Final answer:
When informed of a mistake in documenting a patient's health insurance information, acknowledge the concern, review the documentation, make corrections, and inform the appropriate parties.
Step-by-step explanation:
If a colleague tells you that you have documented a patient's health insurance information incorrectly, it is important to handle the situation professionally and take appropriate action. First, acknowledge your colleague's concern and express gratitude for bringing it to your attention. Then, review the documentation in question and compare it with the correct information. If you find that there is indeed an error, make the necessary corrections and inform your supervisor or the appropriate department about the mistake. Additionally, it may be beneficial to communicate with the patient and their insurance company to rectify any potential issues or discrepancies.
