ProviderOne Billing and Resource Guide

A complete guide for using ProviderOne.

Important! On January 1, 2017, the Health Care Authority (HCA) changed the process for managing Apple Health (Medicaid) benefits for clients with other primary health insurance. Learn about these changes.

The ProviderOne Billing and Resource Guide gives step-by-step instruction to help provider billing staff:

  • Find client eligibility for services.
  • Bill in a timely fashion.
  • Receive accurate payments for covered services.

The guide is intended to:

  • Strengthen the current instructions that apply to nearly all types of providers.
  • Respond to provider requests for more step-by-step reference materials for ProviderOne.

Paperless billing has arrived!

On October 1, 2016, the Health Care Authority implemented a paperless billing policy where all Apple Health (Medicaid) providers (excluding Tribal billing offices) are required to submit electronic claims for Apple Health (Medicaid) services. Providers may seek approval to submit paper claims if they are in a temporary or long-term situation outside of their control that precludes submission of claims electronically. 

The agency's Provider Relations team hosted two webinars focused on billing electronically through the ProviderOne portal to assist those providers who have not transitioned to electronic billing. The links to these webinars, the waiver form, and an FAQ on the paperless policy can be accessed below:

Guide updated to reflect paperless billing

As of October 1, 2016, the ProviderOne Billing and Resource Guide no longer contains references to paper claim billing. It is now focused solely on electronic claim submission.
