Code Classification

  • Neoplasms
    • Malignant neoplasms of mesothelial and soft tissue
      • Malignant neoplasm of other connective and soft tissue

C49.9 is a billable diagnosis code used to specify a medical diagnosis of malignant neoplasm of connective and soft tissue, unspecified. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

The following anatomical sites found in the Table of Neoplasms reference this diagnosis code given the correct histological behavior: Neoplasm, neoplastic aponeurosis ; Neoplasm, neoplastic connective tissue NEC ; Neoplasm, neoplastic connective tissue NEC extremity ; Neoplasm, neoplastic connective tissue NEC limb NEC ; Neoplasm, neoplastic lymph, lymphatic channel NEC ; Neoplasm, neoplastic lymph, lymphatic channel NEC vessel [See Also: Neoplasm, connective tissue] ; etc

Unspecified diagnosis codes like C49.9 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Clinical Classification

Clinical Information

  • Desmoplastic Small Round Cell Tumor

    a rare, aggressive soft tissue sarcoma that primarily affects adolescents and young adults. it is most commonly found in the abdomen.
  • Liposarcoma

    a malignant tumor derived from primitive or embryonal lipoblastic cells. it may be composed of well-differentiated fat cells or may be dedifferentiated: myxoid (liposarcoma, myxoid), round-celled, or pleomorphic, usually in association with a rich network of capillaries. recurrences are common and dedifferentiated liposarcomas metastasize to the lungs or serosal surfaces. (from dorland, 27th ed; stedman, 25th ed)
  • Liposarcoma, Myxoid

    a liposarcoma containing round mesenchymal cells and a myxoid extracellular matrix in stroma.
  • Rhabdomyosarcoma

    a malignant solid tumor arising from mesenchymal tissues which normally differentiate to form striated muscle. it can occur in a wide variety of sites. it is divided into four distinct types: pleomorphic, predominantly in male adults; alveolar (rhabdomyosarcoma, alveolar), mainly in adolescents and young adults; embryonal (rhabdomyosarcoma, embryonal), predominantly in infants and children; and botryoidal, also in young children. it is one of the most frequently occurring soft tissue sarcomas and the most common in children under 15. (from dorland, 27th ed; holland et al., cancer medicine, 3d ed, p2186; devita jr et al., cancer: principles & practice of oncology, 3d ed, pp1647-9)
  • Rhabdomyosarcoma, Alveolar

    a form of rhabdomyosarcoma occurring mainly in adolescents and young adults, affecting muscles of the extremities, trunk, orbital region, etc. it is extremely malignant, metastasizing widely at an early stage. few cures have been achieved and the prognosis is poor. "alveolar" refers to its microscopic appearance simulating the cells of the respiratory alveolus. (holland et al., cancer medicine, 3d ed, p2188)
  • Rhabdomyosarcoma, Embryonal

    a form of rhabdomyosarcoma arising primarily in the head and neck, especially the orbit, of children below the age of 10. the cells are smaller than those of other rhabdomyosarcomas and are of two basic cell types: spindle cells and round cells. this cancer is highly sensitive to chemotherapy and has a high cure rate with multi-modality therapy. (from holland et al., cancer medicine, 3d ed, p2188)
  • Hemangioendothelioma

    a neoplasm derived from blood vessels, characterized by numerous prominent endothelial cells that occur singly, in aggregates, and as the lining of congeries of vascular tubes or channels. hemangioendotheliomas are relatively rare and are of intermediate malignancy (between benign hemangiomas and conventional angiosarcomas). they affect men and women about equally and rarely develop in childhood. (from stedman, 25th ed; holland et al., cancer medicine, 3d ed, p1866)
  • Hemangioendothelioma, Epithelioid

    a tumor of medium-to-large veins, composed of plump-to-spindled endothelial cells that bulge into vascular spaces in a tombstone-like fashion. these tumors are thought to have "borderline" aggression, where one-third develop local recurrences, but only rarely metastasize. it is unclear whether the epithelioid hemangioendothelioma is truly neoplastic or an exuberant tissue reaction, nor is it clear if this is equivalent to kimura's disease (see angiolymphoid hyperplasia with eosinophilia). (segen, dictionary of modern medicine, 1992)
  • Lymphangiosarcoma

    a malignant tumor originating from the endothelial cells of lymphatic vessels. most lymphangiosarcomas arise in an arm secondary to radical mastectomy but they sometimes complicate idiopathic lymphedema. the lymphedema has usually been present for 6 to 10 years before malignant changes develop. (from dorland, 27th ed; holland et al., cancer medicine, 3d ed, p1866)
  • Avian Sarcoma Viruses

    group of alpharetroviruses (alpharetrovirus) producing sarcomata and other tumors in chickens and other fowl and also in pigeons, ducks, and rats.
  • Carcinoma, Renal Cell

    a heterogeneous group of sporadic or hereditary carcinoma derived from cells of the kidneys. there are several subtypes including the clear cells, the papillary, the chromophobe, the collecting duct, the spindle cells (sarcomatoid), or mixed cell-type carcinoma.
  • Dendritic Cell Sarcoma, Interdigitating

    a rare sarcoma of interdigitating cells found in the lymph nodes and non-lymphoid organs. they exhibit a variable immunophenotype and lack birbeck granules.
  • Endometrial Stromal Tumors

    neoplasms of the endometrial stroma that sometimes involve the myometrium. these tumors contain cells that may closely or remotely resemble the normal stromal cells. endometrial stromal neoplasms are divided into three categories: (1) benign stromal nodules; (2) low-grade stromal sarcoma, or endolymphatic stromal myosis; and (3) malignant endometrial stromal sarcoma (sarcoma, endometrial stromal).
  • Epsilonretrovirus

    a genus in the family retroviridae infecting fish. species include walleye dermal sarcoma virus, walleye epidermal hyperplasia virus 1, and walleye epidermal hyperplasia virus 2.
  • Gliosarcoma

    rare mixed tumors of the brain and rarely the spinal cord which contain malignant neuroectodermal (glial) and mesenchymal components, including spindle-shaped fibrosarcoma cells. these tumors are highly aggressive and present primarily in adults as rapidly expanding mass lesions. they may arise in tissue that has been previously irradiated. (from br j neurosurg 1995 apr;9(2):171-8)
  • Harvey murine sarcoma virus

    a replication-defective mouse sarcoma virus (sarcoma viruses, murine) first described by j.j. harvey in 1964.

    a species in the genus rhadinovirus, subfamily gammaherpesvirinae, isolated from patients with aids-related and "classical" kaposi sarcoma.
  • Histiocytic Sarcoma

    malignant neoplasms composed of macrophages or dendritic cells. most histiocytic sarcomas present as localized tumor masses without a leukemic phase. though the biological behavior of these neoplasms resemble lymphomas, their cell lineage is histiocytic not lymphoid.
  • Kirsten murine sarcoma virus

    a replication-defective murine sarcoma virus (sarcoma viruses, murine) capable of transforming mouse lymphoid cells and producing erythroid leukemia after superinfection with murine leukemia viruses (leukemia virus, murine). it has also been found to transform cultured human fibroblasts, rat liver epithelial cells, and rat adrenocortical cells.
  • Langerhans Cell Sarcoma

    rare malignant neoplasm of dendritic langerhans cells exhibiting atypical cytology, frequent mitoses, and aggressive clinical behavior. they can be distinguished from other histiocytic and dendritic proliferations by immunohistochemical and ultrastructure studies. cytologically benign proliferations of langerhans cells are called langerhans cell histiocytosis.
  • Lymphoma

    a general term for various neoplastic diseases of the lymphoid tissue.
  • Lymphoma, Large-Cell, Immunoblastic

    malignant lymphoma characterized by the presence of immunoblasts with uniformly round-to-oval nuclei, one or more prominent nucleoli, and abundant cytoplasm. this class may be subdivided into plasmacytoid and clear-cell types based on cytoplasmic characteristics. a third category, pleomorphous, may be analogous to some of the peripheral t-cell lymphomas (lymphoma, t-cell, peripheral) recorded in both the united states and japan.
  • Lymphoma, Non-Hodgkin

    any of a group of malignant tumors of lymphoid tissue that differ from hodgkin disease, being more heterogeneous with respect to malignant cell lineage, clinical course, prognosis, and therapy. the only common feature among these tumors is the absence of giant reed-sternberg cells, a characteristic of hodgkin's disease.
  • Mast-Cell Sarcoma

    a unifocal malignant tumor that consists of atypical pathological mast cells without systemic involvement. it causes local destructive growth in organs other than in skin or bone marrow.
  • Medulloblastoma

    a malignant neoplasm that may be classified either as a glioma or as a primitive neuroectodermal tumor of childhood (see neuroectodermal tumor, primitive). the tumor occurs most frequently in the first decade of life with the most typical location being the cerebellar vermis. histologic features include a high degree of cellularity, frequent mitotic figures, and a tendency for the cells to organize into sheets or form rosettes. medulloblastoma have a high propensity to spread throughout the craniospinal intradural axis. (from devita et al., cancer: principles and practice of oncology, 5th ed, pp2060-1)
  • Moloney murine sarcoma virus

    a replication-defective murine sarcoma virus (sarcoma viruses, murine) isolated from a rhabdomyosarcoma by moloney in 1966.
  • Neurofibrosarcoma

    a malignant tumor that arises from small cutaneous nerves, is locally aggressive, and has a potential for metastasis. characteristic histopathologic features include proliferating atypical spindle cells with slender wavy and pointed nuclei, hypocellular areas, and areas featuring organized whorls of fibroblastic proliferation. the most common primary sites are the extremities, retroperitoneum, and trunk. these tumors tend to present in childhood, often in association with neurofibromatosis 1. (from devita et al., cancer: principles & practice of oncology, 5th ed, p1662; mayo clin proc 1990 feb;65(2):164-72)

  • Sarcoma Viruses, Feline

    species of gammaretrovirus isolated from fibrosarcoma in cats. the viruses are actually recombinant feline leukemia viruses (felv) where part of the genome has been replaced by cellular oncogenes. it is unique to individuals and not transmitted naturally to other cats. fesvs are replication defective and require felv to reproduce.
  • Sarcoma Viruses, Murine

    a group of replication-defective viruses, in the genus gammaretrovirus, which are capable of transforming cells, but which replicate and produce tumors only in the presence of murine leukemia viruses (leukemia virus, murine).
  • Sarcoma, Alveolar Soft Part

    a variety of rare sarcoma having a reticulated fibrous stroma enclosing groups of sarcoma cells, which resemble epithelial cells and are enclosed in alveoli walled with connective tissue. it is a rare tumor, usually occurring between 15 and 35 years of age. it appears in the muscles of the extremities in adults and most commonly in the head and neck regions of children. though slow-growing, it commonly metastasizes to the lungs, brain, bones, and lymph nodes. (devita jr et al., cancer: principles & practice of oncology, 3d ed, p1365)
  • Sarcoma, Avian

    connective tissue tumors, affecting primarily fowl, that are usually caused by avian sarcoma viruses.
  • Sarcoma, Clear Cell

    a sarcoma of young adults occurring in the lower extremities and acral regions. it is found intimately bound to tendons as a circumscribed but unencapsulated melanin-bearing tumor of neuroectodermal origin. clear cell sarcoma is associated with a specific t(12;22)(q13;q12) translocation.
  • Sarcoma, Endometrial Stromal

  • Sarcoma, Kaposi

    a multicentric, malignant neoplastic vascular proliferation characterized by the development of bluish-red cutaneous nodules, usually on the lower extremities, most often on the toes or feet, and slowly increasing in size and number and spreading to more proximal areas. the tumors have endothelium-lined channels and vascular spaces admixed with variably sized aggregates of spindle-shaped cells, and often remain confined to the skin and subcutaneous tissue, but widespread visceral involvement may occur. kaposi's sarcoma occurs spontaneously in jewish and italian males in europe and the united states. an aggressive variant in young children is endemic in some areas of africa. a third form occurs in about 0.04% of kidney transplant patients. there is also a high incidence in aids patients. (from dorland, 27th ed & holland et al., cancer medicine, 3d ed, pp2105-7) hhv-8 is the suspected cause.

  • Sarcoma, Synovial

    a malignant neoplasm arising from tenosynovial tissue of the joints and in synovial cells of tendons and bursae. the legs are the most common site, but the tumor can occur in the abdominal wall and other trunk muscles. there are two recognized types: the monophasic (characterized by sheaths of monotonous spindle cells) and the biphasic (characterized by slit-like spaces or clefts within the tumor, lined by cuboidal or tall columnar epithelial cells). these sarcomas occur most commonly in the second and fourth decades of life. (from dorland, 27th ed; devita jr et al., cancer: principles & practice of oncology, 3d ed, p1363)
  • Sarcoma, Yoshida

    an experimental sarcoma of rats.
  • Leiomyosarcoma

    family of rna viruses that infects birds and mammals and encodes the enzyme reverse transcriptase. the family contains seven genera: deltaretrovirus; lentivirus; retroviruses type b, mammalian; alpharetrovirus; gammaretrovirus; retroviruses type d; and spumavirus. a key feature of retrovirus biology is the synthesis of a dna copy of the genome which is integrated into cellular dna. after integration it is sometimes not expressed but maintained in a latent state (proviruses).
  • Mast Cells

    granulated cells that are found in almost all tissues, most abundantly in the skin and the gastrointestinal tract. like the basophils, mast cells contain large amounts of histamine and heparin. unlike basophils, mast cells normally remain in the tissues and do not circulate in the blood. mast cells, derived from the bone marrow stem cells, are regulated by the stem cell factor.
  • Neoplasm Metastasis

    the transfer of a neoplasm from one organ or part of the body to another remote from the primary site.

Convert C49.9 to ICD-9-CM

  • ICD-9-CM Code: 171.9 - Mal neo soft tissue NOS
    Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.

Table of Neoplasms

This code is referenced in the table of neoplasms by anatomical site. For each site there are six possible code numbers according to whether the neoplasm in question is malignant, benign, in situ, of uncertain behavior, or of unspecified nature. The description of the neoplasm will often indicate which of the six columns is appropriate.

Where such descriptors are not present, the remainder of the Index should be consulted where guidance is given to the appropriate column for each morphological (histological) variety listed. However, the guidance in the Index can be overridden if one of the descriptors mentioned above is present.

Patient Education


Cancer begins in your cells, which are the building blocks of your body. Normally, your body forms new cells as you need them, replacing old cells that die. Sometimes this process goes wrong. New cells grow even when you don't need them, and old cells don't die when they should. These extra cells can form a mass called a tumor. Tumors can be benign or malignant. Benign tumors aren't cancer while malignant ones are. Cells from malignant tumors can invade nearby tissues. They can also break away and spread to other parts of the body.

Cancer is not just one disease but many diseases. There are more than 100 different types of cancer. Most cancers are named for where they start. For example, lung cancer starts in the lung, and breast cancer starts in the breast. The spread of cancer from one part of the body to another is called metastasis. Symptoms and treatment depend on the cancer type and how advanced it is. Most treatment plans may include surgery, radiation and/or chemotherapy. Some may involve hormone therapy, immunotherapy or other types of biologic therapy, or stem cell transplantation.

Connective Tissue Disorders

Your connective tissue supports many different parts of your body, such as your skin, eyes, and heart. It is like a "cellular glue" that gives your body parts their shape and helps keep them strong. It also helps some of your tissues do their work. It is made of many kinds of proteins. Cartilage and fat are types of connective tissue.

Over 200 disorders that impact connective tissue. There are different types:

  • Genetic disorders, such as Ehlers-Danlos syndrome, Marfan syndrome, and osteogenesis imperfecta
  • Autoimmune disorders, such as lupus and scleroderma
  • Cancers, like some types of soft tissue sarcoma

Each disorder has its own symptoms and needs different treatment.
