2020 ICD-10-CM Diagnosis Code D89.81
Graft-versus-host disease
2016 2017 2018 2019 2020 Non-Billable/Non-Specific Code
- D89.81 should not be used for reimbursement purposes as there are multiple codes below it that contain a greater level of detail.
- The 2020 edition of ICD-10-CM D89.81 became effective on October 1, 2019.
- This is the American ICD-10-CM version of D89.81 - other international versions of ICD-10 D89.81 may differ.

Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation. In most cases the manifestation codes will have in the code title, "in diseases classified elsewhere." Codes with this title are a component of the etiology/manifestation convention. The code title indicates that it is a manifestation code. "In diseases classified elsewhere" codes are never permitted to be used as first listed or principle diagnosis codes. They must be used in conjunction with an underlying condition code and they must be listed following the underlying condition.

Type 1 Excludes- hyperglobulinemia NOS (R77.1)
- monoclonal gammopathy (of undetermined significance) (D47.2)
Type 2 Excludes- transplant failure and rejection (T86.-)
- A disease caused when cells from a donated stem cell graft attack the normal tissue of the transplant patient. Symptoms include jaundice, skin rash or blisters, a dry mouth, or dry eyes.
- An incompatibility reaction (which may be fatal) in a subject (host) of low immunological competence (deficient lymphoid tissue) who has been the recipient of immunologically competent lymphoid tissue from a donor who lacks at least one antigen possessed by the recipient host; the reaction, or disease, is the result of action of the transplanted cells against those host tissues that possess the antigen not possessed by the donor. Seen most commonly following bone marrow transplantation, acute disease is seen after 5-40 days and chronic disease weeks to months after transplantation, affecting, principally, the gastrointestinal tract, liver, and skin.
- Caused by immunologically competent t cells in the graft recognizing and attacking host tissues as foreign; clinical symptoms include skin rashes, diarrhea, and abnormal liver functions.
- The clinical entity characterized by anorexia, diarrhea, loss of hair, leukopenia, thrombocytopenia, growth retardation, and eventual death brought about by the graft vs host reaction.
