What is the maximum number of modifiers that can be reported on a CMS-1500 claim form in Block 24D?

• A. 2
• B. 3
• C. 4
• D. 5

Answer: (C)

Modifiers provide extra detail about a CPT/HCPCS code that can affect payment or how the service is performed. On a CMS-1500 claim, the space allocated for modifiers on each service line allows up to four modifiers to be reported. This means you can attach four distinct modifiers to describe the service fully, using the designated modifier positions in the form. If more than four modifiers are needed, you would typically use additional line items or review payer guidance, but the form itself caps the number at four.
