Quick Explanation
This denial occurs when an imaging procedure intended for routine preventive screening is billed using diagnostic procedure codes, or when screening diagnosis codes are incorrectly paired with diagnostic CPT codes. Payers strictly distinguish between preventive screenings (which are typically covered at 100% under the ACA) and diagnostic imaging performed to evaluate active signs, symptoms, or past abnormal findings.
Common Causes for R30
Denials with code R30 typically happen for the following specific reasons:
- Billing a diagnostic mammography CPT code (77065 or 77066) for a routine, asymptomatic patient who should have received a screening mammography code (77067).
- Pairing a screening encounter ICD-10-CM code (such as Z12.31) as the primary diagnosis on a diagnostic imaging procedure code.
- Failing to append Modifier GG when a screening mammogram detects an abnormality and is converted to a diagnostic mammogram on the same day.
- Using order forms or electronic health record templates that do not clearly differentiate between screening and diagnostic clinical pathways, leading to incorrect code selection.
How to Prevent R30 Denials
To avoid receiving this denial in the future, implement these specific checks:
- Implement automated claim scrubbing rules to flags mismatches between screening CPT/HCPCS codes and diagnostic ICD-10-CM codes before submission.
- Educate clinical and coding staff on CMS guidelines regarding the transition from screening to diagnostic services, particularly the application of Modifier GG.
- Verify the ordering clinician's documentation to ensure the patient's clinical history (symptomatic vs. asymptomatic) matches the selected imaging modality.
- Update EHR templates to prompt providers for specific clinical indicators when ordering diagnostic imaging to prevent accidental screening mischaracterization.

Denial Code: R30 - Screening imaging coded as diagnostic
Dear Appeals Department,
I am writing to appeal the denial of the above-referenced claim, which was denied with code R30: "Screening imaging coded as diagnostic".
We are appealing the denial for the imaging service rendered, as the documentation supports that the procedure performed was a routine preventive screening in accordance with AMA CPT and CMS guidelines. The medical record confirms the patient was completely asymptomatic and met all clinical criteria for a preventive screening, which is fully covered under the Affordable Care Act (ACA) preventive service mandates. There were no signs, symptoms, or previous abnormal findings documented that would clinically justify a diagnostic study. We request that the claim be reprocessed and paid under the patient's preventive care benefits using the screening guidelines.
Attached please find:
1. A copy of the original claim.
2. The relevant medical records supporting the service.
3. [Any other supporting documents].
We respectfully request that you reprocess this claim for payment.
Sincerely,
[Your Name]
