Final answer:
The best way to resolve claim processing errors according to Cigna is to submit a corrected claim, which addresses issues and expedites the review process.
Step-by-step explanation:
According to Cigna, the best way to resolve claim processing errors is to submit a corrected claim. This action directly addresses any issues with the initial claim submission such as incorrect patient information, billing codes, or provider details. By correcting and resubmitting the claim, healthcare providers can expedite the review process and obtain resolution. In the event that the corrected claim does not resolve the issue, providers may then consider other options such as filing an appeal or contacting Cigna Healthcare for assistance.
