviews the diagnosis and procedure codes that are grouping to the MS-DRGs 981-983 and 987 – 989. These MS-DRGs cover the diagnosis and procedure mismatches. The goal of the annual review is to reduce the number of situations that are assigned to these MS-DRGs.
The following table displays the topics that are covered in the MS-DRGs 981 – 983 and 987-989. Included in the table are a short description of the change, and the MS-DRGs assigned in FY19 with associated relative weight is compared to the proposed MS-DRG assigned in FY20 with the associated proposed relative weight.
