Our Story

ACRS, formally known as Woodall & Broome Hospital Bill Negotiations & Claims Review Services, was an extended service of Woodall & Broome Anti-Fraud and Compliance Company. In 2016 Advanced Claims Review Specialists (ACRS) was formed as its own company after seeing the growing opportunity to fill expanded needs in the medical cost containment industry with our personal approach and evidence-based analysis of medical bills, records and itemized charges.

Our mission is to provide superior and unrivaled services for our clients through our highly experienced, credentialed, and dedicated staff of professionals using clinical dialogue and industry leading software to build trust with clients and providers to maximize savings.

What Makes Us Different

Medical bills, provider bills, and facility bills are all prone to error. Whether it’s improper codes, upcharges, unrelated services, duplications or other mistakes, you need a medically-trained and experienced analyst to know what to look for, where to look, and what needs to be corrected, eliminated, or challenged. Simply relying on industry software to perform this complex task leaves you vulnerable and likely to pay a greater percentage of billed charges than may be necessary. The expert analysts at ACRS provide this additional layer of protection and work with our negotiators to craft the medical arguments that are used to begin a direct conversation with the provider. At ACRS we call this unique point of difference “clinical dialogue”.

Clinical Dialogue

At ACRS we understand the challenges that surround both sides of the conversation, which is our clients’ need to save money on their claims as well as the providers’ need to collect money for services rendered. The “slash and burn” technique used by many companies in medical bill review involves cutting a medical bill down based on software review and sending in an unsubstantiated and greatly reduced amount for payment in hopes that the facility or provider will accept it. In the long run this process leaves reconsiderations, liens, and lawsuits in their wake and just doesn’t work!

ACRS believes that an actual phone conversation with the provider about the facts and specific issues related to the medical bills is the proven road to take. Clinical dialogue creates trust, shows respect for others in their position, and over time builds rapport and relationships. Once the negotiated amount is agreed upon by both parties, a simple financial and binding agreement is signed and recommendation for payment is made. Since our inception in 2007 we have NEVER had a single reconsideration, lien, or lawsuit as a result of this process!

A primary outcome derived from our clinical dialogue and treating providers as professionals is trust. This trust builds rapport and relationships with those providers. It is those relationships that continue to bear fruit in the form of their willingness to flex, compromise, and provide additional cost savings for our clients. ACRS builds relationships with providers and facilities around the country on a daily basis, and our clients reap the benefits!
