What is documented in box 14 of the CMS-1500 form?

Box 14 of the CMS-1500 form is specifically designated for documenting the date of the patient's first visit related to the claim. This information is crucial as it helps insurance companies understand the timeline of care. Establishing the initial visit date provides context for the medical services billed on the claim, allowing the insurance provider to determine coverage eligibility and the sequence of treatment. It is particularly important when evaluating the necessity and appropriateness of services rendered, especially in ongoing treatment scenarios.

The first visit date can also assist in identifying any pre-existing conditions or the start of a new episode of care, impacting how claims are processed and what benefit limitations may apply. Correctly filling out this box can facilitate smoother communication and processing between healthcare providers and insurance payers, ultimately supporting better patient care outcomes.
