Radiology practices process a large volume of claims, have complex coding systems, and payers enforce significant rules regarding claims processing. In 2026, the amount of time it takes for imaging services to process and get paid for claims is increasing as a result of delays and denials. Even minor gaps in follow-up or documentation create problems with cash flow.
As a result, strong radiology accounts receivable management is now critical to ensure steady revenue flow. Optimizing AR and denial workflows helps practices reduce days in AR, increase recovery rates, and protect margins— particularly as reimbursement updates in the 2026 CMS Physician Fee Schedule place added emphasis on clinical justification and coding accuracy.
Radiology AR Pressure in 2026
Imaging services are subject to greater payer scrutiny due to cost and utilization trends. The growth of prior authorizations, medical necessity reviews, and post-payment audits has caused an increase in the denial of payments for these services. Below are some key factors creating these roadblocks to payment:
- medical necessity denials
- delayed payments caused by authorization requirement issues
- coding-related errors and modifier errors
- slow payer responses for unpaid claims
The lack of structure causes AR backlogs to rapidly increase.
Act Early on Accounts Receivable Follow-Ups
Timing matters. The longer a claim takes to resolve, the harder it is to collect the funds on that claim. Effective follow‑up is essential, especially with the growing complexity of radiology billing workflows. Best practices are:
- Follow up according to the timelines established by the payers.
- Log every contact made with payers.
- Escalate stalled claims as soon as possible.
- Do not rely solely on automated status tools to check claim status.
Early follow-up increases the chance of recovering money owed.
Create a Process for Identification of Denial Root Causes
A significant portion of denials occurring in radiology is because we aren’t fixing what caused the denial in the first place. Some of the common reasons for denials are:
- Missing or inadequate clinical documentation
- Incorrect modifiers
- Discrepancy between the authorization and the order intake
- Disagreement on medical necessity
Improve Your Documentation Prior to Billing
Failure to bill due to missing diagnostic elements, such as incomplete radiology reports, is common. To reduce risk:
- clinical indications must be clearly documented
- findings must match diagnosis codes
- medical necessity must be explicitly stated
- high-risk imaging studies should be reviewed before submission
Cleaner claims are reimbursed faster.
Consistency in the Denial Appeal Process
There is no consistency between denial appeal processes. By having a consistent approach to the appeal process, there will be an increased chance of overturning denials. The appeal process should include:
- Templates to appeal the most common reasons for denial
- Payer-specific references to specialty policies
- Defined timelines for submitting appeals
- Visibility of the status of appeals
The increased success of standardization will increase the success rate of all appeals.
External Support in Managing AR
Many practices struggle to manage AR internally. As a result, many outsource accounts receivable management services and denial management services to firms like RCM Workshop to improve consistency and performance. Services provided include:
- dedicated follow-up teams for accounts receivable
- expert radiology-specific denial management services
- consistent documentation, reporting, and analysis
- reduced administrative burden on internal staff
Effective AR segmentation, timely follow-up, improved documentation, and root-cause analysis of denials are essential for speeding collections and reducing write-offs. Strong AR and denial management will remain critical to radiology practice success through 2026.
