Who is eligible for MIPS 164?

All patients undergoing isolated CABG surgery.

Is MIPS 164 the same as MIPS 164?

Yes. CMS uses zero-padded three-digit Quality IDs (164) in official specifications, while clinicians often search for MIPS 164 or Quality ID 164 without the leading zero. Both refer to the same 2026 MIPS quality measure reported through the Quality Payment Program (QPP).

What codes do I submit for MIPS 164: Coronary Artery Bypass Graft (CABG): Prolonged Intubation?

Submission codes: G8569 (Prolonged postoperative intubation (> 24 hrs.) required); G8570 (Prolonged postoperative intubation (> 24 hrs.) not required)

What is the NQF number for MIPS Measure 164?

MIPS Measure 164 is associated with CBE/NQF number 129. It can be reported through the Quality Payment Program (QPP) as a MIPS Clinical Quality Measure (CQM).

How do I report MIPS Measure 164 in 2026?

MIPS Measure 164 (Quality ID 164) is reported through the Quality Payment Program (QPP) as a MIPS Clinical Quality Measure (CQM) via qualified registry, or Medicare Part B claims where applicable.

Is MIPS 164 a topped-out measure?

No, MIPS 164 is not topped out, meaning there is still meaningful performance variation across clinicians.

VBCA Insights

Why This Measure Matters

Patients who need prolonged breathing support after bypass surgery (over 24 hours) face longer ICU stays, higher costs, and worse long-term outcomes. This outcome measure tracks how often your bypass patients avoid this complication. Better performance comes from optimizing anesthesia, surgical technique, and post-operative management to get patients off the ventilator faster. Collaborative protocols between surgery and ICU teams can meaningfully reduce ventilator time.

VBCA is a CMS-approved Qualified Clinical Data Registry (QCDR) that submits MIPS Measure 164 to the Quality Payment Program (QPP). Practices can report this measure as a MIPS Clinical Quality Measure (CQM) or through qualified registry submission.

Clinical Rationale

Based on the STS coronary artery bypass graft (CABG) study population, the morbidity rate associated with prolonged intubation following CABG is 5.96%. Also, prolonged ventilation (defined as > 24 hours) was an independent predictor for readmission to the ICU following CABG surgery (OR=10.53; CI: 6.18 to 17.91). Shorter ventilation times are linked to high quality of care (i.

e., reduced in-hospital and operative mortality, as well as better long-term outcomes as compared to prolonged ventilation).

Clinical Recommendations

Extubation greater than (>) 24 hours postoperatively is considered a “pulmonary complication”. Patients who were extubated more than 24 hours after surgery had a longer duration of hospital stay and a greater incidence of postoperative complications.

Implementation Notes

This measure contains one strata defined by a single submission criteria. This measure produces a single performance rate. For the purposes of MIPS implementation, this procedure measure is submitted each time a procedure is performed during the performance period. This is an inverse measure which means a lower calculated performance rate for this measure indicates better clinical care or control.

The “Performance Not Met” numerator option for this measure is the representation of the better clinical quality or control. Submitting that numerator option will produce a performance rate that trends closer to 0%, as quality increases. For inverse measures, a rate of 100% means all of the denominator eligible patients did not receive the appropriate care or were not in proper control.
