Quick answer

Duplicate medical charges occur when the same service is billed more than once. Request an itemized bill, check for identical CPT codes or charges, and dispute duplicates in writing with the provider.

How To Spot Duplicate Charges

Request an itemized bill and look for identical CPT codes appearing more than once. Also check for the same service listed under different descriptions or on different dates when only one visit occurred.

Common Types of Duplicate Charges

Duplicates can appear as: two charges for the same lab test on the same date, the same imaging study billed twice, duplicate facility fees, or the same medication administered once but charged twice.

How To Dispute

Contact the billing department, identify the specific duplicate charges, and request removal. Reference the itemized bill and your EOB. Put your dispute in writing and keep copies.
