Final answer:
Claims with invalid or missing diagnosis codes will be rejected, and this can result in delays in payment. Correct coding is essential for timely processing and avoiding claim rejections.
Step-by-step explanation:
Claims that have invalid or missing diagnosis codes will most likely be rejected. In the medical billing process, accurate and complete diagnosis codes are essential for insurance companies to process claims. If these codes are incorrect, incomplete, or missing, the claim cannot be processed correctly, which typically results in a rejection. Once rejected, the claim often needs to be corrected and resubmitted, which can lead to delays in payment. Medical professionals and billing specialists must ensure that all claims are correctly coded to avoid claim rejections and to ensure timely payments for services rendered.
