instructions: select the most appropriate response.
which information is entered in cms - 1500 blocks 9 - 9d on the primary insurance claim?
○ a. billing entity
○ b. primary insurance
○ c. employer tax identification number
○ d. supplemental plan

Explanation:

On the CMS - 1500 claim form, for the primary insurance claim, the information related to the supplemental plan (which would be relevant for secondary or additional insurance, not the primary) is entered in Blocks 9 - 9d. The primary insurance details are entered in other sections. The billing entity is related to who is submitting the claim (usually in a different block), the employer tax identification number is for employer - related tax purposes (not in these blocks for primary insurance claim info in Blocks 9 - 9d), and primary insurance is the main insurance but its specific details in these blocks would pertain to any supplemental aspects.

Answer:

d. supplemental plan
