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 guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code Z79.1:

Type 2 Excludes

Type 2 Excludes
A 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.

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.


The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

  • Long term current use of non-steroidal anti-inflammatory drug

Clinical Information

  • LONG TERM ADVERSE EFFECTS-. persistent detrimental effects from treatment for a condition. included are effects from surgery such as postoperative complications and from drug therapy such as chemically induced disorders or other therapeutics. failure to attain a desired outcome from treatment for the condition is not considered an adverse effect.
  • CANCER SURVIVORS-. persons who have experienced prolonged survival with or following neoplastic disease.
  • INSURANCE LONG TERM CARE-. health insurance to provide full or partial coverage for long term home care services or for long term nursing care provided in a residential facility such as a nursing home.
  • LONG TERM CARE-. care over an extended period usually for a chronic condition or disability requiring periodic intermittent or continuous care.
  • TIME-. the dimension of the physical universe which at a given place orders the sequence of events. mcgraw hill dictionary of scientific and technical terms 6th ed
  • HIV LONG TERMINAL REPEAT-. regulatory sequences important for viral replication that are located on each end of the hiv genome. the ltr includes the hiv enhancer promoter and other sequences. specific regions in the ltr include the negative regulatory element nre nf kappa b binding sites sp1 binding sites tata box and trans acting responsive element tar. the binding of both cellular and viral proteins to these regions regulates hiv transcription.
  • SURVIVORS-. persons who have experienced a prolonged survival after serious disease or who continue to live with a usually life threatening condition as well as family members significant others or individuals surviving traumatic life events.
  • LONG TERM POTENTIATION-. a persistent increase in synaptic efficacy usually induced by appropriate activation of the same synapses. the phenomenological properties of long term potentiation suggest that it may be a cellular mechanism of learning and memory.
  • TERMINAL REPEAT SEQUENCES-. nucleotide sequences repeated on both the 5' and 3' ends of a sequence under consideration. for example the hallmarks of a transposon are that it is flanked by inverted repeats on each end and the inverted repeats are flanked by direct repeats. the delta element of ty retrotransposons and ltrs long terminal repeats are examples of this concept.
  • HIV LONG TERM SURVIVORS-. persons who have experienced prolonged survival of hiv infection. this includes the full spectrum of untreated hiv infected long term asymptomatics to those with aids who have survived due to successful treatment.
  • LONG TERM SYNAPTIC DEPRESSION-. a persistent activity dependent decrease in synaptic efficacy between neurons. it typically occurs following repeated low frequency afferent stimulation but it can be induced by other methods. long term depression appears to play a role in memory.
  • MEMORY LONG TERM-. remembrance of information from 3 or more years previously.

Diagnostic Related Groups

The ICD-10 code Z79.1 is grouped in the following groups for version MS-DRG V37.0 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 10/01/2019 through 09/30/2020.


Present on Admission (POA)

Z79.1 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 .

Information for Patients

Pain Relievers

Pain relievers are medicines that reduce or relieve headaches, sore muscles, arthritis, or other aches and pains. There are many different pain medicines, and each one has advantages and risks. Some types of pain respond better to certain medicines than others. Each person may also have a slightly different response to a pain reliever.

Over-the-counter (OTC) medicines are good for many types of pain. There are two main types of OTC pain medicines: acetaminophen (Tylenol) and nonsteroidal anti-inflammatory drugs (NSAIDs). Aspirin, naproxen (Aleve), and ibuprofen (Advil, Motrin) are examples of OTC NSAIDs.

If OTC medicines don't relieve your pain, your doctor may prescribe something stronger. Many NSAIDs are also available at higher prescription doses. The most powerful pain relievers are opioids. They are very effective, but they can sometimes have serious side effects. There is also a risk of addiction. Because of the risks, you must use them only under a doctor's supervision.

There are many things you can do to help ease pain. Pain relievers are just one part of a pain treatment plan.
