Featured: OB/GYN 2027 Readiness Demo (2026 vs 2027 comparison)

Step through one fictional maternity claim handled the 2026 way and then the 2027 way. See what changed, hear the payer call, and decide what to do next.

Training illustration only: the claim, rules, and call below are editable training placeholders, not payer policy, coding guidance, or regulatory facts. Always verify current payer and coding guidance.
