Clinical ClassificationClinical
AHRQ’s CCSR groups this code into broader clinical categories.
Clinical InformationClinical
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.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 iiiLipoma
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.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.

Metabolic Disorders
Metabolism is the process your body uses to get or make energy from the food you eat. Food is made up of proteins, carbohydrates, and fats. Chemicals in your digestive system break the food parts down into sugars and acids, your body's fuel.
