2024 MIPS Measure #490: Appropriate Intervention of Immune-Related Diarrhea and/or Colitis in Patients Treated with Immune Checkpoint Inhibitors



MIPS Clinical Quality Measures (CQMS)



‌Percentage of patients, aged 18 years and older, with a diagnosis of cancer, on immune checkpoint inhibitor therapy, and grade 2 or above diarrhea and/or grade 2 or above colitis, who have immune checkpoint inhibitor therapy held and corticosteroids or immunosuppressants prescribed or administered.


This measure is to be submitted a minimum of once per episode for patients with a diagnosis of cancer and on immune checkpoint inhibitors and who have grade 2 or above diarrhea and/or grade 2 or above colitis seen during the performance period. This measure may be submitted by Merit-based Incentive Payment System (MIPS) eligible clinicians who perform the quality actions described in the measure based on the services provided and the measure-specific denominator coding.

‌Measure Submission Type

Measure data may be submitted by individual MIPS eligible clinicians, groups, or third-party intermediaries. The listed denominator criteria are used to identify the intended patient population. The numerator options included in this specification are used to submit the quality actions as allowed by the measure. The quality data codes listed do not need to be submitted by MIPS eligible clinicians, groups, or third-party intermediaries that utilize this modality for submissions; however, these codes may be submitted for those third-party intermediaries that utilize Medicare Part B claims data. For more information regarding Application Programming Interface (API), please refer to the Quality Payment Program (QPP) website.

‌NOTE: Patient encounters for this measure conducted via telehealth (including but not limited to encounters coded with GQ, GT, 95, POS 02, POS 10) are allowable.


Patients 18 years and older, with a diagnosis of cancer and on immune checkpoint inhibitors and who have grade 2 or above diarrhea and/or grade 2 or above colitis


Episode Onset of grade 2 or above diarrhea or grade 2 colitis or above until resolution.

Immune checkpoint inhibitors Class of medications that prevent tumors from “hiding” or “evading” the body’s natural immune system. This is a form of cancer immunotherapy. Immune checkpoint inhibitor medications include PD-1 inhibitor drugs, PD-L1 inhibitor drugs, and CTLA-4 inhibitor drug.

  • PD-1 inhibitors drugs include: Pembrolizumab, Nivolumab, Cemiplimab
  • PD-L1 inhibitors drugs include: Atezolizumab, Avelumab, Durvalumab
  • CTLA-4 inhibitor drug includes: Ipilimumab

Grade 2 Diarrhea 4-6 bowel movements above baseline per day. Moderate increase in ostomy output compared to baseline; limiting instrumental ADL.

Grade 3 Diarrhea Increase of ≥ 7 stools per day over baseline; hospitalization indicated; severe increase in ostomy output compared to baseline; limiting self-care ADL.

Grade 4 Diarrhea Life-threatening consequences; urgent intervention indicated.

Grade 2 Colitis Abdominal pain, mucus or blood in stool.

Grade 3 Colitis Severe abdominal pain; peritoneal signs.

Grade 4 Colitis Life-threatening consequences; urgent intervention indicated.

DENOMINATOR NOTE: *Signifies that this CPT Category I code is a non-covered service under the Medicare Part B Physician Fee Schedule (PFS). These non-covered services should be counted in the denominator population for MIPS CQMs.
