Incorrect coding is one of the most frequent billing errors in gynecology. Using the wrong [ICD-10](https://) or [CPT codes](https://) can lead to claim denials, delayed payments, or reduced reimbursement. For instance, if a procedure is coded incorrectly, insurance companies may reject the claim, considering it medically unnecessary or non-covered. This not only affects the financial health of the practice but also frustrates patients who may then be held responsible for higher out-of-pocket costs.
