The bill directs the HHS Inspector General to conduct a comprehensive study of how CMS adds, modifies, and removes Medicare billing codes under Title XVIII. The study will examine the data the agency uses, how it analyzes that data, and trends in code changes, including which medical specialties are expanding code usage and how code changes influence costs and outcomes.
Not later than 12 months after enactment, the Inspector General must report to Congress with findings and recommendations to improve transparency and oversight. The bill also requires annual reporting by the Secretary of Health and Human Services beginning in 2025, listing new billing codes added in the preceding year along with the associated volume and expenditures, with this information publicly available on the CMS website.
At a Glance
What It Does
The bill tasks the HHS OIG with a comprehensive study of CMS processes for adding, modifying, and removing Medicare billing codes, and requires a report to Congress within 12 months. It also mandates an annual public listing of newly added codes, with volume and expenditure data.
Who It Affects
CMS and its contractors responsible for code governance; healthcare providers and billers who work with Medicare claims; and Congressional overseers who rely on transparent data.
Why It Matters
The transparency and baseline data created by the study and annual reports give policymakers and providers clearer visibility into how coding changes affect costs and care delivery.

What This Bill Actually Does
The Oversight of Medicare Billing Code Cost Act seeks to illuminate how Medicare codes are created and adjusted. It designates the HHS Office of Inspector General to perform a comprehensive study of CMS processes for adding, modifying, and removing billing codes under title XVIII, with a focus on the data used, analytical methods, and trends in changes across codes.
The study will also look at how code changes affect costs, utilization, and patient outcomes, and it will identify growth areas by specialty. The IG must deliver a report to Congress within 12 months containing findings and recommendations to improve transparency and oversight.
Separately, the bill requires the Secretary of Health and Human Services to publish an annual list of all new codes added in the prior year, including the volume of use and the expenditures associated with those codes. This information must be publicly accessible on the CMS website beginning in 2025.
Taken together, the measure creates a formal data trail around Medicare coding activity intended to support accountability, budgeting, and policy evaluation. The transparency obligation is designed to help clinicians, coders, payers, and policymakers understand how coding changes translate into real-world costs and care patterns.
The Five Things You Need to Know
The bill requires the HHS OIG to conduct a comprehensive study of CMS processes for adding, modifying, and removing Medicare billing codes, with a defined scope.
The IG study must cover data types used, analysis methods, growth trends, and monitoring of outcomes and costs.
A report from the IG to Congress is due within 12 months after enactment, including recommendations for legislative and administrative actions.
Starting in 2025, CMS must annually publish a list of codes added in the prior year, plus their volume and expenditures.
The public codes publication must be accessible on the CMS website, and the legislation envisions follow-on actions based on the IG's findings.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
OIG study of CMS code processes
This subsection directs the Inspector General of the Department of Health and Human Services to conduct a comprehensive study of how CMS adds, modifies, and removes Medicare billing codes under Title XVIII. The study will assess the data CMS uses, the analytical methods employed, trends in code changes across time, and which specialties drive growth. It will also examine how CMS monitors the downstream effects of coding changes on outcomes and costs, providing a governance-focused view of the code-management process.
IG report to Congress
Not later than 12 months after enactment, the Inspector General must submit to Congress a report detailing the study’s findings and offering recommendations for legislative and administrative actions to improve transparency and oversight of Medicare billing codes. This delivers a formal, data-backed basis for potential policy adjustments.
Annual public reporting on new codes
Beginning in 2025, the Secretary of Health and Human Services must annually publish a public report listing any billing codes added in the preceding year under title XVIII, along with the associated volume and expenditures. This information must be made publicly available on the CMS website, creating a rolling, accessible dataset that supports accountability and policy analysis.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Congressional oversight committees receive clearer data to monitor Medicare coding practice and costs.
- HHS Office of Inspector General gains a defined mandate and data to inform audits and evaluations.
- CMS program integrity and data analytics teams obtain a structured framework for governance and transparency.
- Medicare providers and coding staff benefit from clearer visibility into code changes and their financial impacts.
- Medicare beneficiaries may experience more predictable reimbursements and care planning through clearer coding practices.
Who Bears the Cost
- CMS and its contractors must allocate resources to data collection, code-tracking, and public reporting.
- HHS OIG staff and contractors will need resources to perform the study and prepare the report.
- Potential downstream costs for providers if policy changes are recommended or enacted as a result of the IG’s findings.
- Congress may incur administrative costs to conduct hearings or oversight based on the IG’s recommendations.
Key Issues
The Core Tension
The central tension is between increasing transparency in Medicare billing code governance and the administrative burden and potential disclosure risks that come with detailed, publicly accessible coding data. On one hand, better data supports accountability and informed policymaking; on the other hand, CMS will need to balance data quality, privacy, and operational feasibility while scaling up annual reporting.
The bill creates a formal framework for transparency around Medicare billing codes, but it also imposes new data collection and reporting requirements on CMS and the OIG. The added transparency could improve accountability and inform future policy, yet it raises questions about data quality, standardization across specialties, and the burden of sustained data publication.
There are no explicit penalties tied to noncompliance, and the bill does not specify funding levels for the new duties, which could affect implementation. A prudent reader will watch for how CMS handles data definitions, publication cadence, and any unintended consequences of publicizing granular coding activity.
