This Livewire page documents Connecticut guidance stating ABI service providers may enroll and submit claims without an NPI, while ABI Resources voluntarily uses one. Review seven fields: provider legal name, state enrollment ID, NPI if applicable, taxonomy, service location, ownership, and claim submitter. Federal rules require an NPI for covered health care providers and allow eligible non-covered providers to obtain one; exact coverage depends on the entity and transactions. A state-assigned identifier is not proof of secrecy, weak oversight, fraud, or improper billing. An NPI can improve cross-system matching, but it does not prove qualification, service quality, ownership, or payment accuracy. Compare the Connecticut workshop, current enrollment record, NPPES data, and claims policy. Review the provider-identity record at david-medeiros.com/npi-record.
