Other congenital malformations of limb(s) (Q74)

Browse all the diagnosis codes used for other congenital malformations of limb(s) (q74). For easy navigation, the diagnosis codes are sorted in alphabetical order and grouped by sections. Each section is clearly marked with its description, and the corresponding three-digit code range. This format makes it simple to browse diagnosis codes in this chapter or section and find what you're looking for. We've also added green checkmark icons to label billable codes, and red warning icons for non-billable ones. This makes it easy to identify which codes can be billed.

Clinical Information

Acrocallosal Syndrome - Autosomal recessive syndrome characterized by hypogenesis or agenesis of CORPUS CALLOSUM. Clinical features include MENTAL RETARDATION; CRANIOFACIAL ABNORMALITIES; digital malformations, and growth retardation.

Arachnodactyly - An abnormal bone development that is characterized by extra long and slender hands and fingers, such that the clenched thumb extends beyond the ulnar side of the hand. Arachnodactyly can include feet and toes. Arachnodactyly has been associated with several gene mutations and syndromes.

Arthrogryposis - Persistent flexure or contracture of a joint.

Dentinogenesis Imperfecta - An autosomal dominant disorder of tooth development characterized by opalescent dentin resulting in discoloration of the teeth. The dentin develops poorly with low mineral content while the pulp canal is obliterated.

Hepatorenal Syndrome - Functional KIDNEY FAILURE in patients with liver disease, usually LIVER CIRRHOSIS or portal hypertension (HYPERTENSION, PORTAL), and in the absence of intrinsic renal disease or kidney abnormality. It is characterized by intense renal vasculature constriction, reduced renal blood flow, OLIGURIA, and sodium retention.

Hypertelorism - Abnormal increase in the interorbital distance due to overdevelopment of the lesser wings of the sphenoid.

Malignant Hyperthermia - Rapid and excessive rise of temperature accompanied by muscular rigidity following general anesthesia.

Pectus Carinatum - A developmental anomaly characterized by abnormal anterior protrusion of the STERNUM and adjacent COSTAL CARTILAGE.

Thrombocythemia, Essential - A clinical syndrome characterized by repeated spontaneous hemorrhages and a remarkable increase in the number of circulating platelets.

Thrombocytosis - Increased numbers of platelets in the peripheral blood. (Dorland, 27th ed)

A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
