In the previous two parts of this four part series, we discussed the new ICD-10-CM diagnosis code changes and ICD-10-PC procedure code changes.  In this session we will review the major IPPS changes for FY2021.

IPPS Changes Financial

On September 2, 2020, CMS published the Final Rule for IPPS (CMS-1735F) It was a month late due to the COVID-19 pandemic.   FY2021 IPPS Final Rule

Acute care hospitals that report quality data and that are meaningful users of EHRs will receive approximately a 2.7% increase in Medicare operating rates. Hospitals that do not submit quality data would lose 1/4 (-25%)  of the market basket update (of 2.7% as above) and hospitals that are not meaningful users of EHRs will be subject to a 3/4 )_0.75%)reduction of the market basket for FY 2021.

CMS is finalizing an alternative pathway for certain antimicrobial products based on significant concerns with the ongoing public health crisis represented by antimicrobial resistance.

CMS is projecting that with the 2.7% increase and other changes to IPPS policies it will boost total IPPS payments in FY2021 by roughly $3.5 billion.

There were no new changes to the Post-Acute Care Transfer Policy for FY2021.

Quality Measures

Hospitals are required to report measures and meet the administrative requirements of the IQR program to avoid having their annual market basket update reduced by one quarter.  The IQR also includes requirements to report electronic clinical quality measures (eCQMs) that align with the eCQM reporting requirements in the Promoting Interoperability Program. (Generated by provider’s E.H.R.) See https://www.cms.gov/Regulations-and-Guidance/Legislation/EHRIncentivePrograms/ClinicalQualityMeasures.html

No new measures for IQR in FY2021.  CMS did make some changes to the hospital reporting process and reporting periods of eCQM data and streamlining hospital IQR Program validation processes. See this link for details of these changes:  https://www.cms.gov/newsroom/fact-sheets/fiscal-year-fy-2021-medicare-hospital-inpatient-prospective-payment-system-ipps-and-long-term-acute

For the Hospital-Acquired Condition (HAC) Reduction Program, no changes to the scoring methodology will be made in FY2021.

For the FY 2021 IPPS/LTCH PPS Final rule, CMS is finalizing to automatically adopt applicable periods (i.e., performance periods for measures used in the Program) beginning with the FY 2023 program year and all subsequent program years and update the definition of applicable period at 42 CFR 412.152 to align with the automatic adoption proposal.

DRG Changes

There were several changes involving DRGs.    Below are the changes.

Pre-MDC: Allogeneic Bone Marrow Transplant:  CMS finalizing to re-designate MS-DRG 014 (Allogeneic Bone Marrow Transplant), MS-DRG 016 (Autologous Bone Marrow Transplant with CC/MCC or T-Cell Immunotherapy), and MS-DRG 017 (Autologous Bone Marrow Transplant without CC/MCC) from surgical MS-DRGs to medical MS-DRGs.

  • Bone marrow transplants involve transfusions not surgery and do not need an operating room.
  • CMS will re-designate the 8 (302—-) transfusion codes to non-OR procedures.

 

Pre-MDC:  Chimeric Antigen Receptor(CAR) T-cell Therapies and its own DRG:  CMS finalized  to create a new MS-DRG 018, CAR T cell Immunotherapy for CAR T Cell Therapy (Chimeric Antigen Receptor) cases and remove them from Pre-MDC MS-DRG 016 (Autologous Bone Marrow Transplant with CC/MCC or T-Cell Immunotherapy)

  • XW033C3, Introduction of engineered autologous chimeric antigen receptor t-cell immunotherapy into peripheral vein, percutaneous approach, new technology group 3
  • XW043C3, Introduction of engineered autologous chimeric antigen receptor t-cell immunotherapy into central vein, percutaneous approach, new technology group 3
  • Examples are YESCARTA®  and KYMRIAH®.

Changed the name of Pre-MDC MS-DRG 016 (Autologous Bone Marrow Transplant with CC/MCC or T-Cell Immunotherapy) by removing the “or T-Cell Immunotherapy.

MDC 1: Carotid Artery Stent:  Six codes below were left out last year of MS-DRGS 034, 035, and 036 (Carotid Artery Stent Procedures with MCC, with CC, and without CC/MCC, respectively).  So this year they were added into DRGS 034, 035, 036.  Eight codes grouping to MS-DRGS 981, 982, 983 moved to DRGS 034, 035, 036. For FY 2021, CMS is also adding the 36 ICD-10-PCS that are currently assigned in MDC 05 in MS-DRGs 252, 253, and 254 to MS-DRGs 034, 035, and 036 in MDC 01. (Dilation of internal, external carotids with various # of stents)

MDC 3: TMJ Replacements:  For TMJ replacements, CMS is creating two new base MS-DRGs, 140 and 143, with a three-way severity level split for new MS-DRGs 140, 141, and 142 (Major Head and Neck Procedures with MCC, with CC, and without CC/MCC, respectively) and new MS-DRGs 143, 144, and 145 (Other Ear, Nose, Mouth And Throat O.R. Procedures with MCC, with CC, and without CC/MCC, respectively)  See procedure codes listed in Table 6P.2c for the codes. See table 6P.2a and table 6P.2b for the list of procedure codes we are finalizing for reassignment from MS-DRGs 129, 130, 131, 132, 133, and 134 to each of the new MS-DRGs.

MDC 5: Left Atrial Appendage Closure (LAAC) (i.e. WATCHMAN™:  CMS is reassigning ICD-10-PCS codes 02L70CK, 02L70DK, and 02L70ZK from MS-DRGs 250 and 251 (Percutaneous Cardiovascular Procedures without Coronary Artery Stent with and without MCC, respectively) to MS-DRGs 273 and 274 (Percutaneous and Other Intracardiac Procedures with and without MCC, respectively).

MDC 5: Cardiac Contractility Device:  CMS is adding the following 24 ICD-10-PCS code combinations to MS-DRGs 222, 223, 224, 225, 226 and 227. CMS will delete the 12 clinically invalid code combinations from the GROUPER logic of MS-DRGs 222, 223, 224, 225, 226 and 227 that describe the insertion of contractility modulation device and the insertion of a cardiac lead into the left ventricle.  Previously, the MS-DRG GROUPER logic required the combination of the CCM device codes and a left ventricular lead to map to MS-DRGs 222, 223, 224, 225, 226 and 227. The requestor stated the CCM device is contraindicated in patients with a left ventricular lead. But some patients can’t take the left ventricle lead however the cases should still group to DRS 222-227.  That is what they are correcting here. Many of these will be outpatient but some are inpatient which is why the DRG logic was corrected.  It is corrected so that it can be the device PLUS right ventricular AND / OR left ventricular lead to the drgs 222-227.

MDC 8: Hip and Knee Joint Replacements with Oxidized Zirconium:  CMS is creating new MS-DRG 521 (RW 3.0652) (Hip Replacement with Principal Diagnosis of Hip Fracture with MCC) and new MS-DRG 522 (RW 2.1943) (Hip Replacement with Principal Diagnosis of Hip Fracture without MCC). The basis of this request was to better reimburse hospitals for using Oxidized zirconium bearing surfaces since the long-term outcomes are better for these patients.   The new DRG without MCC has a higher relative weight than old DRG 470. Previously these cases grouped to MS-DRGs 469 (RW 3.0989), 470 (RW 1.9104) Major hip/knee joint replace or reattach lower extremity, with or without MCC.  Refer to Table 6P.1d for a list of procedure codes and Table 6P.1e for a list of diagnosis codes.

MDC 11: Kidney and Urinary Tract/Kidney Transplants:  New this year in Pre-MDC MS-DRG and new split DRGs:

  • Pre-MDC MS-DRG 019 SIMULTANEOUS PANCREAS AND KIDNEY TRANSPLANT WITH HEMODIALYSIS  6.6601
  • MS-DRG 650 KIDNEY TRANSPLANT WITH HEMODIALYSIS WITH MCC       4.5091
  • MS-DRG 651 KIDNEY TRANSPLANT WITH HEMODIALYSIS WITHOUT MCC   3.7018
  • MS-DRG 652 KIDNEY TRANSPLANT   3.1911

Designating procedure codes 5A1D70Z, 5A1D80Z, and 5A1D90Z that describe hemodialysis as non-O.R. procedures affecting the MS-DRG.

Also, CMS is reassigning ICD-10-CM diagnosis codes T82.41XA, T82.42XA, T82.43XA, and T82.49XA from MDC 05 in MS-DRGs 314, 315, and 316 (Other Circulatory System Diagnoses with MCC, with CC, and without CC/MCC, respectively) to MDC 11 (Diseases and Disorders of the Kidney and Urinary Tract) assigned to MS-DRGs 673, 674, and 675 (Other Kidney and Urinary Tract Procedures with MCC, with CC, and without CC/MCC, respectively) and 698, 699, and 700 (Other Kidney and Urinary Tract Diagnoses with MCC, with CC, and without CC/MCC, respectively).

Also CMS is adding ICD-10-CM codes E09.22, E10.22, E11.22, and E13.22, when reported with a secondary diagnosis of N18.5 or N18.6, to the list of principal diagnosis codes in the subset of GROUPER logic in MS-DRGs 673, 674, and 675 that recognizes the insertion of totally implantable vascular access devices or tunneled vascular access devices as an inpatient procedure for the purposes of hemodialysis.

CMS is also adding ICD-10-CM codes T86.11, T86.12, T86.13, and T86.19 (Kidney transplant complications) to the list of principal diagnosis codes in this subset of GROUPER logic in MS-DRGs 673, 674, and 675.

CMS will remove ICD-10-CM codes I12.9, I13.10, N18.1, N18.2, N18.3, N18.4, and N18.9 from the subset of GROUPER logic in MS-DRGs 673, 674, and 675 that recognizes the insertion of totally implantable vascular access devices or tunneled vascular access devices as an inpatient procedure for the purposes of hemodialysis.  (Conditions not typically addressed by the devices)

MDC 17: Myeloproliferative Disease – IVC Filter:  Given the similarity in factors such as complexity, resource utilization, and lack of a requirement for anesthesia administration between all procedures describing insertion of a device into the inferior vena cava, it would be more appropriate to designate 06H03DZ, Insertion of Intraluminal Device into Inferior Vena Cava, Percutaneous Approach as Non-O.R. procedure. Therefore, we are removing ICD-10-PCS procedure code 06H03DZ, as an O.R. procedure. Under this change, these procedures would no longer impact MS-DRG assignment.  06H00DZ and 06H04DZ will remain OR procedures.

OR to Non-OR and Vice Versa DRG Changes

Many changes were made that involved cases that grouped to DRGs 981, 982 and 983.  The cases were changed out of those DRGs to DRGs within the proper MDC.   Also several procedures were either changed to OR procedure or removed as OR procedures. The lengthy list is:

  • K61.31, Horseshoe Abscess with Drainage 0J9B0ZZ (Drainage of perineum subcutaneous tissue and fascia, open approach) from MS-DRGs 987, 988, and 989 (Non-Extensive O.R.

  • Reassign cases for R04.0, Epistaxis, hemorrhage of the nose when reported with a procedure
    • 03LM3DZ (Occlusion of right external carotid artery with intraluminal device, percutaneous approach),
    • 03LN3DZ (Occlusion of left external carotid artery with intraluminal device, percutaneous approach), or
    • 03LR3DZ (Occlusion of face artery with intraluminal device, percutaneous approach)

Previously these grouped to MS–DRGs 981, 982, and 983 (Extensive O.R. Procedure Unrelated to Principal Diagnosis with MCC, with CC, and without CC/MCC, respectively)
  • Reassign three procedure codes below from MS-DRGs 981, 982, and 983 (Extensive O.R.

  • Whew!

Other Changes

Several of the surgical hierarchies were changed to accommodate the changes to the kidney transplant DRGS and new MS-DRGs as added above.

Several changes were made to the Medicare Code Editor (MCE). For example, codes for age-related osteoporosis with current pathological fracture (M80.0—) were added to those that are Adult Only diagnoses.  Adding the five new obstetric diagnoses to female only edit AND age conflict edit, patient must be 9 to 64 years of age.  Several codes were added to the unacceptable PDX edit to include new manifestation codes.

MCC/CC Severity Levels

Perhaps the biggest surprise was CMS’s decision to NOT change any diagnoses on the MCC list or CC list.  Only the expanded (new) codes for FY2021 were added.  Coders can review tables 6I.1, 6I.2, 6J.1 and 6J.2 for these additions and deletions.

So there you have it for a summary of the IPPS FY2021 changes.  Stay tuned….. In the final Part 4 of this series, the New Technology Add-On Payments (NTAP) will be reviewed in detail.
