CMS 2026 OPPS Final Rule: What It Means for Hospital Outpatient Revenue

Overview

The Centers for Medicare & Medicaid Services (CMS) has published the Calendar Year 2026 Outpatient Prospective Payment System (OPPS) final rule, delivering a 2.9% overall payment increase — the largest update in three years.

For hospital outpatient departments, this translates to an estimated $3.2 billion in additional Medicare payments across the industry. But the devil is in the details.

Key Changes

1. Payment Rate Update: +2.9%

The 2.9% update reflects a market basket increase of 3.4% offset by a -0.5% productivity adjustment. This is a significant improvement over the 2.8% update in CY2025 and the 2.3% update in CY2024.

Revenue Impact: A mid-size hospital with $50M in annual OPPS revenue can expect approximately $1.45M in additional Medicare payments.

2. Revised Packaging Thresholds

CMS raised the packaging threshold for separately payable items from $130 to $155, meaning some items previously billed separately will now be packaged into the primary service payment.

What to watch: Review your charge master for items in the $130-$155 range. These will need updated billing workflows.

3. New Separately Payable Drug Administration Codes

Twelve drug administration codes previously packaged into clinic visit payments will now be separately payable. This is a significant win for infusion centers and oncology departments.

Affected codes include:

Chemotherapy administration codes (96401-96417)
Select biologic agent administration codes
New biosimilar administration tracking codes

4. Clinic Visit Code Adjustments

The comprehensive APC for clinic visits (C-APC 5012) sees a 3.1% increase, while lower-level clinic visits in APC 5011 increase by only 1.8%. This continues the trend of CMS steering payment toward higher-complexity outpatient encounters.
