Updated for the 2027 maternity restructure. The sheet flags all 17 obstetric codes the AMA is deleting on 1 January 2027 alongside the 2026 codes you are billing today — so one reference covers you through the transition.
The 2026 OB/GYN CPT Cheat Sheet is a 2-page reference covering the maternity global package, ultrasound, and the GYN procedure codes your team bills most. Built by AMS Solutions’ AAPC-certified coders who’ve handled OB/GYN billing since 1992.
This sheet covers where OB/GYN revenue actually leaks: incorrect global-package splits when patients transfer mid-pregnancy, missed ultrasound modifiers on multi-gestation pregnancies, and same-day GYN procedure + E/M bundling errors. Print it, post it next to the work queue, save it to your team’s coding folder. Free, no obligation.
Tell us where to send the PDF and we’ll deliver it instantly — plus the 3 most-asked ob/gyn billing questions from our team.
Managing the billing team?
If you run the practice or oversee billing, our guides for owners and managers cover the questions behind the codes: how to tell whether billing is performing, what your days in A/R should be, where revenue leaks, and how to compare billing partners. See resources for practice owners & managers →
When a patient transfers care or changes plans mid-pregnancy, the global package has to be unbundled into its antepartum, delivery and postpartum parts — and billing it as though nothing changed leaves real money uncollected. This sheet shows which codes apply to each segment.
If global-package and obstetric claims are the ones that keep coming back, our medical billing services cover charge entry, denial management, and A/R follow-up without moving your practice off its current system.
If your practice is losing revenue to missing modifiers, prior-auth gaps, or under-coded E/M, we’ll show you exactly where in a free 30-minute review. Call 866-973-2221 or book a 30-minute review.
