On February 10, 2022, as part of a regular annual update, we updated the rates for MaineCare Benefits Manual, Chapter II, Section 4, Ambulatory Surgical Center Services, in MIHMS retroactively to January 1, 2022.  

See this spreadsheet for the list of new codes with their rates, which is also available on the Codes & Rates webpage, or you can see all the codes and rates in the fee schedule. 

Adjustments for affected claims:  

• If you have been billing these codes at a higher rate than is indicated in the spreadsheet, we will reprocess your claims and no provider action is needed.    

• If you have been billing these codes at a lower rate than is indicated in the spreadsheet, please adjust the affected claims. Providers will have 120 days from the date of this notice to submit corrected adjustments; please focus on the oldest dates of service first.  

For guidance about adjusting verses straight reversing claims and instructions on how to do each, see the How to Adjust Claims for Retro Rate Increases (PDF).
