What does the PX and the DX mean? Is the DX principle diagnosis and PX procedure coding?::confused:

Assuming you mean standard American abbreviations for medical codes:

Dx = diagnosis
Px = prognosis

They essentially mean the same thing, but usually prognosis is a presumed diagnosis before it is finalized. Dx is final.

Px may also stand for Procedure...

You may see PDX for Principal Diagnosis which is the main reason the patient came in for their visit/treatment.
