Wet Mount: a sample of the specimen mixed with a salt solution(or KOH) on a microscopic slide and check for bacteria, WBC and unusual cell called clue cells.If CLUE cells are present- it is BV. A sort of a HANGING DROP preparation( for the shape and motiltiy, type)
Wiffs Test:Saline/KOH is added to a sample to see a strong fishy odor is produced-meaning BV.
These two tests with PH >4.5 enough to confirm the diagnosis.
If want to be more grossly specific about the bacteria (Gram + or Gram –), take another slide Smear for
Grams Stain ( a dry test method).eg, type of bacteria, fungi or Gardenella can be tentatively clued by this. This is a sort of a
gold standard test.
So as Curtis said you have to report 2codes if two preprations taken 1)Wet mount 2) Smear for Grams Stain.
Wet mount report 87210. Grams stain Smear: 87205.
The
diagnosis Code:616.10/ .1x , if the doctor documented it.
IF WET MOUNT AND WIFF TEST ARE THE ONLY DOCUMENTED PROCEDURES :
My suggestions are:
So far there is no code for Wiffs test directly but I could find
odor Test which correlates well with:
the amine odor of the vaginal fluid qualitative -82120 – Vaginal fluid , Amines qualitative for reporting wiffs Test And 87210 for wet mount.
Both these tests are done at the office visit by the treating Physician because these are basic tests for which they are already trained very well.
Did your Physician perform PH value test? Then it also adds up to the diagnosis.
Hope it would help.
