Will MaineCare accept files with both ICD-9 and ICD-10 codes?
ICD codes are driven by date of service.  If the date of service is prior to 10/01/14, ICD-9 codes should be used, but if the date of service is on or after 10/1/14, ICD-10 codes should be used. MaineCare is able to accept both ICD-9 and ICD-10 codes in the same file, as long as the claim is properly coded with ICD-9 codes for dates of service prior to 10/01/14, and ICD-10 codes for dates of service on or after 10/01/14.

Who is impacted by the transition to ICD-10?
All entities covered under HIPAA must transition to ICD-10.  This includes providers, payers, and clearinghouses.  If you are unsure if you are covered under HIPAA, please check the CMS webpage regarding HIPAA covered entities.

Will providers need new provider agreements because of ICD-10?
No.  Provider agreements do not contain procedure or diagnosis codes; therefore, no changes are necessary.   

Does/will MaineCare use diagnosis codes to adjudicate dental claims?

MaineCare currently does not use diagnosis codes for processing dental claims with the exception of the 101 ANUG diagnosis.  The 2006 ADA form that is currently in use does not have a field for dental diagnosis codes.  MaineCare is currently conducting an adoption analysis of the 2012 ADA form and we will notify providers once a decision has been made concerning implementation.

When will MaineCare be implementing the CDT 2013 codes? 

A message was sent to providers via listserv regarding 2013 dental codes on January 22, 2013.  It stated that code D1203 had been replaced with code D1208.  The remaining 2013 MaineCare covered dental codes will soon be available and MaineCare will notify providers when they can be billed.  You can subscribe to MaineCare email updates on the Mailing List Web Subscription webpage.
