2023 ICD-10-CM Diagnosis Code D49
Neoplasms of unspecified behavior
2016 2017 2018 2019 2020 2021 2022 2023 Non-Billable/Non-Specific Code
- D49 should not be used for reimbursement purposes as there are multiple codes below it that contain a greater level of detail.
- The 2023 edition of ICD-10-CM D49 became effective on October 1, 2022.
- This is the American ICD-10-CM version of D49 - other international versions of ICD-10 D49 may differ.
Type 1 ExcludesType 1 Excludes Help
A type 1 excludes note is a pure excludes. It means "not coded here". A type 1 excludes note indicates that the code excluded should never be used at the same time as D49. A type 1 excludes note is for used for when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Clinical Information
- A benign or malignant tissue growth resulting from uncontrolled cell proliferation. Benign neoplastic cells resemble normal cells without exhibiting significant cytologic atypia, while malignant cells exhibit overt signs such as dysplastic features, atypical mitotic figures, necrosis, nuclear pleomorphism, and anaplasia. Representative examples of benign neoplasms include papillomas, cystadenomas, and lipomas; malignant neoplasms include carcinomas, sarcomas, lymphomas, and leukemias.
- A general term for autonomous tissue growth in which the malignancy status has not been established and for which the transformed cell type has not been specifically identified.
- An abnormal mass of tissue that results when cells divide more than they should or do not die when they should. Neoplasms may be benign (not cancer), or malignant (cancer).
- An abnormal tissue growth resulted from uncontrolled cell proliferation. Benign neoplastic cells resemble normal cells without exhibiting significant cytologic atypia, while malignant ones exhibit overt signs such as dysplastic features, atypical mitotic figures, necrosis, nuclear pleomorphism, and anaplasia. Representative examples of benign neoplasms include papillomas, cystadenomas, and lipomas; malignant neoplasms include carcinomas, sarcomas, lymphomas, and leukemias.
- Gradual increase in the number, the size, and the complexity of cells of an individual. Growth generally results in increase in organ weight; body weight; and body height.
- Growth of the tumor after morphology of cell has changed; cells may or may not have transformed to a cancerous state.
- Increases in physical dimensions or maturity of organ systems
- New abnormal growth of tissue. Malignant neoplasms show a greater degree of anaplasia and have the properties of invasion and metastasis, compared to benign neoplasms.
- Normal increase in bone size and body weight during growth years
- Processes that promote either specific or nonspecific formation of additional tissue mass, typically by cell proliferation.
- The increase in size or mass of an entire organism, a part of an organism or a cell. [goc:bf, goc:ma]
