Staying current with Medicare and Medicaid billing changes is essential for the financial health of any healthcare practice. As we move into 2026, new CMS rules, coding updates, and changes to payment models are set to impact how providers submit claims, manage reimbursements, and maintain compliance.
Whether you’re a solo practitioner, part of a group practice, or running a community health center, understanding the 2026 Medicare and Medicaid billing updates will help you avoid denials, streamline operations, and protect your revenue.
In this article, we’ll break down the most important changes, how they impact your billing processes, and what you should do now to stay ahead.
Key 2026 Medicare and Medicaid Billing Updates
1. Updated CPT and HCPCS Codes
CMS has introduced several important updates to CPT and HCPCS Level II codes for 2026, reflecting the ongoing evolution in care delivery and reimbursement.
What’s new:
- Additional codes for remote patient monitoring and chronic condition management
- Removal of outdated in-person behavioral health visit codes
- Expansion of codes for multidisciplinary care services
Action Step: Update your billing software and EHR systems to include the 2026 code set as early as Q2 to avoid rejections due to outdated codes.
2. Telehealth Billing Guidelines Expanded (With Changes)
Medicare and many state Medicaid programs will continue covering a wide range of telehealth services in 2026, but with updated policies and place-of-service (POS) code usage.
What providers need to know:
- POS codes 02 and 10 must be used appropriately to reflect where services are rendered
- Ongoing in-person visits may be required for certain behavioral health services
- Medicaid telehealth coverage will continue to vary by state and by managed care plans
Is telehealth still covered by Medicare in 2026?
Yes, Medicare continues to cover telehealth in 2026, with updated requirements around documentation and POS codes.
3. Medicare Physician Fee Schedule Updates
The 2026 Medicare Physician Fee Schedule (MPFS) includes revised conversion factors and payment rates that may affect reimbursement across common services.
Key highlights:
- Evaluation and management (E/M) visit reimbursements are adjusted based on geographic factors
- Continued emphasis on quality-of-care metrics and documentation of medical necessity
- Incentives aligned with efficiency and coordinated care
Tip: Review your top-billed codes and projected reimbursements using the updated MPFS to estimate revenue impact for the year.
4. MIPS and Quality Program Modifications
The Merit-Based Incentive Payment System (MIPS) continues to evolve. In 2026, CMS has introduced higher performance thresholds and re-weighted scoring categories.
What’s changing:
- Increased minimum performance score to avoid penalties
- Cost category weight increased to 35%
- Additional quality measures added for behavioral health, rural providers, and chronic care management
Voice Search Answer:
“What are the MIPS changes in 2026?”
MIPS 2026 includes a higher performance threshold and greater focus on cost and quality outcomes for eligible clinicians.
5. New Medicaid Prior Authorization Requirements
To streamline approvals and reduce delays, CMS is introducing a national electronic prior authorization (ePA) mandate for Medicaid providers.
What this means for providers:
- Required implementation of electronic prior authorization systems
- Faster approvals through standardized API-based communication
- Improved transparency and documentation tracking
Action Step: Work with your reliable medical billing partner or clearinghouse to ensure integration with the new ePA platforms by mid-2026.
