AMA Obstetric Coding Changes 2027: Revenue Impact Across Practices, Health Systems, and EMR Platforms

A strategic analysis of how the shift from global OB packages to encounter-based coding will reshape revenue, workflows, and financial performance across healthcare organizations

Introduction

The upcoming AMA obstetric coding changes in 2027 represent a major structural shift in how OB-GYN care will be reimbursed across the healthcare ecosystem.

The transition from the traditional global OB package to a fully encounter-based, unbundled model will impact not only private practices, but also health systems, multi-location groups, and EMR platforms that support revenue cycle workflows.

At a high level, this change is being positioned as an improvement that aligns reimbursement more closely with clinical work.

However, the financial and operational implications are more nuanced.

This is not just a coding update. It is a system-wide shift in how revenue is generated, captured, and distributed.

What are the AMA Obstetric Coding Changes in 2027?

Under the new model:

• Prenatal care will be billed using E/M (Evaluation & Management) codes
• Delivery services will be billed separately
• Postpartum care will become separately billable
• Ancillary services will be formally recognized

This eliminates the bundled structure of the global OB package and introduces a visit-based reimbursement model.

Why This Matters Across the Healthcare Ecosystem

This change does not affect a single segment of healthcare. It impacts:

• Private practices: revenue predictability and workflow structure
• Health systems: standardization, scale, and financial modeling
• Multi-location groups: consistency across providers and sites
• EMR and health tech platforms: documentation workflows, coding logic, and revenue capture systems

Benefits of the New OB-GYN Coding Model

There are clear advantages to this shift. For the first time, reimbursement begins to reflect the full scope of OB-GYN care, including:

• Extended postpartum care (up to 12 weeks)
• Counseling and care coordination
• Mental health services
• High-risk pregnancy complexity

Historically, these areas were underrepresented in bundled reimbursement models. This creates an opportunity for more accurate and transparent revenue capture.

The Hidden Revenue Challenge

Despite these benefits, a critical nuance is often overlooked. Under the current system, clinicians frequently manage multiple issues within a single visit:

• A routine OB encounter
• Plus a separate medical condition

These could be billed as:

• Global OB component
• + separate E/M service

Real-world impact: $150 to $200+ per encounter

Financial Impact of OB Coding Changes on Healthcare Organizations

With the transition to encounter-based billing, these combined services are expected to be captured under a single E/M framework.

Typical Medicare reimbursement:

• 99213: approximately $90
• 99214: approximately $125

This means: That same encounter may now generate ~$125

Potential Revenue Gap
Across certain workflows and care models, this creates: A $25 to $100 revenue gap per encounter. At scale, this has implications not just for individual practices but for entire health systems.

Can Revenue Be Maintained or Improved?
Yes…..but it depends on how the system is managed. The new model introduces opportunities to offset or exceed potential losses through:

• Additional billable postpartum visits
• Increased patient touchpoints
• Better capture of preventive and counseling services
• More consistent use of higher-level E/M codes for complex care

Across the full episode of care: Revenue may remain stable or improve if workflows are optimized

The Real Shift: From Bundled to Performance-Driven Revenue

This is the most important takeaway. Healthcare organizations are moving from:
Bundled, predictable revenue models
To:
Performance-driven revenue systems

What Will Determine Revenue Performance Now?

Under the new model, financial outcomes will depend on:

• Documentation accuracy and completeness
• E/M coding precision and leveling
• Clinical workflow design and visit structuring
• Revenue cycle execution and consistency
• Payer-specific policies and behavior

Implications for EMR and Healthcare Technology Platforms

For EMR and digital health platforms, this shift is equally significant. Systems must now support:

• More granular documentation workflows
• Accurate E/M leveling guidance
• Integrated coding support
• Visibility into revenue performance metrics

Platforms that fail to adapt risk:

• undercoding
• inconsistent revenue capture
• reduced financial performance for their users

Final Analysis: Redistribution of Revenue

The 2027 AMA obstetric coding changes will not affect all organizations equally.

• Some will experience margin compression
• Others will capture new revenue opportunities

This isn’t a uniform change. It is a redistribution of revenue based on operational and financial maturity.

Should Organizations Prepare Now?

Yes. Organizations that:

• model financial impact
• align clinical and revenue workflows
• optimize documentation and coding

will be significantly better positioned than those that wait to react.

Frequently Asked Questions

What is changing in OB-GYN coding in 2027?
The global OB package is being replaced with an encounter-based model where prenatal, delivery, and postpartum care are billed separately.

How will this impact hospitals and health systems?
It will affect revenue predictability, workflow standardization, and financial modeling across OB-GYN departments.

What does this mean for EMR systems?
EMRs must adapt to support E/M-based documentation, coding accuracy, and improved revenue visibility.

Will revenue decrease under the new model?
In some workflows, yes. However, optimized systems may offset or exceed losses through improved revenue capture.

Final Thought

Revenue will no longer be predictable by structure. It will be determined by how effectively your system performs.
