V44 vs V55
Good question and this is how "I" interpret it...
V44 would apply to the creation of a new tracheostomy
V55 would apply in any case where attention is given to the "artificial opening" which would include: a) the adjustment or repositioning of the catheter,
b) closure of the "artificial opening",
c) the passage of sounds or bougies from the trach,
d) reforming or reshaping of the stoma,
e) removal or replacement of the catheter,
f) toilet or cleansing(in the case of a colostomy "artificial opening")
