The following list of clinical terms are approximate synonyms, alternative descriptions, or common phrases that might be used by patients, healthcare providers, or medical coders to describe the same condition. These synonyms and related diagnosis terms are often used when searching for an ICD-10 code, especially when the exact medical terminology is unclear. Whether you're looking for lay terms, similar diagnosis names, or common language alternatives, this list can help guide you to the correct ICD-10 classification.

Clinical Classifications group individual ICD-10-CM diagnosis codes into broader, clinically meaningful categories. These categories help simplify complex data by organizing related conditions under common clinical themes.

They are especially useful for data analysis, reporting, and clinical decision-making. Even when diagnosis codes differ, similar conditions can be grouped together based on their clinical relevance. Each category is assigned a unique CCSR code that represents a specific clinical concept, often tied to a body system or medical specialty.

CCSR Code: SKN007

Inpatient Default: Y - Yes, default inpatient assignment for principal diagnosis or first-listed diagnosis.

Outpatient Default: Y - Yes, default outpatient assignment for principal diagnosis or first-listed diagnosis.

autosomal recessive disorder characterized by hyaline deposition in the skin, bone, gastrointestinal tract, muscles and glands; multiple subcutaneous skin nodules; gingival hypertrophy; and joint contractures. mutations in the capillary morphogenesis protein-2 are associated with the disorder.

an inherited disorder of connective tissue with extensive degeneration and calcification of elastic tissue primarily in the skin, eye, and vasculature. at least two forms exist, autosomal recessive and autosomal dominant. this disorder is caused by mutations of one of the atp-binding cassette transporters. patients are predisposed to myocardial infarction and gastrointestinal hemorrhage.

a cutaneous necrobiotic disorder characterized by firm, yellow plaques or nodules, often in a periorbital distribution. it is often accompanied by an elevated erythrocyte sedimentation rate; leukopenia; and monoclonal gammopathy (igg-kappa type) and systemic involvement.

abnormal communication between two arteries that may result from injury or occur as a congenital abnormality.

an abnormal direct communication between an artery and a vein without passing through the capillaries. an a-v fistula usually leads to the formation of a dilated sac-like connection, arteriovenous aneurysm. the locations and size of the shunts determine the degree of effects on the cardiovascular functions such as blood pressure and heart rate.

abnormal passage in any organ of the biliary tract or between biliary organs and other organs.

an abnormal passage or communication between a bronchus and another part of the body.

an acquired or spontaneous abnormality in which there is communication between cavernous sinus, a venous structure, and the carotid arteries. it is often associated with head trauma, specifically basilar skull fractures (skull fracture, basilar). clinical signs often include vision disorders and intracranial hypertension.

a plant genus of the family fabaceae. many species of this genus, including the medicinal c. senna and c. angustifolia, have been reclassified into the senna genus (senna plant) and some to chamaecrista.

an abnormal passage or communication leading from an internal organ to the surface of the body.

an abnormal passage in the oral cavity on the gingiva.

an abnormal passage communicating between any components of the digestive system, or between any part of the digestive system and surrounding organ(s).

abnormal passage communicating with the esophagus. the most common type is tracheoesophageal fistula between the esophagus and the trachea.

abnormal communication most commonly seen between two internal organs, or between an internal organ and the surface of the body.

abnormal passage communicating with the stomach.

an abnormal anatomical passage between the intestine, and another segment of the intestine or other organs. external intestinal fistula is connected to the skin (enterocutaneous fistula). internal intestinal fistula can be connected to a number of organs, such as stomach (gastrocolic fistula), the biliary tract (cholecystoduodenal fistula), or the urinary bladder of the urinary tract (colovesical fistula). risk factors include inflammatory processes, cancer, radiation treatment, and surgical misadventures (medical errors).

an abnormal passage within the mouth communicating between two or more anatomical structures.

a fistula between the maxillary sinus and the oral cavity.

abnormal passage communicating with the pancreas.

surgical portasystemic shunt between the portal vein and inferior vena cava.

an abnormal anatomical passage connecting the rectum to the outside, with an orifice at the site of drainage.

an abnormal anatomical passage between the rectum and the vagina.

an abnormal passage communicating between any component of the respiratory tract or between any part of the respiratory system and surrounding organs.

a fistula between a salivary duct or gland and the cutaneous surface of the oral cavity.

abnormal passage between the esophagus and the trachea, acquired or congenital, often associated with esophageal atresia.

an abnormal passage in the urinary bladder or between the bladder and any surrounding organ.

an abnormal passage in any part of the urinary tract between itself or with other organs.

an abnormal anatomical passage that connects the vagina to other organs, such as the bladder (vesicovaginal fistula) or the rectum (rectovaginal fistula).

an abnormal passage between two or more blood vessels, between arteries; veins; or between an artery and a vein.

an abnormal anatomical passage between the urinary bladder and the vagina.

the vessels carrying blood away from the heart.

an organ of digestion situated in the left upper quadrant of the abdomen between the termination of the esophagus and the beginning of the duodenum.

a nodular organ in the abdomen that contains a mixture of endocrine glands and exocrine glands. the small endocrine portion consists of the islets of langerhans secreting a number of hormones into the blood stream. the large exocrine portion (exocrine pancreas) is a compound acinar gland that secretes several digestive enzymes into the pancreatic ductal system that empties into the duodenum.

the distal segment of the large intestine, between the sigmoid colon and the anal canal.

a musculomembranous sac along the urinary tract. urine flows from the kidneys into the bladder via the ureters (ureter), and is held there until urination.

the duct which coveys urine from the pelvis of the kidney through the ureters, bladder, and urethra.

human abcc6 wild-type allele is located in the vicinity of 16p13.1 and is approximately 75 kb in length. this allele, which encodes multidrug resistance-associated protein 6, plays a role in the active transport of drugs across the plasma membrane. mutation of the gene is associated with pseudoxanthoma elasticum and generalized arterial calcification of infancy type 2.

a rare, progressive, autosomal recessive inherited disorder caused by mutations in the abcc6 gene. it is characterized by calcification and fragmentation of the elastic fibers of the skin, retina, and cardiovascular system. signs and symptoms include skin plaques and bumps, thickened skin, retinal hemorrhage and obstruction of the blood vessels.

an autosomal recessive subtype of hereditary spastic paraplegia caused by mutation(s) in the cyp2u1 gene, encoding cytochrome p450 2u1.

a crust that covers necrotic tissue in the skin that is caused by a burn or gangrene.

a rare, autosomal dominant inherited syndrome caused by mutations in the fbn1 gene. it is characterized by hard and thickened skin, usually over the entire body, and limited joint motility.

Below are the ICD-9 codes that most closely match this ICD-10 code, based on the General Equivalence Mappings (GEMs). This ICD-10 to ICD-9 crosswalk tool is helpful for coders who need to reference legacy diagnosis codes for audits, historical claims, or approximate code comparisons.

ICD-9-CM: 709.8

Approximate Flag - The approximate mapping means this ICD-10 code does not have an exact ICD-9 equivalent. The matched code is the closest available option, but it may not fully capture the original diagnosis or clinical intent.
