1099-LTC showing taxable, is it an error?

Hello and thank you in advance for guidance, it is appreciated,

 

My dad received a 1099-LTC for 2024 (and we will for 2025) in the amount of around $73k.

 

Box 3 is marked "per diem", however, we did not receive a per diem. He was only reimbursed approved expenses which included CNA's, RN's, and then eventually, in 2025, a memory care facility.

 

His LTC covered up to $287 a day, but some days we spent a lot more and others, less.  We were only reimbursed for approved expenses, not the same amount every day no matter what we spent.

 

Box 4 is check as qualified contract. 

 

On my parents return for 2024 the $73k is shown as income on line 8 of 1040. 

 

QUESTION: Do I need to contact the LTC Co and ask for a corrected 1099-LTC, enter a reimbursement amount somewhere, a form to explain it's reimbursement, subtract the reimbursement from the income somewhere, or is this correct?
