2027 Maternity Code Payment Rates: What the Final Rule Pays for Labor, Delivery, and Prenatal Care

What will Medicare pay for maternity care under the 2027 final rule?

As of November 2026, the CY 2027 Physician Fee Schedule final rule is a Medicare payment rule that adopts the new unbundled maternity CPT codes starting January 1, 2027, raises work values for labor and delivery codes 15% above the AMA RUC recommendations, and rejects the G-codes CMS floated to keep global billing. A routine vaginal delivery, CPT 59431, pays about $443.42 nationally.

• No Medicare G-codes: CMS did not finalize the 15 proposed G-codes, so Medicare and most other payers will use the same new CPT maternity codes in 2027.
• Episode payment now varies: An average-risk pregnancy billed visit by visit can pay less than the old global code, while a higher-risk pregnancy with more visits can pay more.
• 2026 pregnancies get a bridge: CMS issued HIPAA enforcement discretion letting payers accept the 2026 global codes for episodes of care that began in 2026.

What CMS Finalized on November 4, 2026

The Centers for Medicare and Medicaid Services released the CY 2027 Physician Fee Schedule final rule on November 4, 2026. The CMS fact sheet on the final rule covers the headline payment changes, and the maternity decisions appear in the rule text, Federal Register document 2026-22743. Three decisions matter most to obstetric practices.

First, CMS adopted the new maternity code set built at the January 2026 AMA RUC meeting, which deleted 17 legacy codes, created 12 new codes, and revised 6. The global obstetric codes such as 59400, 59510, 59610, and 59618, which bundled 12 prenatal visits with delivery and postpartum care, give way to separately reported prenatal and postpartum visits, per-day labor management codes 59080 through 59083, and delivery-only codes such as 59431, 59432, 59502, and 59503.

Second, CMS increased the work relative value units for the labor and delivery codes by 15% above what the RUC recommended. The agency explained that the RUC’s budget neutrality math assumed 12 prenatal visits per pregnancy, while the May 2025 ACOG clinical guidance describes a sample schedule of 8 visits for average-risk pregnancies and 13 for higher-risk ones. CMS removed four assumed visits from the calculation and moved those relative value units into labor and delivery. CMS stressed it is not endorsing fewer prenatal visits.

Third, CMS declined to create the 15 HCPCS G-codes it had floated in July to preserve global billing for Medicare. Almost all commenters opposed them. The American College of Obstetricians and Gynecologists responded in a November 5, 2026 statement on the final rule. CMS also noted HIPAA enforcement discretion allowing covered entities to keep using the 2026 maternity codes after January 1, 2027 for episodes of care that started in 2026.

How much do the new 2027 maternity codes pay?

At 2027 national facility rates, CPT 59431 for a vaginal delivery pays about $443.42, 59502 for a primary cesarean pays about $680.31, and 59503 for a repeat cesarean pays about $838.56. Labor management is billed per day, from about $166.73 for a straightforward subsequent day to about $255.48 for a complex initial day.

CPT code	Service	2027 work RVU	2027 national rate
59080	Initial day labor management, straightforward	4.03	$193.81
59081	Initial day labor management, complex	5.18	$255.48
59082	Subsequent day labor management, straightforward	3.45	$166.73
59083	Subsequent day labor management, complex	4.83	$238.52
59431	Vaginal delivery	9.20	$443.42
59432	Vaginal delivery after previous cesarean	10.35	$502.81
59502	Cesarean delivery, primary	13.80	$680.31
59503	Cesarean delivery, repeat	16.86	$838.56
59434	Repair of fourth-degree laceration	4.14	$205.23

Rates are national facility amounts calculated from the CY 2027 Addendum B relative value units and the $32.6286 nonqualifying APM conversion factor, before geographic adjustment. Facility rates apply because deliveries occur in the hospital. Prenatal and postpartum visits are reported with office E/M codes and modifier TH, so they follow the office visit rates: in 2027, CPT 99213 pays about $92.01 and 99214 about $131.17 in the office setting.

Medicare covers relatively few pregnancies, but these values still matter. Many Medicaid programs and commercial contracts price services as a percentage of the Medicare fee schedule, so the new relative values flow through to most of an obstetric practice’s payer mix. Whether your team works from payer manuals or from references like our OB/GYN Red Book guide, treat the 2027 values as the new baseline for every contract review.

Does unbundled billing pay more or less than the global package?

It depends on the pregnancy. Using 2027 national rates, an average-risk vaginal delivery with 8 prenatal visits pays about $1,543, compared with about $2,120 for the legacy global code 59400. A higher-risk repeat cesarean with 13 prenatal visits and two labor days pays about $3,208, compared with about $2,384 for 59510.

Scenario	Services billed in 2027	Unbundled total	2027 legacy global code
Average-risk vaginal delivery	99204 plus 7 visits at 99213, 59080, 59431, 1 postpartum visit at 99213	$1,543	$2,120 (59400)
Higher-risk repeat cesarean	99204 plus 12 visits at 99214, 59081, 59083, 59503, 1 postpartum visit at 99214	$3,208	$2,384 (59510)

These are illustrative episodes built from CMS’s 2027 national rates, with prenatal and postpartum visits billed as office E/M services with modifier TH and labor and delivery at facility rates. Real episodes will vary with visit levels, the number of labor days, and the payer’s fee schedule. The comparison shows the core shift: payment now follows the care actually delivered, so documentation of every visit level and every labor day decides what a pregnancy is worth.

CMS acknowledged in the rule that some commenters expect certain scenarios to pay less than the global codes, and said it may refine values in future rulemaking. Trade coverage has raised a related concern for employed physicians. Medical Economics reported on November 5, 2026 that OB/GYNs paid on work relative value units may see their productivity numbers fall in 2027, depending on their patient mix.

The most common issue we see providers run into with a change like this is assuming the old global payment is the floor. For an average-risk panel, it is not. Practices with mostly uncomplicated pregnancies need to capture every billable visit at the correct level, and they need to know which payers have loaded the new codes.

What should OB/GYN practices do before January 1, 2027?

OB/GYN practices should load the new maternity codes and 2027 rates, build E/M and modifier TH templates for prenatal and postpartum visits, tag every pregnancy that began in 2026, confirm each payer’s business rules for those episodes, and model revenue for their own risk mix before January.

1. Load CPT 59080 through 59083, 59431, 59432, 59502, 59503, and the revised maternity codes into your charge master.
2. Build prenatal and postpartum visit templates that pair office E/M codes with modifier TH and pregnancy diagnosis codes.
3. Flag every patient whose pregnancy began in 2026 so the billing team applies the correct code set to each episode.
4. Request written business rules from each payer on whether it will accept 2026 global codes for those episodes after January 1.
5. Document each labor day separately, with the complexity level, since labor management is now billed per day.
6. Model 2027 revenue for your own mix of average-risk and higher-risk pregnancies using your contracted rates.
7. Review physician compensation plans tied to work relative value units before the first 2027 deliveries.

The fourth step is the one most likely to go wrong. CMS said payers and health plans may issue business rules before January 1, 2027 telling providers and clearinghouses how to bill episodes that begin in 2026 and end in 2027. Some will accept the 2026 global codes for those patients, and some may expect the new codes for 2027 dates of service. Providers often come to us after a code transition has already stalled claims for weeks because nobody confirmed each payer’s position in writing.

Common Misreadings of the Final Rule

The first misreading is that Medicare will keep global billing through G-codes. CMS considered that option, sought comment, and did not finalize it. Medicare will use the new CPT maternity codes in 2027, which removes the dual-system risk that dominated discussion after the July proposal.

The second misreading is that the 15% increase means a 15% raise for obstetrics. The increase applies to the work values of the labor and delivery codes only, and it was funded by assuming fewer prenatal visits within the same budget-neutral code family. Prenatal visits are paid at standard office E/M rates, which fall slightly in 2027 with the conversion factor cut.

The third misreading is that CMS now limits prenatal visits to 8 or 13. It does not. CMS used ACOG’s sample schedule only to recalculate utilization and stated that it is not specifying a maximum number of antepartum or postpartum visits. Every visit still has to be reasonable and necessary and documented as such.

The fourth misreading is that the change touches every OB/GYN service. Gynecologic codes such as CPT 76830 transvaginal ultrasound are outside the maternity code family. The same is true of screening diagnosis codes such as Z11.3 for sexually transmitted infection screening, which still attach to the prenatal or gynecologic visit where the screening occurs.

Finally, enforcement discretion is not automatic payer acceptance. It allows the 2026 codes to be used; it does not require any payer to accept them. Each plan’s business rules control what actually pays.

In-House Billing vs. an OB/GYN Billing Partner

The end of global billing multiplies the work behind every pregnancy. One global claim becomes a series of visit claims, labor-day claims, a delivery claim, and postpartum claims, each with its own codes, modifiers, and diagnosis. Add payer-by-payer rules for pregnancies that began in 2026, and a small in-house team is running two maternity billing systems at once during the first half of 2027.

In our experience matching providers with billing partners, the practices that handle transitions like this best are the ones whose billing company has already built the templates and payer matrices before January, rather than learning the rules from the first wave of denials. Across the billing companies in our network, a recurring pattern is that OB/GYN-focused teams treat labor-day documentation and modifier TH as standard work, while generalist billers treat them as exceptions.

OB/GYN Bill Co, powered by Billing Service Quotes, has matched more than 2,000 providers with billing partners across all 50 states. Tim Daniels, Director of Strategic Accounts at Billing Service Quotes, personally reviews each request, and many partners in the network work inside the EHR a practice already uses, including Athenahealth, Epic, AdvancedMD, Tebra, Greenway Health Intergy, drchrono, and CareCloud. The service is free to providers, because the platform is compensated by the billing companies in its network. Matched partners can also handle credentialing and contracting, which matters as practices renegotiate maternity rates against the new 2027 values.
