Private payer policy updates

Dermatologists face a complex, ever-changing health care system, especially with third party payers. Use this guide to find out which insurer’s policy decisions will affect your practice.
E/M downcoding
Carriers will review claims from clinicians who are identified as coding at a higher E/M level as compared to their specialty peers. Some carriers are using proprietary algorithms that may incorrectly link specific diagnoses to certain levels of E/M, triggering claim edits within their claim processing systems. If, based on their internal claim review process, the carrier deems that the diagnosis reported does not support the E/M code level submitted on the claim, the carrier may:
Deny the claim and request resubmission of the claim with the appropriate E/M level;
Hold the claim and request documentation supporting the E/M level billed; and/or
Adjust reimbursement to reflect the lower E/M level supported by the diagnosis on the claim.
Insurers:
Aetna
Anthem
UnitedHealthcare
Tips to minimize a claim review
Make sure that the documentation supports the reported diagnosis and E/M level of service.
Include all pertinent ICD-10-CM codes to report diagnoses affecting the patient and medical complexity of the encounter.
Follow the carrier’s dispute resolution process (including submission of documentation with the appeal).
AAD resources
The AAD has a number of resources to guide dermatology practices in appropriate documentation and coding as well as effectively appeal inappropriate downcoding.

Modifier 25
E/M reduction
When an evaluation and management (E/M) code with modifier 25 and a procedure code having a 0-, 10-, or 90-day post-operative period are billed by the same clinician for the same date of service, plan will compensate the E/M service at specified percentage of the otherwise allowed amount.
Insurers:
AmBetter
Blue Cross Blue Shield of Kansas
Blue Cross Blue Shield of Rhode Island
Centene
Harvard Pilgrim Health Plan
HealthNet
Oscar
Tufts Health Plan

Global period
Payers are targeting suspected inappropriate use of modifier 25 through broad policies or targeted denials of high utilizers, post payment audit, and recoupment. When an encounter containing evaluation and management (E/M) code with modifier 25 has overlapping diagnosis as a previous encounter within a specified period of days, plan will deny reimbursement for the E/M portion of claim.
