Medical Coding And Billing Course for Beginners | ICD, CPT, HCPCS, CPC | ICD-Chapter21 - 4

online training myself Nikita. So today

we going to start with ICD 10 CM chapter

21 factor influencing health status and

contact with health services and code

ranges are Z00 to

Z99. Okay. So topics covered in this

class are introduction ICD10 coding

guidelines. First guideline will be use

of Zcodes in any healthcare setting.

Then second is Z codes indicate a reason

for an encounter and C is categories of

Z course. Okay. And lastly we'll see

question and answers. So what are Z

course? Do you know anything about Z

course? No really I don't have any idea.

No problem. So zores are codes found in

chapter 21 factor influencing health

status and contact with health services

Z00 to Z99. This is the code range for

this chapter. Okay. Of the ICD10 coding

manual. Categories Z00 to Z99 are used

in circumstances other than an encounter

for disease, injury or external cause of

morbidity. The code ranges are A 0 to

Y9. These are starting chapters of ICD10

CM. So we need

to code other circumstances other than

disease, injury and external causes of

morbidity using Z00 to

Z99 like uh some screening happen or

pre-operative examination happen or some

vaccination other health status or

something we have to code from Z course

we call it as Zcodes. Okay. uh then they

indicate a reason for encounter or

provide additional information about a

patient's encounter. Sometimes mostly

history codes also starts with G Z code

only. Okay. Z later personal history,

family history or any other history.

Okay. So these are Zcodes. We'll see

different guidelines for Gordes for

Gordes. First guideline use of Gcodes in

any healthcare setting. G codes are for

use in any healthcare setting. G-codes

may be used as either a first listed

diagnosis, first listed mean principal

diagnosis code in the inpatient setting

or secondary code or depend on

circumstances of encounter. Sometimes if

uh encounter is for pre-opterative

examination then in that time you have

to uh

code.

particular zc code as a primary

diagnosis or principal diagnosis. In

case of inpatient setting we call them

as principal diagnosis which we sequence

first. We need to sequence first. Okay.

Sometimes we need to sequence them as a

secondary code or it will sequencing is

depending on circumstances of encounter.

So certain Z codes may only be used as

first listed or principal diagnosis just

as I say pre-operative examination and

all. So B point G codes indicate reason

for an encounter or provide additional

information about patient encounter.

Gcodes are not procedure codes. These

are not procedure codes. Okay. So a

corresponding procedure code must

accompany a zc code to describe any

procedure performed. Next uh next

guideline categories of zcores contact

and exposure. Category 20 indicate

contact with and suspected exposure to

communicable diseases. Okay. So Z20

indicate contact with or suspected

exposure to or communicable diseases.

Okay. So these codes are for patient who

are suspected to have been exposed to a

disease by close personal contact with

an infected individual or are in an area

where disease is epidemic. Okay. So in

such cases we have to use G20. Category

Z77 other contact with and suspected

exposures hazardous to health

indicates contact with and suspected

exposures hazardous to health. So Z20 is

for contact with for those patient

patient who are suspected to have

exposure to disease. Okay. And

Z70 77 is for other contact or suspected

exposure to hazardous to health indicate

contact with and suspected exposure to

hazardous to health. Okay. Context or

exposure codes may be used as a first

listed code to explain an encounter for

testing or more commonly as a secondary

code to identify a potential risk. Okay.

So these codes Z20 or

G77 are used as a first listed diagnosis

to explain an encounter for testing or

more commonly as a secondary code to

identify potential risk.

Next type of G codes are inoculations

and

vaccinations. So code

G23 is for encounter for inoculations

and vaccinations. Okay, just give me a

minute and highlight this. Okay, so code

Z23 is for encounters for inoculations

and vaccinations. You have to at least

remember this starting three letters of

each and every section. Okay, so it will

be easy for you to find out the code. It

indicates that a patient is being seen

to receive a profileic inoculations

against a disease. Code Z23 may be used

as a secondary code if the inoculation

is given as a routine part of preventive

healthcare such as well baby visit.

Okay. So G23 we use for vaccination. If

any you get any question regarding

vaccination or immunization you have to

go through Z23 series. Then next point

is status codes. Status scores indicate

that patient is either a carrier of a

disease or has the sequeling or residual

effect of a past disease or condition.

This includes such things as the

presence of prosthetic or mechanical

devices resulting from past treatment.

So status codes mostly represent if any

surgery happen to that patient or any

prosthetic or mechanical device which is

resultant of any past treatment or any

past disease. Okay. So that we call as a

status course. The status code is

informative because the status may

affect the course of treatment and its

outcome. So these codes are mostly

informative codes. status codes because

they will provide information about

previous encounters or patients history

which may affect treatment and its

outcome. A status code is distinct from

a history code. These are not same as a

history code. Okay. Personal history,

private or family history codes are

different codes. Those are also start

with G codes. Status codes and history

codes are different. A history the

history code indicates that patient no

longer has the condition. Okay. But

status code we use when that patient has

currently has that particular condition

like if presence of prosthetic device

mechanical device. Okay. The history

code we use when that particular

condition is no longer present. the

status codes status G codes we'll see

these all uh now I'll show you are

status code okay so first is G14 G14 is

for genetic carrier genetic carrier

status indicates that a person carries a

gene associated with a particular

disease which may be passed off passed

to

offsprings who may develop that disease

Okay, the person does not have the

disease and is not at risk of developing

the disease. Okay, so Z codes uh sorry

Z14 category is for genetic carry.

Second G15 G15 is for genetic

susceptibility to disease and genetic

susceptibility indicates that a person

has a gene that increases the risk of

that person developing the disease.

Okay. Z14 is for genetic carrier which

state that that person carries some gene

associated with particular disease. But

Z15 is for genetic susceptibility to

disease. Sorry. G16 J16 is for

resistance to antimicrobial drugs. This

code indicates that a person has a

condition that is resistant to

antimicrobial drug

treatment. Sequence the infection code

first. When uh you need to use G16 code

resistance to antimicrobial drug, you

need to sequence infection code first.

First you need to code infection code

then you have to use G16 code.

Next G17 estrogen receptor status. G18

is for retain foreign body fragments.

G19 is for hormones sensitivity

malignancy stat status. Next is

G21. G21 is for a symptotomatic HIV

infection status. This code indicates
