To display only the principal diagnosis on a claim, which settings for I PAF 451 and I PAF 450 would you use?

• A. I PAF 451: All Lines; I PAF 450: 2
• B. I PAF 451: Selected line (first line by default); I PAF 450: 1 or Null
• C. I PAF 451: Matching lines; I PAF 450: 0
• D. I PAF 451: None; I PAF 450: 99

Answer: (B)

The idea is to show only one diagnosis line—the principal one—on the claim. By setting I PAF 451 to Selected line (first line by default), the system is instructed to display just a single diagnosis line rather than all lines. Since the principal diagnosis is typically placed on the first line, this ensures that the displayed line is the principal one. Then, setting I PAF 450 to 1 or Null indicates that the display should focus on that principal diagnosis, rather than pulling in additional lines or something else. Together, these settings produce a claim view that shows only the principal diagnosis. Other configurations would either expand to multiple lines or omit diagnoses entirely, which wouldn’t meet the requirement of displaying only the principal diagnosis.
