Other intellectual disabilities (F78)

Browse all the diagnosis codes used for other intellectual disabilities (f78). 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

Acromegaly - A condition caused by prolonged exposure to excessive HUMAN GROWTH HORMONE in adults. It is characterized by bony enlargement of the FACE; lower jaw (PROGNATHISM); hands; FEET; HEAD; and THORAX. The most common etiology is a GROWTH HORMONE-SECRETING PITUITARY ADENOMA. (From Joynt, Clinical Neurology, 1992, Ch36, pp79-80)

Craniosynostoses - Premature closure of one or more CRANIAL SUTURES. It often results in plagiocephaly. Craniosynostoses that involve multiple sutures are sometimes associated with congenital syndromes such as ACROCEPHALOSYNDACTYLIA; and CRANIOFACIAL DYSOSTOSIS.

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.

Growth Hormone-Secreting Pituitary Adenoma - A pituitary tumor that secretes GROWTH HORMONE. In humans, excess HUMAN GROWTH HORMONE leads to ACROMEGALY.

Hypohidrosis - Abnormally diminished or absent perspiration. Both generalized and segmented (reduced or absent sweating in circumscribed locations) forms of the disease are usually associated with other underlying conditions.

Lumbosacral Region - Region of the back including the LUMBAR VERTEBRAE, SACRUM, and nearby structures.

Mongolian Spot - A bluish-gray to gray-brown benign, melanocytic nevus found usually in the LUMBOSACRAL REGION of dark-skinned people, especially those of East Asian ancestry. It is usually congenital or appears shortly after birth, and disappears in childhood.

Open Bite - A condition in which certain opposing teeth fail to establish occlusal contact when the jaws are closed.

Plagiocephaly - The condition characterized by uneven or irregular shape of the head often in parallelogram shape with a flat spot on the back or one side of the head. It can either result from the premature CRANIAL SUTURE closure (CRANIOSYNOSTOSIS) or from external forces (NONSYNOSTOTIC PLAGIOCEPHALY).

Plagiocephaly, Nonsynostotic - A deformity of the SKULL that is not due to bone fusion (SYNOSTOSIS), such as craniosynostoses, and is characterized by an asymmetric skull and face. It is observed with an increased frequency in INFANTS after the adoption of supine sleeping recommendations to prevent SUDDEN INFANT DEATH SYNDROME.

Prune Belly Syndrome - A syndrome characterized by abdominal wall musculature deficiency, cryptorchism, and urinary tract abnormalities. The syndrome derives its name from its characteristic distended abdomen with wrinkled skin.

Talipes Cavus - A foot deformity in which the arch of the foot is high and often the heel adducted.

Tetralogy of Fallot - A combination of congenital heart defects consisting of four key features including VENTRICULAR SEPTAL DEFECTS; PULMONARY STENOSIS; RIGHT VENTRICULAR HYPERTROPHY; and a dextro-positioned AORTA. In this condition, blood from both ventricles (oxygen-rich and oxygen-poor) is pumped into the body often causing CYANOSIS.
