Final answer:
When appealing to Cigna for timely filing, the patient's complete medical chart is not typically required. Instead, the focus should be on providing an original EOB, a filled out appeal form, and justification for reversing the decision based on timely filing issues.
Step-by-step explanation:
When submitting an appeal for timely filing to Cigna, the following items are typically required: an original Explanation of Benefits (EOB), a completed appeal form, and documentation to justify the reversal of the decision. However, the patient's complete medical chart is not typically required for a timely filing appeal, as this level of detail is often not necessary to address filing date issues. It is important to focus on providing Cigna with clear evidence and a rationale as to why the claim was not filed in a timely manner and why an exception should be granted.
