Have Claims Questions?

Your first line for help for claims questions is your Medicare Administrative Contractor; They’ll offer their regular customer service support and respond quickly;

Note that MACs cannot respond to questions about Medicaid or Commercial health plans.
  • If you have a Medicaid claim question, contact your State Medicaid Agency.
  • If you have a commercial or private health plan claim question, please contact your health plan directly.

Have Other Concerns or Issues?

Contact your CMS Regional Office for questions. The Regional Offices of the Centers for Medicare & Medicaid Services are the agency’s state and local presence. Regional field staff work closely with beneficiaries, health care providers, state governments, CMS contractors, community groups and others to provide education and address questions. Providers may send ICD-10 inquiries to the appropriate regional office using the email address on the CMS Regional Offices page.
