What is entered in box 22 of the CMS-1500 form?

Box 22 of the CMS-1500 form is designated for the entry of the claim check or payment reference number. This box is crucial for the tracking and processing of claims, as it helps insurers and medical providers reference specific claims when discussing payments or adjustments. Including the claim check or payment reference number can streamline communication between all parties involved in the claim process, allowing for quicker resolutions and clearer accountability.

Other options do not belong in box 22. Details of the patient's medical condition would typically be documented in other sections that pertain to diagnosis and services provided. The healthcare provider's signature is usually entered elsewhere on the form, often in box 31, while the patient's demographic information is found in other parts of the form designated for patient details.
