Final answer:
For a single-day procedure on the CMS-1500 form, the correct way to enter the date of service in Block 24A is to use a full four-digit year and hyphenated month and day, which is '05-10-YYYY' for May 10 of the specified year. The correct answer is 4) 05-10-YYYY.
Step-by-step explanation:
The student's question pertains to the CMS-1500 form which is used for filing outpatient claims to insurance, particularly in the United States.
In Block 24A of the CMS-1500 claim form, the dates of service for a given procedure or visit need to be filled out. For a procedure that took place on a single day, both the FROM and TO fields would be filled with the same date.
Given the date format used in this form, Option 4) 05-10-YYYY with the year fully written as a four-digit number is the correct format to enter in the TO block if a procedure was carried out on May 10, of the specified year.
