2026 ICD-10-CM Diagnosis Code Z78.9Other specified health status
ICD-10-CM Z78.9
Z78.9 is a billable ICD-10-CM diagnosis code for other specified health status. It is valid on HIPAA claims for fiscal year 2026 (October 1, 2025 through September 30, 2026). The code is not accepted as a principal diagnosis by the Medicare Code Editor and exempt from POA reporting. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Other specified status.

Medicare Code Editor checks that affect claim validity for Z78.9.
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.

Z78.9 is exempt from POA reporting on inpatient claims to general acute care hospitals. Review other POA exempt codes.

Clinical InformationClinical
Tachyphylaxis
rapidly decreasing response to a drug or physiologically active agent after administration of a few doses. in immunology, it is the rapid immunization against the effect of toxic doses of an extract or serum by previous injection of small doses. (dorland, 28th ed)Drug Resistance
diminished or failed response of an organism, disease or tissue to the intended effectiveness of a chemical or drug. it should be differentiated from drug tolerance which is the progressive diminution of the susceptibility of a human or animal to the effects of a drug, as a result of continued administration.Drug Resistance, Bacterial
the ability of bacteria to resist or to become tolerant to chemotherapeutic agents, antimicrobial agents, or antibiotics. this resistance may be acquired through gene mutation or foreign dna in transmissible plasmids (r factors).Drug Resistance, Fungal
the ability of fungi to resist or to become tolerant to chemotherapeutic agents, antifungal agents, or antibiotics. this resistance may be acquired through gene mutation.Drug Resistance, Microbial
the ability of microorganisms, especially bacteria, to resist or to become tolerant to chemotherapeutic agents, antimicrobial agents, or antibiotics. this resistance may be acquired through gene mutation or foreign dna in transmissible plasmids (r factors).Drug Resistance, Multiple
simultaneous resistance to several structurally and functionally distinct drugs.Drug Resistance, Multiple, Bacterial
the ability of bacteria to resist or to become tolerant to several structurally and functionally distinct drugs simultaneously. this resistance may be acquired through gene mutation or foreign dna in transmissible plasmids (r factors).Drug Resistance, Multiple, Fungal
the ability of fungi to resist or to become tolerant to several structurally and functionally distinct drugs simultaneously. this resistance phenotype may be attributed to multiple gene mutations.Drug Resistance, Multiple, Viral
the ability of viruses to resist or to become tolerant to several structurally and functionally distinct drugs simultaneously. this resistance phenotype may be attributed to multiple gene mutation.Drug Resistance, Neoplasm
resistance or diminished response of a neoplasm to an antineoplastic agent in humans, animals, or cell or tissue cultures.Drug Resistance, Viral
the ability of viruses to resist or to become tolerant to chemotherapeutic agents or antiviral agents. this resistance is acquired through gene mutation.Yang Deficiency
in the yin-yang system of philosophy and medicine, a lack of vital energy (called yangxu in chinese). it manifests itself in various systemic and organic diseases. (the pinyin chinese-english dictionary, 1979)Yin Deficiency
in the yin-yang system of philosophy and medicine, an insufficiency of body fluid (called yinxu), manifesting often as irritability, thirst, constipation, etc. (the pinyin chinese-english dictionary, 1979).Drug Tolerance
progressive diminution of the susceptibility of a human or animal to the effects of a drug, resulting from its continued administration. it should be differentiated from drug resistance wherein an organism, disease, or tissue fails to respond to the intended effectiveness of a chemical or drug. it should also be differentiated from maximum tolerated dose and no-observed-adverse-effect level.Yin-Yang
in chinese philosophy and religion, two principles, one negative, dark, and feminine (yin) and one positive, bright, and masculine (yang), from whose interaction all things are produced and all things are dissolved. as a concept the two polar elements referred originally to the shady and sunny sides of a valley or a hill but it developed into the relationship of any contrasting pair: those specified above (female-male, etc.) as well as cold-hot, wet-dry, weak-strong, etc. it is not a distinct system of thought by itself but permeates chinese life and thought. a balance of yin and yang is essential to health. a deficiency of either principle can manifest as disease. (encyclopedia americana)Invalidism
the incapacity to work or function normally due to prolonged disability.Information Status
a state of the information pertaining to the entity associated with a clinical study protocol indicating whether this information is active or inactive for the purpose of inclusion in the protocol planned activities.Corneal Decompensation|Corneal Endothelial Decompensation
endothelial decompensation that is manifested by opacity of the cornea. the condition often occurs as a nonspecific response to mechanical injury from incidental corneal contact by intraocular instruments during surgery; chemical injury from the improper use of intraocular drugs, drugs containing preservatives, or from residues from inadequate rinsing of detergents or other residues from surgical instruments. the most common causes of corneal endothelial decompensation in the adult population are cataract removal/iol-related endothelial loss and fuchs dystrophy. when severe, corneal endothelial decompensation requires corneal transplantation.Decompensation
the inability of an organ or organ system to maintain homeostasis due to functional overload, often caused by the presence of disease intrinsic to the organ or organ system, or dysfunction in other organ systems.

Questions About Z78.9Overview
Is Z78.9 (Other specified health status) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report other specified health status on HIPAA-covered claims from October 1, 2025 through September 30, 2026.
Can Z78.9 be a principal diagnosis?
No. The Medicare Code Editor rejects this code as a principal diagnosis because other specified health status describes a circumstance that influences health status rather than a current illness. Report it as a secondary diagnosis.
Is Z78.9 exempt from POA reporting?
Yes. CMS lists this code among those exempt from present on admission reporting, so hospitals do not assign a POA indicator for other specified health status on inpatient claims.
What is the ICD-9 equivalent of Z78.9?
Under the General Equivalence Mappings, other specified health status converts to ICD-9-CM V49.89 (conditn influ health NEC). The mapping is approximate, so confirm the match fits the documentation.
