Medical Necessity & Payment
Why a service gets paid: diagnosis linking, coverage rules, ABNs and denials.
- 23What Medical Necessity MeansThe 'reasonable and necessary' rule, and why it is not the same as MDM.
- 24Linking Diagnoses to ServicesDiagnosis pointers, symptoms vs 'rule out', screening vs diagnostic.
PT-33 - 25NCDs, LCDs & Coverage ArticlesLook up covered diagnoses and frequency limits in the Medicare Coverage Database.
- 26ABN & Modifiers GA, GZ, GX, GYWhen to give an ABN, what makes it valid, and who pays.
