Final answer:
The leading reason a claim is denied is incorrect patient information, which can be prevented by collecting accurate intake information every time.
Step-by-step explanation:
The correct answer is Incorrect patient information. This is one of the leading reasons a claim is denied and can be prevented by collecting accurate intake information every time. When a claim is submitted with incorrect patient information, it can lead to confusion and errors in the processing of the claim. For example, if the patient's name or date of birth is entered incorrectly, it may result in the claim being rejected. By ensuring that accurate intake information is collected for every patient, healthcare providers can help prevent these types of denials and ensure that claims are processed smoothly.
