To defend against RAC, MAC, or TPE audits, we always fight clinically claim by claim. We show that the clinical records do support the service billed despite what an auditor says. But there are other more broad defenses that apply to providers found in the Social Security Act (SSA), even if the clinical arguments are weak.

When faced with an alleged overpayment, look to the SSA. Within the SSA, we have three, strong, provider defenses:

1. Waiver of liability
2. Providers without fault
3. Treating physician rule

The “waiver of liability” defense provides that, even if payment for claims is deemed not reasonable and necessary, payment may be rendered if the provider did not know, and could not have been reasonably expected to know payment would not be made. SSA, § 1879(a); 42 U.S.C. §1395pp; see also Medicare Claims Processing Manual (CMS-Pub. 100-04), Chapter 30, §20. If a provider could not have been reasonably expected to know payment would not be made as the services were medically necessary and covered by Medicare.

Section 1870 of the SSA states that payment will be made to a provider, if the provider was without “fault” with regard for the billing for and accepting payment for disputed services. As a general rule, a provider would be considered without fault if he/she exercised reasonable care in billing for and accepting payment; i.e., the provider complied with all pertinent regulations, made full disclosure of all material facts, and on the basis of the information available, had a reasonable basis for assuming the payment was correct. Here, there is no allegation of fraud; medically necessary services were rendered. The doctors performed a medically necessary service and should be paid for the service despite nominal documentation nit-picking. The SSA does not require Medicare documents to be perfect; there is no requirement of error-free.

            It is well-settled law that the treating physician’s medical judgment as to the medical necessity of the services provided should prevail absent substantial contradictory evidence. Meaning, the doctor who actually physically or virtually treat the consumer has a better vantage point than any desk review audit. Therefore, substantial deference should be given to the treating physician. This is especially important in proving medical necessity.

Lastly, even though this is not in the SSA, question the expertise of your auditors. If you are an MD and provide bariatric services, the auditor should be similarly qualified. Likewise, a dental hygienist should not audit medical necessity for a dental practice. Even if, clinically, your records are not stellar, you still have the broad legal defenses found in the SSA.
