Medical billing is reshaping how practices handle coding, reimbursement, and compliance. For primary care, OB/GYN, and pediatrics, understanding these changes is essential to maintaining revenue and reducing denials. Each year, the annual update to the code system impacts how physicians document and bill services, and this year’s changes are especially significant. Keeping abreast of medical billing updates 2025 is vital for optimizing these processes.
For this reason, keeping up with medical billing updates in 2025 is crucial for all healthcare providers.
1. Medicare Physician Fee Schedule (PFS) Cuts & Conversion Factor Adjustments
The 2025 Medicare PFS final rule included a mandatory 2.83% decrease in the conversion factor (from $33.29 in 2024 to $32.35 in 2025).
This cut is required by statutory “budget neutrality” rules under MACRA and reflects the expiration of temporary payment increases from prior years.
The drop will affect most services reimbursed under the PFS—including a large portion of primary care, diagnostics, and outpatient E/M. Practices need to adjust forecasting, budgets, and possibly volumes to account for lower reimbursement. Learn more on the CMS Medicare Physician Fee Schedule.
Understanding the implications of these medical billing updates is vital for optimizing revenue cycles.
2. Primary Care Billing Updates 2025 – New Codes & Care Management
The upcoming updates will also require modifications in documentation processes.
Expansion of Advanced Primary Care Management (APCM) codes under Medicare allows practices to be compensated more holistically for managing patients with chronic or complex medical and social needs.
New billing pathways for care management, transitional care, and chronic condition oversight can help offset losses from the decreased conversion factor if practices optimize workflows. For detailed guidance, see Primary Care Coding & Billing Resources.
3. Pediatric Billing Updates 2025 – CPT, Telehealth, and E/M Revisions
The 2025 CPT code set includes 420 total updates: 270 new codes, 112 deletions, and 38 revisions. This update to the code list is one of the largest in recent years and highly relevant to pediatric practices.
Telehealth now includes new codes for both audio-video and audio-only visits for new and established patients. These are defined by either time or medical decision making.
Remote therapeutic monitoring (RTM) is more robustly covered, and vaccine administration/immunization coding has clearer documentation requirements. Learn more from the American Academy of Pediatrics Coding & Reimbursement.
4. OB/GYN Billing Updates 2025 – Telehealth, Maternity, and Postpartum Care
Telehealth in obstetrics/gynecology continues to expand, with prenatal, postpartum, and mental health services increasingly reimbursable under CMS rules.
The global maternity package (prenatal + delivery + postpartum) remains under scrutiny, with greater clarity on which services are included versus which should be billed separately.
Postpartum care is shifting as Medicaid state plan amendments extend coverage for pregnant patients to one year postpartum. After about 12 weeks, practitioners should use E/M or other appropriate procedure codes instead of assuming global maternity codes cover all care. For more info, see ACOG Coding & Billing Updates.
In conclusion, adapting to these updates is essential for maintaining compliance.
5. ICD-10-CM Billing Updates 2025 & Documentation Compliance
ICD-10-CM changes effective October 1, 2024 include 252 additions, 13 deletions, and 36 revisions. Practices should confirm that their EHR and coding software are fully updated.
New compliance expectations emphasize documentation of social determinants of health, medical decision making (MDM), and telehealth/virtual visits. For telehealth, documentation must include patient consent, the platform used, and time spent. See the CDC ICD-10-CM 2025 Updates for official guidance.
6. Practical Impacts & Next Steps
Audit payer contracts and reimbursement rates. With the average pay cut, practices with higher Medicare reliance will feel more pressure—renegotiating with commercial payers can help.
Update billing and EHR systems. Ensure new CPT and ICD-10 codes are loaded, APCM/care management codes are active, and templates support documentation requirements.
Train staff, coders, and clinicians on new rules, including telehealth coding, maternity global packages, and postpartum care.
Track denials and rejections closely. Telehealth, remote monitoring, and postpartum visits are at higher risk for denials due to documentation mismatches.
Consider alternative payment models like APCM, ACOs, and value-based care to align with 2025 billing structures. Learn more about revenue cycle best practices at HFMA Revenue Cycle Resources.
Key Takeaways: Medical Billing Updates 2025
- Medicare conversion factor decreased by 2.83%, impacting reimbursement across most services.
- New APCM codes give primary care practices expanded billing opportunities.
- Pediatrics sees major CPT updates, especially for telehealth and remote monitoring.
- OB/GYN billing rules for global maternity packages and postpartum care are being clarified.
- ICD-10-CM updates require updated EHRs and stricter documentation compliance.
Conclusion
While the Medicare conversion factor cut is a concern, practices can leverage new codes, telehealth reimbursement, and advanced care management to remain financially strong. Providers should also be prepared for a surprise in January, when payer-specific interpretations of these codes may affect reimbursement.
