2006 ICD-9-CM Volume 1 Diagnosis Codes Home > Neoplasms 140-239 > Neoplasms Of Unspecified Nature 239-239 > ICD-9-CM Diagnosis 239 Neoplasms of unspecified nature A new growth of benign or malignant tissue. (NEE-o-PLAY-zha) Abnormal and uncontrolled cell growth. 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. 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. -- 2004 (TOO-mer) An abnormal mass of tissue that results from excessive cell division. Tumors perform no useful body function. They may be benign (not cancerous) or malignant (cancerous). 239 is a non-specific code that cannot be used to specify a diagnosis ICD-9-CM Diagnosis 239.0 Neoplasm of unspecified nature of digestive system 239.0 is a specific code that can be used to specify a diagnosis ICD-9-CM Diagnosis 239.1 Neoplasm of unspecified nature of respiratory system 239.1 is a specific code that can be used to specify a diagnosis ICD-9-CM Diagnosis 239.2 Neoplasm of unspecified nature of bone soft tissue and skin 239.2 is a specific code that can be used to specify a diagnosis ICD-9-CM Diagnosis 239.3 Neoplasm of unspecified nature of breast 239.3 is a specific code that can be used to specify a diagnosis ICD-9-CM Diagnosis 239.4 Neoplasm of unspecified nature of bladder 239.4 is a specific code that can be used to specify a diagnosis ICD-9-CM Diagnosis 239.5 Neoplasm of unspecified nature of other genitourinary organs 239.5 is a specific code that can be used to specify a diagnosis 239.5 contains 2 index entries ICD-9-CM Diagnosis 239.6 Neoplasm of unspecified nature of brain Neoplasms of the intracranial components of the central nervous system, including the cerebral hemispheres, basal ganglia, hypothalamus, thalamus, brain stem, and cerebellum. Brain neoplasms are subdivided into primary (originating from brain tissue) and secondary (i.e., metastatic) forms. Primary neoplasms are subdivided into benign and malignant forms. In general, brain tumors may also be classified by age of onset, histologic type, or presenting location in the brain. Benign and malignant neoplasms that arise from or metastasize to structures within the cranium. This includes meningeal and other tumors that occur in the spaces that surround the brain, and neoplasms of the brain. 239.6 is a specific code that can be used to specify a diagnosis ICD-9-CM Diagnosis 239.7 Neoplasm of unspecified nature of endocrine glands and other parts of nervous system 239.7 is a specific code that can be used to specify a diagnosis ICD-9-CM Diagnosis 239.8 Neoplasm of unspecified nature of other specified sites 239.8 is a specific code that can be used to specify a diagnosis ICD-9-CM Diagnosis 239.9 Neoplasm of unspecified nature site unspecified 239.9 is a specific code that can be used to specify a diagnosis
