Alicia: Q: For glaucoma bilateral dif types and dif stages, code each
type but highest stage correct?
Thanks, Carolyn
A: The fact is that there is a specific role for this.
Now, let me just reiterate for some people what glaucoma is because you kind of have
to understand what it is to be able to code it correctly.
Glaucoma is that sight-threatening disorder.
It's marked by an increased intraocular pressure, or that's abbreviated IOP.
And the pressure which is in the eye that is too high for the optic nerve to tolerate.
But to be more specific, I've got a little diagram of what it does.
But there are two types of glaucoma -- we'll there're several types of glaucoma but there's
two main types: open angle and closed angle.
This is a closed angle view and just to see the detail on this -- this was a really good
shot and I want to show it to you.
The arrow is showing the pressure building up after the cornea.
If you go to the next page, because it shows you open and closed.
You do want to note because remember with diabetes, there's a default with type 2 diabetes
because more people have that.
This doesn't have a default but it's good to note that open angle glaucoma accounts
for 90% of all cases because it's slow and it's a progressive disease.
Whereas, close angle is more of an acute situation; it happens very quickly and it's very painful.
But most people that have glaucoma, it's open angle.
What you're seeing there, the drainage in the open angle, see behind the cornea and
the iris, all that fluid that is there, that is all pressurized; and if the fluid flow
from the back of the eye or the inside of the eye and what is between the cornea and
the iris isn't kept at an even balance pressure builds up.
But what happens with the pressure is that, you think, "Well, OK, pressure," but remember
that your eye is pressurized and all the nerves and the blood vessels are so tiny in the eye
that if you build up too much pressure it squishes them.
Let's scroll down to the next page and they show...Here's an example of normal vision
and what people see when they start getting the glaucoma, see how it circles and starts
getting darker and darker, and you actually lose that peripheral sight.
So, the progression of glaucoma if you look at the optic nerve, see the optic nerve there,
the red between the yellow lines and it's nice and fat and juicy looking.
Now, early damage though, if you look, see those lines going top to bottom they're kind
of straight; but in the second early stage one there's that starts pressing on that optic
nerve that the muscles start bowing and there's a little circle or pocket of fluid that starts
to build up and if you could see it's actually inflamed.
See the optic nerve starts getting inflamed.
Then, in the severe damage that's what you see when you look in but see how that optic
nerve is pushed out of proportion and there's a lot of pressure and fluid back there, once
you get into severe damage, there's nothing you can do, you lose your eyesight.
So, this is something you need to have checked, and lots of different things cause glaucoma,
it's not something I can put in the slide because it really would take so long.
Let's talk about the differences in coding for glaucoma: Bilateral low-tension glaucoma,
both moderate stages.
Now, there's a difference between ICD-9 and ICD-10 so I wanted to bring this out because
I found this information on a fantastic blog.
In ICD-9 you've got low tension and moderate stage glaucoma.
With glaucoma, you're going to usually have two codes: the type of glaucoma and the stage.
So, we've got bilateral, your choices are: 365.12 low tension glaucoma, 365.72 moderate
stage glaucoma.
Now, that means both eyes (bilateral), that's what we're talking laterality here.
ICD-10, though, one code, H40.1232 low-tension glaucoma, bilateral, moderate stage.
Unlike we talked before where it gives you more codes for specificity, this is one code
that covers everything.
Now, for example, let's say that the left eye has low-tension glaucoma, mild stage,
and the right eye has the same type but is moderate stage, ICD-9, how are we going to
code that?
365.12 low-tension glaucoma, 365.72 moderate-stage glaucoma.
But, let's see what we do with ICD-10, changes everything up, gives us laterality
and granularity.
Now we have H40.1221 low-tension glaucoma, left eye, mild stage.
Then, we have H40.1212 low-tension glaucoma, right eye, moderate stage.
See how much more specificity you get and there's no need for the payer to say, "Well,
we need some more information, and you're going to have to send in more documentation."
Now, the ICD-9-CM guidelines where it's still an ICD-9, so when you talk about the "guidelines
state for bilateral glaucoma when each eye is a different stage, assign one code for
the type and one for the highest glaucoma stage."
So, now we're saying, you can't get it very specific, you'll have one that's less.
You're not able to tell the difference, and you're not even able to tell if it's left
or right.
So, "Using ICD-9-CM for coding glaucoma lacks essential details of the patient's condition.
If we were looking for patient improvement we wouldn't even know we were dealing with
the involvement of both eyes and that only one was mild stage.
Of course, with ICD-10-CM laterality and 7th character extensions for stages, there are
many more code choices in the chapter.
It makes sense in offering specific data of the patient's condition and status.
When data will be needed in the future for pay-for-performance, other healthcare policies,
or disease research, the numbers will be there to be crunched."
And one more thing to make note of here guys is that with ICD-9, the reason that this question
is even on the slide is because you don't know what to do.
Now, with ICD-10, you don't have to worry about it.
See how specific it is?
Less guess work because it is very specific.
Look, they got all the information from the right eye and they got all the information
for the left eye.
No guessing about the guidelines, what do I do; there's no confusion there, very specific
and easy to code.
You're going to love ICD-10.
This is when you throw in the whoop-whoop!
