Tabular List of Diseases and Injuries
The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code Z79.84:
Inclusion Terms
Inclusion TermsThese terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
- Long term (current) use of oral antidiabetic drugs
Type 2 Excludes
Type 2 ExcludesA type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.
- long term current use of insulin Z79.4

Code Edits
The Medicare Code Editor (MCE) detects and reports errors in the coding of claims data. The following ICD-10 Code Edits are applicable to this code:
- Unacceptable principal diagnosis - There are selected codes that describe a circumstance which influences an individual's health status but not a current illness or injury, or codes that are not specific manifestations but may be due to an underlying cause. These codes are considered unacceptable as a principal diagnosis.
Approximate Synonyms
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Diabetic on insulin and oral treatment
- Diabetic on oral treatment
- Long-term current use of oral hypoglycemic medication
Diagnostic Related Groups - MS-DRG Mapping
The ICD-10 code Z79.84 is grouped in the following groups for version MS-DRG V39.0 What are Diagnostic Related Groups?
The Diagnostic Related Groups (DRGs) are a patient classification scheme which provides a means of relating the type of patients a hospital treats. The DRGs divides all possible principal diagnoses into mutually exclusive principal diagnosis areas referred to as Major Diagnostic Categories (MDC). applicable from 10/01/2021 through 09/30/2022.
Present on Admission (POA)
Z79.84 is exempt from POA reporting - The Present on Admission (POA) indicator is used for diagnosis codes included in claims involving inpatient admissions to general acute care hospitals. POA indicators must be reported to CMS on each claim to facilitate the grouping of diagnoses codes into the proper Diagnostic Related Groups (DRG). CMS publishes a listing of specific diagnosis codes that are exempt from the POA reporting requirement. Review other POA exempt codes here.
CMS POA Indicator Options and Definitions
POA Indicator Code | POA Reason for Code | CMS will pay the CC/MCC DRG? |
---|---|---|
Y | Diagnosis was present at time of inpatient admission. | YES |
N | Diagnosis was not present at time of inpatient admission. | NO |
U | Documentation insufficient to determine if the condition was present at the time of inpatient admission. | NO |
W | Clinically undetermined - unable to clinically determine whether the condition was present at the time of inpatient admission. | YES |
1 | Unreported/Not used - Exempt from POA reporting. | NO |
Replacement Code
Z7984 replaces the following previously assigned ICD-10 code(s):
- Z79.899 - Other long term (current) drug therapy
Convert Z79.84 to ICD-9 Code
The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code Z79.84 its ICD-9 equivalent. The approximate mapping means there is not an exact match between the ICD-10 code and the ICD-9 code and the mapped code is not a precise representation of the original code.

Information for Patients
Diabetes Medicines
What is diabetes?
Diabetes is a disease in which your blood glucose, or blood sugar, levels are too high. Glucose comes from the foods you eat. Insulin is a hormone that helps the glucose get into your cells to give them energy. If you have type 1 diabetes, your body does not make insulin. With type 2 diabetes, the more common type, your body does not make or use insulin well. Without enough insulin, too much glucose stays in your blood.
What are the treatments for diabetes?
Treatments for diabetes depend on the type. Common treatments include a diabetic meal plan, regular physical activity, and medicines. Some less common treatments are weight loss surgery for either type and an artificial pancreas or pancreatic islet transplantation for some people with type 1 diabetes.
Who needs diabetes medicines?
People with type 1 diabetes need to take insulin to control their blood sugar.
Some people with type 2 diabetes can control their blood sugar with healthy food choices and physical activity. But for others, a diabetic meal plan and physical activity are not enough. They need to take diabetes medicines.
The kind of medicine you take depends on your type of diabetes, daily schedule, medicine costs, and other health conditions.
What are the types of medicines for type 1 diabetes?
If you have type 1 diabetes, you must take insulin because your body no longer makes it. Different types of insulin start to work at different speeds, and the effects of each last a different length of time. You may need to use more than one type.
You can take insulin several different ways. The most common are with a needle and syringe, an insulin pen, or an insulin pump. If you use a needle and syringe or a pen, you have to take insulin several times during the day, including with meals. An insulin pump gives you small, steady doses throughout the day. Less common ways to take insulin include Inhalers, injection ports, and jet injectors.
In rare cases, taking insulin alone might not be enough to manage your blood sugar. Then you would need to take another diabetes medicine.
What are the types of medicines for type 2 diabetes?
There are several different medicines for type 2 diabetes. Each works in a different way. Many diabetes medicines are pills. There are also medicines that you inject under your skin, such as insulin.
Over time, you may need more than one diabetes medicine to manage your blood sugar. You might add another diabetes medicine or switch to a combination medicine. A combination medicine is a pill than contains more than one type of diabetes medicine. Some people with type 2 diabetes take both pills and insulin.
Even if you don't usually take insulin, you may need it at special times, such as during pregnancy or if you are in the hospital.
What else should I know about taking medicines for diabetes?
Even if you take medicines for diabetes, you still need to eat a healthy diet and do regular physical activity. These will help you manage your diabetes.
It is important to make sure that you understand your diabetes treatment plan. Talk to your provider about
- What your target blood sugar level is
- What to do if your blood sugar gets too low or too high
- Whether your diabetes medicines will affect other medicines you take
- Any side effects you have from the diabetes medicines
You should not change or stop your diabetes medicines on your own. Talk to your provider first.
Some people who take diabetes medicines may need medicines for high blood pressure, high cholesterol, or other conditions. This may help you avoid or control any complications of diabetes.
