Community Option Waiver Providers
The Maryland Department of Health (MDH) is aware of ongoing payment issues affecting providers, particularly concerning National Provider Identifier (NPI) numbers and denied claims for dates of service on or after October 1, 2025. We are actively working to resolve the "provider NPI number is invalid" message.
Additionally, claims currently being denied due to diagnosis codes will require resubmission. Providers must use one of the following diagnosis codes: Z59861, Z59868, or Z59869. Please note that Z5989 is no longer valid for dates of service after September 30, 2025.
