Medical Claim Denial Rates in 2026: Are Denials Rising?

Medical claim denials remain one of the most persistent revenue-cycle challenges for healthcare providers in 2026. Recent industry research suggests that the pressure is increasing for a meaningful share of providers, although there is no single denial rate that applies to every specialty, payer, claim type, or organization.

What Is a Medical Claim Denial?#

A medical claim denial occurs when a payer determines that a submitted claim will not be paid as billed. A claim may be denied because of eligibility problems, missing authorization, coding issues, insufficient documentation, medical-necessity requirements, duplicate billing, or other payer-specific rules.

Denials are different from simple claim rejections. A rejection generally occurs before a claim enters the payer's adjudication process, while a denial usually follows payer review.

Are Claim Denial Rates Rising in 2026?#

The available 2026 data indicates that denial pressure is significant and has increased for some provider organizations.

A 2026 Guidehouse and HFMA survey found that the share of providers reporting final denial rates above 5% nearly doubled to 20%, compared with 12% in the previous survey. The same research found that 88% of respondents ranked payer challenges among their top three revenue-cycle concerns. citeturn0search0

Experian Health also reported in July 2026 that 25% of providers surveyed had experienced increased denial rates over the previous 12 months, while more than four in ten reported that at least 10% of their claims were denied. citeturn0search3

These figures should not be interpreted as a universal 2026 denial rate for all U.S. healthcare providers. Survey populations, definitions, specialties, payer mixes, and claim types differ.

Why Are Denials Becoming a Bigger Revenue-Cycle Problem?#

Several operational pressures are contributing to the problem.

1. Front-End Errors#

Errors made before a claim is submitted can follow the claim through the entire revenue cycle. Patient registration, eligibility verification, insurance information, and authorization workflows are especially important.

A 2026 survey reported that insurance eligibility and benefits verification, prior authorization, and patient registration errors were among the leading drivers of claim denials. citeturn0search2

2. Prior Authorization Problems#

A service may require prior authorization before treatment is provided. If authorization is missing, expired, incomplete, or inconsistent with the service ultimately billed, payment can be delayed or denied.

3. Coding and Claim-Data Errors#

Incorrect CPT or HCPCS codes, diagnosis-code mismatches, modifiers, demographic errors, and other claim-data problems can create avoidable payment issues.

4. Payer-Specific Requirements#

Payers may apply different policies, documentation requirements, authorization rules, and claim-editing logic. A workflow that works for one payer may not work for another.

5. Delayed Denial Follow-Up#

A denial that is not reviewed and worked quickly can become an aging A/R problem. The longer an account remains unresolved, the greater the operational effort required to recover the revenue.

Denial Rates Vary by Payer and Provider#

There is no single "normal" denial rate for every healthcare organization.

A 2026 peer-reviewed analysis using a large multipayer claims dataset found substantial differences in initial denial rates by payer and service type. For example, the study reported initial denial rates of 15.1% for professional claims under Medicaid managed care and 20.0% for inpatient claims under Medicare Advantage in the dataset studied. citeturn0search1

The study examined claims from 2019, so these figures should be treated as evidence of variation rather than as a 2026 industry benchmark.

For Medicare fee-for-service, MedPAC reported that 2024 initial-denial rates were 8% for Part A claims, 10% for Part B claims, and 14% for DMEPOS claims. citeturn0search9

What Should Practices Track in 2026?#

Instead of looking only at a single denial percentage, practices should monitor the complete denial picture.

Useful metrics include:

• Initial denial rate
• Final denial rate
• First-pass acceptance rate
• Top denial reason codes
• Denials by payer
• Denials by CPT/HCPCS code
• Denials by provider
• Denials by location
• Authorization-related denials
• Eligibility-related denials
• Coding-related denials
• Average days to resolve a denial
• Appeal success rate
• Dollars tied up in denied claims
• A/R aging associated with denials

CMS explains that claim and review denial reason codes help providers understand why a claim was denied and what information is associated with the decision. citeturn0search7

How Can Providers Reduce Denials?#

A practical denial-prevention strategy starts before the claim reaches the payer.

Front-End Controls#

Verify:

• Patient demographics
• Insurance eligibility
• Benefits
• Authorization requirements
• Referral requirements
• Coverage dates
• Provider participation

Clean Claim Controls#

Before submission, review:

• Patient and payer information
• CPT/HCPCS codes
• Diagnosis codes
• Modifiers
• Units
• Place of service
• Authorization information
• Required documentation

Denial Management#

For denied claims:

1. Categorize the denial.
2. Identify the root cause.
3. Correct the issue where appropriate.
4. Submit a corrected claim or appeal.
5. Track payer response.
6. Measure the result.
7. Feed recurring issues back into the front-end workflow.

The Bottom Line#

The 2026 evidence points to continued and, for some providers, increasing denial pressure. However, a single nationwide denial-rate number can be misleading because denial rates vary significantly by payer, provider type, service, and methodology.

The most useful approach is to identify where denials are occurring, why they are occurring, how much revenue is affected, and whether the same errors are repeating.

A structured revenue-cycle review can help practices find preventable leakage before denied claims become aging A/R.
