[Linda Charlwood]

Hi Laureen,

Which would you code as the DX for a PT that presents with bacterial endocarditis due to AIDS - 421.1 or 421.0?

Thanks!!

I would code in this order: 042, 421.1

While researching answer for this question, I came across this rationale. Thought I would share it here for those who would like to understand the reasoning that supports Carolyn's correct reply.

Scroll to question 18. It provides the correct answer and supporting rationale as well as provides why the other options are incorrect.
