What is the purpose of diagnosis pointers on a UB-04 claim?

• A. To link the line item to relevant diagnosis codes listed on the claim.
• B. To determine the service dates.
• C. To assign revenue codes automatically.
• D. To identify the attending physician.

Answer: (A)

Diagnosis pointers on a UB-04 claim connect each service line to the specific ICD-10-CM diagnosis codes that justify the service. This linkage shows which condition supports that item, helping reviewers verify medical necessity and supporting correct DRG assignment and payment. So the main purpose is to tie the line item to the relevant diagnosis codes listed on the claim. The other aspects aren’t achieved by pointers: service dates are captured in service-date fields, revenue codes indicate department or service category rather than being driven by diagnosis pointers, and the attending physician is identified in separate physician identifier fields, not through the diagnosis pointers.
