A physician or clinical provider of care may have a completely different understanding, interpretation, and definition of medical necessity than the patient or a third-party insurance. Lori-Lynne A. Webb, CPC, CCS-P, CCP, COBGC, CHDA, explains the differences in the definition and application of the term medical necessity.
Just because a physician considers a service or procedure medically necessary doesn't mean insurance carriers will pay for it. When a service or procedure is not covered, facilities must provide patients with an Advanced Beneficiary Notice of Noncoverage (ABN). Judith Kares, JD, CPC, and Jacqueline Woeppel, MBA, RHIA, CCS, explain limits on liability and what modifiers to use with ABNs.
