Benign lipomatous neoplasm (D17)

Benign lipomatous neoplasm, coded under D17 in ICD-10, refers to non-cancerous tumors made up of fatty tissue, commonly called lipomas. These codes specify the location of the lipoma, such as skin, subcutaneous tissue, or internal organs, aiding precise identification and treatment planning.

The ICD-10 code for benign lipomatous neoplasm is D17, with detailed subcodes indicating specific sites. For example, D17.0 covers lipomas on the head, face, and neck; referred to by synonyms like “lipoma of orbit” or “lipoma of eyebrow.” Codes D17.1 and D17.2 identify lipomas on the trunk and limbs, respectively, including areas such as the chest wall and upper arm. Internal sites like the intrathoracic organs (D17.4) and intra-abdominal organs (D17.5) are also classified here. The section includes codes for more specific locations such as kidney (D17.71) and spermatic cord (D17.6). Using these precise codes helps differentiate lipomas from other benign tumors and facilitates accurate medical documentation, billing, and tracking of conditions like “angiomyolipoma” or "lipoma of breast," commonly associated with these codes.

Clinical Terms

The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.

Adipocytes

Cells in the body that store FATS, usually in the form of TRIGLYCERIDES. WHITE ADIPOCYTES are the predominant type and found mostly in the abdominal cavity and subcutaneous tissue. BROWN ADIPOCYTES are thermogenic cells that can be found in newborns of some species and hibernating mammals.

Adipose Tissue

Specialized connective tissue composed of fat cells (ADIPOCYTES). It is the site of stored FATS, usually in the form of TRIGLYCERIDES. In mammals, there are two types of adipose tissue, the WHITE FAT and the BROWN FAT. Their relative distributions vary in different species with most adipose tissue being white.

Adiposis Dolorosa

A rare disease characterized by multiple tumor-like fatty deposits that press on nerves in various sites causing pain and weakness. Often these lipoma-like structures are located on the trunk and limbs but not on the face and hands.

Angiolipoma

A benign neoplasm composed of a mixture of adipose tissue and blood vessels. (Dorland, 27th ed)

Angiomyolipoma

A benign tumor containing vascular, adipose, and muscle elements. It occurs most often in the kidney with smooth muscle elements (angiolipoleiomyoma) in association with tuberous sclerosis. (Dorland, 27th ed)

Familial Multiple Lipomatosis

A rare autosomal disorder characterized by numerous encapsulated lipomas on the trunk and extremities. The lipomas are usually not painful but can cause pain when growing. In rare cases, one lipoma can become painful and progress to multiple painful lipomas; it is then referred to as Dercum's Disease Type III

Lipoblastoma

Benign tumors of fatty tissues found in infancy and childhood. It is associated chromosomal aberrations that result in activation of an oncogene on chromosome band 8q12.

Lipoma

A benign tumor composed of fat cells (ADIPOCYTES). It can be surrounded by a thin layer of connective tissue (encapsulated), or diffuse without the capsule.

Lipomatosis

A disorder characterized by the accumulation of encapsulated or unencapsulated tumor-like fatty tissue resembling LIPOMA.

Lipomatosis, Multiple Symmetrical

A condition characterized by the growth of unencapsulated masses of ADIPOSE TISSUE symmetrically deposited around the neck, shoulders, or other sites around the body.

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)
