MIPS 2026 Reporting Deadline: A Week-by-Week Checklist for Submission Success

The MIPS 2026 submission window opens January 2, 2027 and closes March 31, 2027. Most penalties don't come from missed measures — they come from the final 60 days. A practice that built a week-by-week checklist hits the 75-point threshold; one that didn't scrambles in late March. Here's the cadence that works.

January (during the performance year start)

Week 1: Lock measure selection. Confirm six quality measures + IA + PI commitments. If you haven't already, see what changed in 2026 MIPS.

Week 2: Configure analytics. Either your EHR's native quality tracker or an external MIPS analytics platform. Validate the denominators against a small known cohort.

Week 3-4: Run your first month's data. The point isn't the rate; it's confirming the pipeline works end-to-end.

Quarterly cadence (Feb-Oct 2026)

Monthly: pull your current composite score and category scores. Look at trajectory, not absolute value.

• If a measure is drifting below benchmark, intervene now — by Q3 the data is set.
• If PI is at zero on any measure, fix it the week you find out. PI floors at zero, and a zero in any measure tanks the category.
• Cost (the only category you don't submit) requires monitoring via your claims feed. MSPB outliers identified in Q2 are recoverable; those identified in Q4 aren't.

November (performance year wrap)

Week 1: Final eligibility review. Confirm no exclusions or special status changes affect your reporting.

Week 2-3: Pre-submission validation. Run every measure against the audit-defensible documentation. The most common late-stage issue: a measure that scored fine all year fails validation because the documentation source changed mid-year (a template update, a new field, a workflow change).

Week 4: Promoting Interoperability final check. Confirm SAFER Guides attestation. Confirm Direct Messaging count. Confirm public health registry connections show successful transmissions.

December (performance year close)

Catch-up window. Patients who can still be screened, still receive an immunization, still complete a depression screening, still receive an AWV — December is the last useful intervention window. Most practices that miss 75 miss it by 2-4 points; December workflow easily moves 5+ points.

January 2027 (submission window opens)

Week 1: Final data pull. Lock the measurement window.

Week 2-3: Internal sign-off. Compliance officer, billing manager, and clinical lead review the submission.

Week 4: Submit. Don't wait for March. Early submission means time to correct if QPP rejects a measure.

March 2027 (deadline)

Submit by March 31. After this date no corrections, no additions, no excuses. The 9% bonus or 9% penalty is locked in.

The pattern that beats the threshold

Practices that consistently hit 75+ share one thing: they configured in January, monitored monthly, and intervened by Q3. The penalty practices share one different thing: they treated MIPS as a March task. The week-by-week version above is how the high-performing group thinks about it.
