A new Centers for Medicare & Medicaid Services guide provides specific Medicare and Medicaid contacts for health care providers with questions following the Oct. 1 transition to ICD-10. Claims-related questions should be directed to the provider’s Medicare Administrative Contractor or state Medicaid agency before the CMS ombudsman, who will typically respond within three business days, the guide notes. Effective Oct. 1, health care claims must include ICD-10 codes for medical diagnoses and inpatient hospital procedures. For more on the transition to ICD-10, visit www.aha.org and www.cms.gov
