MSA 21-03

Effective date
Jan 1, 2021
Identified
Jun 20, 2026

Summary

Effective for dates of service on and after January 1, 2021, Michigan Medicaid aligned office and outpatient evaluation and management levels 99202 through 99215 with the 2021 AMA CPT guidelines, so practitioners may select the level based on medical decision making or total time on the date of the encounter. The same date brought the annual HCPCS update, under which any new procedure code not listed will not be covered at this time except for reporting codes, and codes marked with an asterisk require prior authorization. Other changes in this bulletin, including retroactive coverage dates from October 1 through November 21, 2020 and COVID-19 specimen collection diagnosis codes, have dates that have already passed, so check current applicability before acting on them.

What to do

Action · 9 steps
01Already effective January 1, 2021: Billing team, bill office and outpatient E/M services 99202 through 99215 using the level of medical decision making or the total time on the date of the encounter.
02Do not bill new procedure codes that are not listed in the bulletin's 2021 HCPCS update, except reporting codes, because they will not be covered at this time.
03Codes marked with an asterisk require prior authorization before billing, for example J9144 for physicians and practitioners and 81168 for laboratory services.
04Newly covered laboratory codes 81415, 81416, 81417 and 0037U require prior authorization.
05Do not report the HCPCS codes the bulletin lists as discontinued effective December 31, 2020 or September 30, 2020.
06Already effective March 1, 2021: For COVID-19 specimen collection, report procedure code 99000 or 99001 with diagnosis Z20.822 or Z11.52 for dates of service on or after March 1, 2021.
07Diagnoses Z03.818, Z11.59 and Z20.828 are no longer eligible for Medicaid reimbursement on COVID-19 specimen collection claims for dates of service after February 28, 2021.
08COVID-19 specimen collection is reimbursed as a separate service only when no other evaluation and management service or eligible qualifying clinic visit related to COVID-19 testing is provided on the same date of service.
09Historical items: retroactive coverage listed for dates of service from October 1 through November 21, 2020, and place of service 60 for claims processed on or after October 1, 2020, have elapsed, so check current applicability rather than completing those past dates.
