Step-by-Step Resolution
Steps tailored specifically to this CO-150+N115 combination — not generic advice.
- 1
Review claim submitted for frequency limits listed in LCD and Policy Article and either adjust amounts because of supplier liable or appeal claim with documentation to support medical need
- 2
Consult the Medically Unlikely Edit (MUE) tool to ascertain the maximum allowable units of service that a provider typically reports for a single beneficiary on a given date of service. It's essential to remember that when billing for a 60- or 90-day supply, as permitted by the policy, the claim must feature a narrative in Item 19 of the 1500 hard copy claim form or the 2400/NTE segment of an electronic claim, as stipulated by the Standard Documentation Requirements for claim narratives. This narrative should clearly specify the duration of the supply (either 60- or 90-day supply). In the event that the narrative was omitted from the claim, a reopening process via telephone or in writing will be necessary to append the required narrative
- 3
Examine the claim to confirm the presence of a narrative when it is necessary in Item 19 of the 1500 hard copy claim form or the 2400/NTE segment of an electronic claim. Numerous scenarios necessitate a narrative to offer additional details. An instance of this is seen when submitting the same HCPCS code on multiple lines, where distinct strengths are involved for J codes. Follow the reopening guidelines to resolve
- 4
A Redetermination request may be submitted with all relevant supporting documentation. Noridian encourages Redeterminations/Appeals be submitted using the Noridian Medicare Portal. Review applicable Local Coverage Determination (LCD), LCD Policy Article, and Documentation Checklists prior to submitting request. Noridian encourages Redeterminations be submitted using the Noridian Medicare Portal
