 Q85.03

 (SCHWANNOMATOSIS)

Schwannomatosis is a disorder characterized by multiple noncancerous (benign) tumors called schwannomas, which are a type of tumor that grows on nerves. Schwannomas develop when Schwann cells, which are specialized cells that normally form an insulating layer around the nerve, grow uncontrollably to form a tumor. Schwannomas are rarely cancerous, but they can lead to nerve damage and loss of muscle control. See your doctor if you have any unusual lumps or numbness. The life expectancy of people with schwannomatosis is normal. Schwannomatosis is usually considered to be a form of neurofibromatosis, which is a group of disorders characterized by the growth of tumors in the nervous system.

SYMPTOMS OF SCHWANNOMATOSIS

• Difficulty with urinating or bowel dysfunction.
• Facial weakness.
• Headaches.
• Lumps or swollen areas where tumors form under the skin.
• Numbness.
• Vision changes.
• Weakness.

The cause of schwannomas is not known in most cases. Most often they occur spontaneously. Genetic disorders such as Carney complex, neurofibromatosis 2 (NF2) and schwannomatosis can cause schwannomas.

Surgery is usually performed to remove schwannomas in the peripheral nervous system, although radiosurgery is commonly used for schwannomas in the head. Since they are found in the sheath surrounding the nerve, the procedure often can be completed without any damage to the nerve except for vestibular schwannomas where hearing is frequently lost after surgery. Smaller benign schwannomas may just be monitored. Other treatments, such as radiation, may be used in some cases. Malignant schwannomas may be treated with immunotherapy and chemotherapy medications as well. If a schwannoma develops on a smaller nerve, it may not be possible to separate the tumor from the nerve. If a schwannoma is not completely removed, a slow-growing recurrence may be noted.

• Q85.03 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes.
• The 2021 edition of ICD-10-CM Q85.03 became effective on October 1, 2020.
• This is the American ICD-10-CM version of Q85.03 - other international versions of ICD-10 Q85.03 may differ.

A malignant peripheral nerve sheath tumor may develop in the area treated with radiation 10 to 20 years after treatment. Noncancerous nerve tumors. Malignant peripheral nerve sheath tumors can develop from noncancerous (benign) nerve tumors, such as neurofibroma. Typically, patients remain in the hospital for 5 to 10 days after surgery to remove a spinal tumor. Physical rehabilitation is always part of the recovery process. The length of recovery time varies widely, ranging from 3 months to a year. Some tumors have no symptoms until they're large and then cause a serious, rapid decline in health. Other tumors may have symptoms that develop slowly. Common symptoms include: Headaches, which may not get better with the usual headache remedies.
