Behavioral health providers, and particularly those treating substance abuse disorders, often face an uphill battle when it comes to getting paid by insurance companies for their services. In this presentation you’ll hear from two different “boots on the ground” perspectives – a biller and an attorney – who will share their insights on best practices, insider tips, and techniques for maximizing your potential for recovery, and minimizing your exposure to insurer allegations of billing fraud.

Topics in this webinar will include:

  1. Creating clean documentation that can stand up to scrutiny and support your claim for payment
  2. Efficient and effective appeals of denied and underpaid claims
  3. Effectively handling insurer audits and pre-payment reviews
  4. Handling “patient financial responsibility” issues including the collection of deductibles, co-payments, and coinsurance
  5. Maintaining organized claims data to drive your business decisions.
