Inclusion Terms

Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.

  • Multiple neurofibromas in neurofibromatosis
  • Neurofibromatosis Noonan syndrome
  • Neurofibromatosis type 1

Clinical Information

  • NEUROFIBROMATOSIS 1-. an autosomal dominant inherited disorder with a high frequency of spontaneous mutations that features developmental changes in the nervous system muscles bones and skin most notably in tissue derived from the embryonic neural crest. multiple hyperpigmented skin lesions and subcutaneous tumors are the hallmark of this disease. peripheral and central nervous system neoplasms occur frequently especially optic nerve glioma and neurofibrosarcoma. nf1 is caused by mutations which inactivate the nf1 gene genes neurofibromatosis 1 on chromosome 17q. the incidence of learning disabilities is also elevated in this condition. from adams et al. principles of neurology 6th ed pp1014 18 there is overlap of clinical features with noonan syndrome in a syndrome called neurofibromatosis noonan syndrome. both the ptpn11 and nf1 gene products are involved in the signal transduction pathway of ras ras proteins.
  • NEUROFIBROMIN 1-. a protein found most abundantly in the nervous system. defects or deficiencies in this protein are associated with neurofibromatosis 1 watson syndrome and leopard syndrome. mutations in the gene gene neurofibromatosis 1 affect two known functions: regulation of ras gtpase and tumor suppression.

Present on Admission (POA)

Q85.01 is exempt from POA reporting - The Present on Admission (POA) indicator is used for diagnosis codes included in claims involving inpatient admissions to general acute care hospitals. POA indicators must be reported to CMS on each claim to facilitate the grouping of diagnoses codes into the proper Diagnostic Related Groups (DRG). CMS publishes a listing of specific diagnosis codes that are exempt from the POA reporting requirement. Review other POA exempt codes here .

Information for Patients


Neurofibromatosis

Neurofibromatosis is a genetic disorder of the nervous system. It mainly affects how nerve cells form and grow. It causes tumors to grow on nerves. You can get neurofibromatosis from your parents, or it can happen because of a mutation (change) in your genes. Once you have it, you can pass it along to your children. Usually the tumors are benign, but sometimes they can become cancerous.

There are three types of neurofibromatosis:

  • Type 1 (NF1) causes skin changes and deformed bones. It usually starts in childhood. Sometimes the symptoms are present at birth.
  • Type 2 (NF2) causes hearing loss, ringing in the ears, and poor balance. Symptoms often start in the teen years.
  • Schwannomatosis causes intense pain. It is the rarest type.

Doctors diagnose the different types based on the symptoms. Genetic testing is also used to diagnose NF1 and NF2. There is no cure. Treatment can help control symptoms. Depending on the type of disease and how serious it is, treatment may include surgery to remove tumors, radiation therapy, and medicines.

Neurofibromatosis type 1 Neurofibromatosis type 1 is a condition characterized by changes in skin coloring (pigmentation) and the growth of tumors along nerves in the skin, brain, and other parts of the body. The signs and symptoms of this condition vary widely among affected people.Beginning in early childhood, almost all people with neurofibromatosis type 1 have multiple café-au-lait spots, which are flat patches on the skin that are darker than the surrounding area. These spots increase in size and number as the individual grows older. Freckles in the underarms and groin typically develop later in childhood.Most adults with neurofibromatosis type 1 develop neurofibromas, which are noncancerous (benign) tumors that are usually located on or just under the skin. These tumors may also occur in nerves near the spinal cord or along nerves elsewhere in the body. Some people with neurofibromatosis type 1 develop cancerous tumors that grow along nerves. These tumors, which usually develop in adolescence or adulthood, are called malignant peripheral nerve sheath tumors. People with neurofibromatosis type 1 also have an increased risk of developing other cancers, including brain tumors and cancer of blood-forming tissue (leukemia).During childhood, benign growths called Lisch nodules often appear in the colored part of the eye (the iris). Lisch nodules do not interfere with vision. Some affected individuals also develop tumors that grow along the nerve leading from the eye to the brain (the optic nerve). These tumors, which are called optic gliomas, may lead to reduced vision or total vision loss. In some cases, optic gliomas have no effect on vision.Additional signs and symptoms of neurofibromatosis type 1 include high blood pressure (hypertension), short stature, an unusually large head (macrocephaly), and skeletal abnormalities such as an abnormal curvature of the spine (scoliosis). Although most people with neurofibromatosis type 1 have normal intelligence, learning disabilities and attention-deficit/hyperactivity disorder (ADHD) occur frequently in affected individuals.
