Preventive Care Science and research have provided us with a better understanding of disease and disease progression, as well as etiology. This knowledge has evolved into improved preventive care services to stop the onset of illness or injury. Learning Outcome:

Early Detection Routine and administrative exams ensure continued good health by looking for signs of disease as early as detection may be possible. Commonly, these health care encounters are known as annual physicals, well-baby checks, or well-woman exams. Learning Outcome:

These routine encounters, most often prompted by the calendar, are reported with Z codes. – Z00.00, Encounter for general adult medical examination without abnormal findings. A screening is a test or examination, such as routine lab work or imaging services, administered when there are no current signs, symptoms, or related diagnosis. Learning Outcome:

Genetic Susceptibility A patient might be a carrier or suspected carrier of a disease. The patient may have an abnormal gene that may increase a patient’s chances of developing a disease. In most cases, documentation will note that the patient has a family history of a condition, such as code Z80.6, Family history of leukemia. Learning Outcome:

Observation There might be a reason that a physician suspects a patient may be ill despite the absence of signs and symptoms. Code categories Z03 and Z04 enable you to report the reason these types of encounters are medically necessary. Learning Outcome:

Continuing Care and Aftercare Chronic illness may require long-term use of medication, known as drug therapy. When a patient is taking any type of pharmaceutical on an ongoing basis, regular monitoring can identify potential concerns, such as side effects or loss of potency. Learning Outcome:

When coding an encounter for such monitoring, you may begin with Z51.81, Encounter for therapeutic drug level monitoring, along with a code to identify the type of therapeutic drug, such as Z79.01, Long term (current) use of anticoagulants, or Z79.811, Long term (current) use of aromatase inhibitors.

Obstetrics (Prenatal) and Neonatal Exams Once the baby has arrived, the outcome of delivery, birth status, and health supervision and observations of an infant or child are all reported with a Z code such as Z , Health examination for newborn under 8 days old.

Organ Donation The number of organs and tissues that can be successfully transplanted has dramatically increased over the years, and many can be provided by a living donor. Code category Z52, Donors of organs and tissues, includes various types of blood donors (Z52.0), skin donors (Z52.1), and bone donors (Z52.2). Learning Outcome:

The donations of any of these organs would almost always be used as an allogeneic donation to another individual. A donation from the recipient’s monozygotic twin is called isogeneic, while a xenogeneic donation involves a donor and recipient who are of different species. Synthetic organ and tissue replacements are referred to as prosthetic. Learning Outcome:

Resistance to Antimicrobial Drugs The World Health Organization (WHO) defines antimicrobial resistance (AMR) as the “resistance of a micro-organism to an antimicrobial medicine to which it was originally sensitive.” AMR may be the result of overuse of antibiotics.

ICD-10-CM provides a note with some directions about the proper use of the Z codes: Note: The codes in this category are provided for use as additional codes to identify the resistance and non- responsiveness of a condition to antimicrobial drugs.

Z Codes as First-Listed/Principal Diagnosis During most encounters, a Z code may be the only code you report, or it may be reported along with others, determined by the specific circumstances. Except for 20 of the Z codes, sequencing is determined by the facts of the encounter and the Official Guidelines, as explained in Sections II and III. Learning Outcome:

Chapter Summary As a professional coder, you are responsible to ensure that every physician-patient encounter is supported as medically necessary. In ICD-10-CM, virtually all of the codes used to explain these valid reasons are found in the Z code chapter
