The 2026 Hospital Billing Compliance Checklist (CMS + No Surprises Act Updates)

In 2026, hospital billing compliance is more than just a back-office concern — it’s a financial and reputational imperative.

With ongoing updates from CMS (Centers for Medicare & Medicaid Services), enforcement of the No Surprises Act, and evolving payer expectations, hospital leaders must be proactive to avoid audits, reduce denials, and ensure ethical billing practices.

What Is Hospital Billing Compliance?

Hospital billing compliance refers to the hospital’s ability to adhere to:

• Federal and state regulations (CMS, OIG, HHS)
• Payer contract rules
• Patient protection laws (e.g. No Surprises Act)
• Internal audit and revenue cycle integrity

Non-compliance can lead to civil monetary penalties, payer clawbacks, reputational damage, and criminal charges in cases of fraud.The 2026 Hospital Billing Compliance Checklist

Each of the items below is backed by active regulatory guidance and enforcement updates for 2026.

 1. Verify Compliance With 2026 CMS Coding Updates

CMS releases annual updates to CPT, HCPCS, and ICD-10-CM codes. Incorrect use of these codes is one of the top causes of claim denials and compliance violations.

Checklist:

• CPT/HCPCS/ICD-10 updates implemented in EHR and billing systems
• Coding teams trained on new 2026 rules
• NCCI edits reviewed and scrubbers updated

2. Ensure No Surprises Act Enforcement Compliance

As of 2026, HHS, CMS, and the Department of Labor continue active enforcement of the No Surprises Act. Hospitals must meet requirements for:

• Good Faith Estimates
• Balance billing protections
• Out-of-network dispute resolution

Checklist:

• Front desk and revenue staff trained on NSA rules
• Systems capture & deliver Good Faith Estimates
• Compliance plan in place for OON services
• Arbitration data tracking process documented

 3. Perform Internal Billing & Coding Audits

Internal audits are critical to identify incorrect billing patterns before external payers or auditors do.

Reference: OIG Compliance Program Guidance

Checklist:

• Quarterly audits of high-risk service lines (e.g., ED, imaging, anesthesia)
• Random claim sampling across all departments
• Documentation supports billed services
• Denials reviewed for potential compliance trends

 4. Update Payer Contract Compliance and Fee Schedules

Hospitals must align their billing practices with payer-specific terms, especially regarding reimbursement rates, prior authorizations, and documentation requirements.

Checklist:

• Fee schedules updated per payer contract
• Contractual obligations reviewed annually
• Prior authorization workflows updated
• EOBs reconciled against contract terms

 5. Validate Provider Credentialing and NPI Accuracy

Incorrect NPI or missing credentialing information is a leading cause of claim rejection and payment delay.

Checklist:

• All billing and rendering NPIs verified
• Credentialing files up to date with each payer
• Provider taxonomy codes mapped correctly
• Cross-checks between credentialing and billing teams

 6. Monitor the OIG Exclusion List Regularly

Billing for services rendered by individuals or entities on the OIG Exclusion List can result in serious penalties.

Checklist:

• Monthly review of OIG Exclusion List
• HR and billing departments coordinated
• Written policy for exclusion monitoring

7. Implement Patient-Friendly Billing Practices

Hospitals are expected to offer transparent and ethical billing in line with CMS Hospital Price Transparency Final Rule.

Checklist:

• Standard charge file published on website
• Estimates available upon request
• Itemized bills provided in plain language
• Support system for patient billing disputes

• Non-compliance can trigger Medicare audits, private payer clawbacks, or even federal investigations.
