ICD-9-CM 759.81 is a billable medical code that can be used to indicate a diagnosis on a reimbursement claim, however, 759.81 should only be used for claims with a date of service on or before September 30, 2015. For claims with a date of service on or after October 1, 2015, use an equivalent ICD-10-CM code (or codes).
2015/16 ICD-10-CM Q87.1 Congenital malformation syndromes predominantly associated with short stature
Prader Willi syndrome
A genetic syndrome caused by deletions or disruptions of chromosome 15. It is characterized by reduced fetal activity, mental retardation, hypotonia, short stature, and hypogonadism
A syndrome characterized at birth by the lack of spontaneous movements and protective reflexes, thus giving an appearance of severe brain damage. Profound hypotonia may cause asphyxia. Sucking and swallowing reflexes are absent or decreased. Deficient thermoregulation, amyotonia, and hypogonadism are usually associated. After a few weeks or months, the affected infants become more responsive and more alert. Areflexia disappears gradually but hypotonia may persist longer. This phase is marked mainly by mental subnormality, delayed growth and motor development, speech defect, lack of emotional control, voracious appetite leading to obesity, hypotonia, hyperlaxity, delayed bone maturation, and multiple orofacial and other disoders. There is a tendency to develop diabetes mellitus and cardiac failure in some patients. Pain insensitivity is common. Prader-willi habitus associated with osteopenia and camptodactyly is known as the urban-rogers-meyer syndrome
An autosomal dominant disorder caused by deletion of the proximal long arm of the paternal chromosome 15 (15q11-q13) or by inheritance of both of the pair of chromosomes 15 from the mother (uniparental disomy) which are imprinted (genetic imprinting) and hence silenced. Clinical manifestations include mental retardation; muscular hypotonia; hyperphagia; obesity; short stature; hypogonadism; strabismus; and hypersomnolence. (menkes, textbook of child neurology, 5th ed, p229)
Congenital neurobehavioral disorder characterized by rounded face, low forehead, almond shaped eyes, squinting, hypogonadism, hypotonia, insatiable appetite leading to obesity, and mental retardation; chromosomal disorder usually associated with a deletion of the proximal portion of the long arm of chromosome 15
Prader-willi syndrome (pws) is an uncommon genetic disorder. It causes poor muscle tone, low levels of sex hormones and a constant feeling of hunger. The part of the brain that controls feelings of fullness or hunger does not work properly in people with pws. They overeat, leading to obesity.babies with pws are usually floppy, with poor muscle tone, and have trouble sucking. Boys may have undescended testicles. Later, other signs appear. These include
poor motor skills
underdeveloped sex organs
mild mental retardation and learning disabilities
there is no cure for pws. Growth hormone and exercise can help build muscle mass and control weight. nih: national institute of child health and human development
ICD-9-CM codes are used in medical billing and coding to describe diseases, injuries, symptoms and conditions. ICD-9-CM 759.81 is one of thousands of ICD-9-CM codes used in healthcare. Although ICD-9-CM and CPT codes are largely numeric, they differ in that CPT codes describe medical procedures and services. Can't find a code?
