Type 1 Excludes Help
A type 1 excludes note is a pure excludes. It means "not coded here". A type 1 excludes note indicates that the code excluded should never be used at the same time as G03. A type 1 excludes note is for used for when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Clinical Information
  • A disorder characterized by acute inflammation of the meninges of the brain and/or spinal cord.
  • A disorder characterized by inflammation of the arachnoid membrane and adjacent subarachnoid space.
  • Acute or chronic inflammation of the arachnoid membrane of the meninges most often involving the spinal cord or base of the brain. This term generally refers to a persistent inflammatory process characterized by thickening of the arachnoid membrane and dural adhesions. Associated conditions include prior surgery, infections, trauma, subarachnoid hemorrhage, and chemical irritation. Clinical features vary with the site of inflammation, but include cranial neuropathies, radiculopathies, and myelopathies. (from Joynt, Clinical Neurology, 1997, ch48, p25)
  • Brain infection
  • Inflammation of the arachnoid membrane and adjacent subarachnoid space. (on-line medical dictionary)
  • Inflammation of the coverings of the brain and/or spinal cord, which consist of the pia mater; arachnoid; and dura mater. Infections (viral, bacterial, and fungal) are the most common causes of this condition, but subarachnoid hemorrhage (hemorrhages, subarachnoid), chemical irritation (chemical meningitis), granulomatous conditions, neoplastic conditions (carcinomatous meningitis), and other inflammatory conditions may produce this syndrome. (from Joynt, Clinical Neurology, 1994, ch24, p6)
  • Inflammation of the meninges (three thin layers of tissue that cover and protect the brain and spinal cord). Meningitis is usually caused by a bacterial or viral infection, but sometimes is caused by cancer, drug allergies, or inflammatory diseases.
  • Inflammation of the meninges.
  • Meningitis is inflammation of the thin tissue that surrounds the brain and spinal cord, called the meninges. There are several types of meningitis. The most common is viral meningitis, which you get when a virus enters the body through the nose or mouth and travels to the brain. Bacterial meningitis is rare, but can be deadly. It usually starts with bacteria that cause a cold-like infection. It can block blood vessels in the brain and lead to stroke and brain damage. It can also harm other organs. pneumococcal infections and meningococcal infections can cause bacterial meningitis.anyone can get meningitis, but it is more common in people whose bodies have trouble fighting infections. Meningitis can progress rapidly. You should seek medical care quickly if you have
    • a sudden fever
    • a severe headache
    • a stiff neck
    early treatment can help prevent serious problems, including death. Vaccines can prevent some of the bacterial infections that cause meningitis. Parents of adolescents and students living in college dorms should talk to a doctor about the vaccination.
