Medical Coding And Billing Course for Beginners | ICD, CPT, HCPCS, CPC | ICD-Chapter20 - 5

So hello everyone welcome to grade

online training. So today we're going to

start with ICD 10 CM coding guidelines

for chapter 20. Chapter 20 is about

external causes of morbidity and code

ranges are B00 to Y 999. Okay. And we

have to use this external causes with

injury course. Okay. which is which is

it caused because of some external

forces or any external cause. We have to

specify that external call and for that

we have to use V00 to Y9 C. How to use

this we'll see uh in this session. So

topics covered in this class are

introduction, ICD10 coding guidelines

like general external cost coding

guidelines, place of occurrence

guidelines, activity codes, place of

occurrence activity status code use with

other external cause. Then we have if

the reporting format limits the number

of external cause codes, how to code

that? Then multiple external cause

coding guidelines. Child and adult abuse

guideline. Unknown or undetermined

intent guideline. Squally or late

effects of external cause guideline.

Then terrorism guidelines

and external cause status. Okay. And

lastly we'll see how to solve the

question and answers. Okay. So what are

external causes? Reporting external

causes of morbidity is important because

wounds, injuries, poisoning and adverse

effects of medications require reporting

of the circumstances around them as as

the cause may be bad. Okay. When we call

for any wound, injury or poisoning and

any adverse effect of any medication, we

have to use external

cause as a cause of uh that injury or

the external cause codes identify the

cause of an injury or health condition.

The intent means accidental or

intentional. If poisoning is there, then

what is that? What is intent of that

medication that is accidental or

intentional or the the place where the

incident occurred the activity of the

patient at the time of the incident and

the patient status such as civilian or

military that we can specify using the

external causes external

cause and external cause V2 Y9 are

secondary course that capture specific

details about an injury or health

event. So topics cover means uh we have

11 subchapters in chapter 20. Okay. Like

V2 X50 course we have to use for coding

accident related external causes. Okay.

means motor vehicle accident and

everything will get codes for that in B

00 to X58 course code range X71 to

X83 is for intentional self harm like if

it is something related to suicide.

Okay. X92 to Y09 is related to assault.

Then Y21 to Y3 events of undetermined

intent. Y35 to Y38 is for legal

intervention, operations of war,

military operations and terrorism. Then

Y62 to Y 84 is for complications of

medical and surgical care and Y 92 Y9 is

for supplementary factors related to

causes of

morbidity classified. Okay. So on these

types of code range is there in this

chapter. So first point in coding

guidelines mean ICD 10 coding

guidelines. Uh a point is general

external cost coding guidelines use with

first point is use with any code in the

range of

800.0 to

T88.9 and Z00 to Z99. Okay. So an

external cause code may be used with any

code in range of a

00.02 to a uh sorry

T88.9 and Z00 to Z99 classification that

represents a health condition due to an

external cause. Okay. So any health

condition cause because of external

cause. Okay. we can use this external

cause code with that condition. Okay.

And any health condition we coded from

category A00.0 to T9 88.9. Right. So we

have to use this external cause code.

Any health condition related to or cause

due to external cause. They they can be

reported with any condition due to an

external cause and are not related to

injuries or poisoning such as heart

attack that occurs during strenous

physical activity. Okay. Like that mean

external causes are not just limited to

injury or poisoning. We can use external

causes with any kind of condition. But

just one thing that our physician or in

our own question it has to be mentioned

that this condition is caused because of

some physical activity or some external

force or something. In that case we have

to use external cause. Example patient

admitted with cellulitis due to insect

bite on pigment. Okay. Here you can see

patient had cellulitis and that is

because of insect bite. Okay. So we have

to code cellulitis. How to find out this

code for cellulitis that we'll see later

on. Okay. Right now we focus on just

this external cause which is

W57 XA. So it is beaten or stung by

nonvenenomous insect and other

nonvenenomous arthropods initial in okay

how to find out this code I'll show you

to find out the external cause code you

can see here we have same uh structure

in book also okay if you when you go

through your book you can see

first normal index okay which is used

for diseases okay and then And we have

another index which named as external

cause index. Okay. And to find out the

external causes we have to follow this

index. External cause index. If you are

not right now not able to use your books

you can go through this site and start

your practice otherwise you will forgot

these things. So we need code for insect

bite right. So we have to search for

bite under the external cause index.

Please remember this external cause

index. This is not regular external

cause index. We have to search for V and

bite. So this is bite or bitten by.

Click here and search for as this is

index sorry insect. We have to search

for insect. We got the term insect.

Okay. We got category W57.

Okay, if we click W57 in the book, once

you get the W57 number, you have to go

and search in the tabular list. Okay,

that I'll show you how to search. Now,

uh in W57, we have three three codes.

Okay, W57 X A, W57 XD, W57 XS. Okay, so

what is meaning of this A? So, what is A

and all that? that we'll see

in another sessions. Okay. Now just

focus on this category. Okay. Which is

starting letters in

W57 which is used for beaten by you can

see here beaten or stung by

nonvenenomous insect and other

nonvenenomous arropods. Initial used for

initial encounter. D is used for

subsequent encounter. Okay. And S is

used for sequential. So right now this

is initial encounter okay that's why we

have to use this code W57 X and you can

see synonyms here cause of injury nomous

or insect bite okay on different

different

location can use same code so many

synonyms are the same code clear any

doubt yeah no it's good sometimes we

get specified external cost so first We

need to go and see details of that code.

Okay. Whether we have specific code or

not. Next point, external cause code

used for length of treatment. So

assigning the external cause code with

the appropriate seventh character for

each encounter for which the injury or

condition is being treated. Okay? Like

just I show you that each and every most

of the codes ends with a d and s

character. Right? The seventh character

A, D and S. So A represent initial

encounter. D is for subsequent encounter

means each encounter after initial

encounter we have to use D code or D

letter D7 letter. Then if any squella or

after effect or late effect of that

injury is there in that case we have to

use S as a seventh. Okay. So next point,

use the full range of external cause.

Use the full range of external cause to

completely describe the cause, intent,

place of occurrence and if applicable

the activity of the patient at the time

of the event. Okay. And the patient
