Summary
Nevada Medicaid updated rules for DME billing modifiers RB, RR, and MS effective November 18, 2024. Key changes include: RR modifier limited to 10 months rental, these three modifiers cannot be billed together in any combination, and MS modifier cannot be billed with purchase until 6 months after purchase date.
Action Required
Immediately: Billing team must update DME billing rules in system to enforce new modifier restrictions - limit RR modifier to 10 months maximum, prevent billing RB/RR/MS modifiers together for same HCPCS code and month, and block MS modifier with purchase codes until 6 months post-purchase. Update staff training on DME modifier usage to prevent claim denials.
