Choose the right perspective
Match the person's seat to your question, since plan-side revenue and submission leaders see a different part of risk adjustment than coding and documentation leaders. Check the dates on each role so that a question about current CMS rules goes to someone who holds a risk adjustment role today.
Questions to take into the conversation
- 01How did you organize chart review, coding and encounter data submissions so that RAF scores stayed accurate and defensible in a RADV audit?
- 02How did you estimate and communicate the revenue impact of a CMS-HCC model change to finance and leadership?
- 03How do you split risk adjustment work between the plan, provider groups and outside coding vendors, and what would you change about that split?
