Which of the following is an example of a billing and coding error that may cause revenue fluctuations?

Incorrect patient demographic information is a critical aspect of billing and coding that can lead to significant revenue fluctuations. This type of error may result in denied claims or delayed payments because the billing system relies on accurate patient information to process claims effectively. When demographic details such as the patient's name, insurance information, or policy numbers are incorrect or missing, it creates obstacles in the claims submission process.

Health insurance providers need to verify the identity of the patient and their coverage before processing any claims. If there are discrepancies in the demographic information provided, claims can be denied, leading to revenue loss for the practice. This situation not only affects immediate cash flow but can also result in long-term financial implications as the practice spends additional resources on correcting errors and resubmitting claims.

Other factors mentioned, like patient attendance, hospital stay duration, and staffing levels, can impact the overall operations and efficiency of a practice but are not directly tied to the coding and billing accuracy needed for revenue recognition. These operational aspects do not directly relate to the submission of claims and the reimbursement process in the same critical way as incorrect demographic data does.
