Key Takeaways

The global maternity package is ending. Beginning January 1, 2027, OB care will be coded and reimbursed across four distinct phases: antepartum, labor management, delivery and postpartum.
This is more than a coding change. The transition will impact documentation, workflows, EHRs, payer contracts, provider billing practices and overall revenue cycle performance.
E/M coding becomes critical. Antepartum and postpartum services will shift to evaluation and management (E/M) coding, making accurate documentation and coding expertise essential.
Waiting creates financial risk. Organizations that delay preparation could face increased denials, audit exposure, reimbursement challenges and lost revenue.
Education is the best defense. Targeted training for providers, coders and revenue cycle teams can help organizations build readiness and protect revenue before the 2027 go-live date.

The Biggest OB Coding Shift in 30 Years Hits January 1, 2027. Your Revenue Cycle Isn’t Just a Coding Problem.

On January 1, 2027, the global maternity package goes away. In its place, the American Medical Association’s (AMA’s) CPT Editorial Panel has approved a full restructuring of maternity care services that separates obstetric (OB) care into four distinct phases: antepartum, labor management, delivery and postpartum. Seventeen legacy codes will be deleted, twelve new codes will be added and six existing codes will be revised, replacing a bundled model that has been in place since the 1990s.

This isn’t a routine update. It’s a reset of how OB care is documented, coded and reimbursed. And it’ll touch every part of your revenue cycle, not just the coding team.

If you lead a hospital, health system, ambulatory group or physician practice with OB services, the question isn’t whether to prepare. It’s how fast you can build the operational readiness before Q1 2027 denials start hitting your work queues.

What’s Actually Changing

For more than three decades, most OB care has been reimbursed under a single global code that bundles nine months of care into one payment. That model no longer reflects how care is delivered.

Beginning January 1, 2027, maternity care will be reported at the service level across four separate phases, a change the American College of Obstetricians and Gynecologists (ACOG) says has been long overdue.

Antepartum Care
All current antepartum codes are deleted. Prenatal visits shift to standard evaluation and management (E/M) coding on a per-encounter basis.
Labor Management
This new coding and documentation concept has daily reporting with separate codes for initial and subsequent days based on service complexity with distinct delivery-care rules
Delivery
Delivery is coded separately from labor, with streamlined codes for vaginal, vaginal birth after cesarean (VBAC and cesarean deliveries, plus new codes for third- and fourth-degree laceration repair and hysterectomy following cesarean.
Postpartum care
All current postpartum codes are deleted and reported per encounter using E/M codes and several existing CPT codes usually performed postpartum are moved into this new section. This includes a new code for uterine tamponade by balloon, catheter, vacuum or packing material.

The AMA has released the codes ahead of the standard publication schedule to give physicians, payers, coders and electronic health record (EHR) vendors more time to prepare.

Why This Is a Revenue Cycle Problem, Not Just a Coding Problem

If your teams are treating this as a coding refresh, they’re already behind. The scope of change touches documentation, workflows, EHR templates, payer contracts and provider classification. Every one of those levers directly affects reimbursement.

The RVS Update Committee (RUC) who evaluates CPT codes and assigns physician work RVUs recommended a value structure to be budget neutral in aggregate, but budget neutral at the system level doesn’t translate to neutral impact for individual practices. Revenue will get redistributed based on how care is delivered, how often patients are seen and how well your organization adapts. Some practices will capture more. Others will lose ground.

Add to that the pressure your teams are already under. Hospitals lost more than $48 billion in earned revenue to denials and uncollected patient balances in 2025, a 25% jump in a single year, according to Kodiak Solutions. The 2025 MDaudit Benchmark Report shows outpatient coding–related denials increased another 26% on top of a 126% surge the prior year. The gap between what’s coded and what’s paid keeps widening. A structural change of this size will only accelerate that trend for organizations that aren’t prepared.

E/M and Documentation Mastery Is the Hidden Curriculum

Here’s the piece most organizations are underestimating. Antepartum and postpartum care now run on E/M rules. That means accurate coding depends on documentation precision, data and risk scoring and true E/M leveling in an OB workflow.

Pregnancy contributes to moderate complexity but doesn’t guarantee an E/M level on its own. OB templates weren’t built for E/M capture. Providers haven’t been trained to document for E/M complexity. And many coders don’t have recent E/M experience in OB settings. New labor management and delivery-care codes also require more detailed documentation to support service complexity, daily reporting and delivery-related services.

That capability gap is showing up across the workforce. AAPC estimates a 12% nationwide coding talent gap in 2025, layered on top of a 30% shortage of certified medical coders, with wage stagnation and burnout driving turnover. The teams you have left are the teams who’ll carry this transition. Their skill depth is your revenue insurance policy.

What Happens If You Wait

The organizations that wait until Q1 2027 will pay for it twice: once in denials, once in audits.

Documentation gaps cascade into denials, resubmissions and delayed cash. Industry-wide initial claim denial rates are already sitting near 11.8% heading into the transition.
Undercoding due to understated documentation leads directly to revenue loss.
Overcoding increases audit exposure at a time when payer scrutiny is climbing, with total at-risk audit amounts up 30% year over year.
Provider structure confusion creates missed revenue opportunities where multiple providers can bill or multiple services can be captured on the same day but aren’t.

The US is already grappling with a maternity care crisis, with more than 1,700 hospitals reporting quality and services data on OB services through Leapfrog, as scrutiny of maternal outcomes and care access continues to rise. A financial disruption on top of an already stressed OB service line will be felt system-wide.

Proactive Education Is the Only Defense That Actually Works

Reactive training doesn’t scale. By the time your team feels the pain, denials are already stacked in a work queue and the cash is already delayed. What OB and revenue cycle teams need now is a structured path to build the operational readiness before the go-live date. That means:

Provider education focused on documentation for each phase of care in OB workflows
Coder retraining with a modern E/M refresh
OB template redesign and workflow updates
Payer contract alignment and clear provider classification
Ongoing reinforcement so knowledge sticks after the initial rollout

That’s not a webinar. That’s a learning strategy.

FAQs

What is changing with maternity coding on January 1, 2027?
The global maternity package is being eliminated. OB care will be reported across four separate phases: antepartum, labor management, delivery and postpartum. The AMA CPT Editorial Panel has approved 17 code deletions, 12 new codes and 6 revisions, with antepartum and postpartum care shifting to standard E/M coding.

Who is affected by the 2027 CPT maternity code changes?
Any hospital, health system, ambulatory practice, physician group or payer touching OB services is affected. That includes coders, billers, revenue cycle leaders, OB/GYN providers, EHR vendors and finance leaders responsible for reimbursement outcomes.

Why is E/M coding suddenly central to OB workflows?
Antepartum and postpartum visits now use E/M rules for reporting. Accurate leveling depends on documentation precision, data and risk scoring. OB templates and provider workflows weren’t built for E/M capture, so most teams need retraining and template redesign to code accurately.

What is the revenue risk if we don’t prepare?
Undercoding leads to revenue loss. Overcoding increases audit exposure. Documentation gaps drive denials. Provider classification errors create missed billing opportunities. Organizations that wait until the change is in force will absorb Q1 2027 denials and delayed cash on top of an already pressured revenue cycle.
