FACTORS INFLUENCING HEALTH STATUS AND CONTACT
WITH HEALTH SERVICES
INTRODUCTION• Z codes are used as primary codes or secondary codes
• USE OF Z CODES IN ANY HEALTHCARE SETTING
• Z codes are for use in any healthcare setting.Z codes
may be used as either a first-listed or secondary code,
depending on the circumstances of the encounter.
certain z codes may only be used as first listed or
primary code.
• Z codes indicate reason for an encounter.
• These are not procedure codes.A corresponding
procedure code must accompany a Z code to describe
any procedure performed.
• Use codes from category z20 and z27 for patients who
have been exposed to the disease but who have no
signs and symptoms of the disease. you can use them
as a primary codes for testing encounters or as
secondary codes to supply information about risk.
• Use z23 as a secondary code when the patient has the
inoculation as part of a preventive healthcare visit.
Status codes • A status code offers information about the patient that
may affect treatment,such as presence of a prosthetic
don’t confuse status codes with history codes, which you
use when the patient does not have the condition
anymore.
• When a code description contains status code
information don’t report status code separately
• Drug use; do not use codes from category z79 for
patients addicted to drugs or in
detoxification/maintainence programmes.use drug
dependence code instead.
• Genetic susceptibility assign codes from category z15
only as a secondary code and if the patient has a gene
that increases the patient risk for that disease.
• The z code section includes codes for both personal
history and family history
• Personal history codes typically apply to conditions the
patient used to have that have the potential to occur
again.family history codes represent conditions found in
the patients family suggesting the patient may be at
higher risk for the disease.
• Use the screening z codes for tests on patients with no
signs or symptoms of the disease being tested for. if a
patient has a sign or symptom then the test is diagnostic
and a screening code is not appropriate.use the sign or
symptom code for the test encounter instead.
• A code categories include the following
1. Z11-encounter for screening for infectious and parasitic
diseases
2. Z12-encounter for screening for malignant neoplasms
3. Z13-encounter for screening for other diseases and
disorders.except z13.9 encounter for screening
unspecified
4. Z36-encounter for antenatal screening for mother
• Use observation codes only as the primary diagnosis
code. other codes may be added only if they are
unrelated to the reason for observation.
• Code Z21 on a medical record indicates that a patient is
HIV positive and developed AIDS.
• A code from category z22 on a medical record indicates
that the person is capable of transmitting the infection of
an organism and is showing symptoms of that disease
• Code z33.1 pregnant state, incidental should always be
assigned as secondary/additional diagnosis.
• A code from z 79 category may be assigned if a patient
is receiving a medication for an extended period as a
prophylactic measure
• Personal history z codes explain a patients past medical
condition that no longer exists and is not receiving any
treatment and that has no potential for recurrence.
• Family history z codes may be used with screening
codes and personal history z codes with follow-up codes.
• History z codes are used on any medical record
regardless of reason for visit
• Testing a person to rule out or confirm a suspected
condition because the patient has some signs or
symptoms is considered as screening examination and
the visit should be coded with a code for screening
• A screening code is not necessary if the screening is
inherent to a routine examination
• If a condition is confirmed during screening the z code
for screening should not be coded instead only the
confirmed diagnosis should be coded
• Observation codes are to be used as additional
diagnosis always
• Status z codes may be used with aftercare z codes
• A status z code should not be used along with a z code
for aftercare if the aftercare code indicates the type of
status
• A follow up z code indicates that visit is for ongoing care
of a healing condition or its sequelae.
• Z code for follow up examination after surgery should be
coded with history code for the condition treated and
follow up code should be sequenced first followed by the
history code.
• If a condition treated is found to have recurred on a
follow up visit then code only for the recurred condition
• Autologus organ donation conditions may be coded with
a code from category z52
• Counseling z codes are not reported with a diagnosis
code when the counseling component of care is
considered integral to standard treatment
• Codes from z37 category should always assign as
secondary codes
• Codes from z34 category are always used as primary
codes
• A code from category z40.0 encounter for prophylactic
surgery for risk factors related to neoplasms may be
assigned for the removal of ovaries for the treatment of
uterine cancer.
