Billing profile setup doesn't clearly explain whether a solo practitioner operating as a PLLC should bill as an Individual (rendering NPI only) or as an Organization (billing/org NPI plus separate rendering NPI), which is confusing for anyone with both NPI types. Suggested fix: add inline guidance or a short decision-tree prompt during billing profile setup that asks about practice structure (solo vs. group, PLLC vs. sole proprietor) and recommends the correct NPI configuration accordingly.
