Convert to ICD-9 General Equivalence Map
The ICD-10 and ICD-9 GEMs are used to facilitate linking between the diagnosis codes in ICD-9-CM and the new ICD-10-CM code set. The GEMs are the raw material from which providers, health information vendors and payers can derive specific applied mappings to meet their needs.

Information for Patients
Lyme disease is a bacterial infection you get from the bite of an infected tick. The first symptom is usually a rash, which may look like a bull's eye. As the infection spreads, you may have
- A fever
- A headache
- Muscle and joint aches
- A stiff neck
Lyme disease can be hard to diagnose because you may not have noticed a tick bite. Also, many of its symptoms are like those of the flu and other diseases. In the early stages, your health care provider will look at your symptoms and medical history, to figure out whether you have Lyme disease. Lab tests may help at this stage, but may not always give a clear answer. In the later stages of the disease, a different lab test can confirm whether you have it.
Antibiotics can cure most cases of Lyme disease. The sooner treatment begins, the quicker and more complete the recovery.
After treatment, some patients may still have muscle or joint aches and nervous system symptoms. This is called post-Lyme disease syndrome (PLDS). Long-term antibiotics have not been shown to help with PLDS. However, there are ways to help with the symptoms of PLDS, and most patients do get better with time.

Also called: Spinal meningitis
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. You get it 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 cause stroke, hearing loss, and brain damage. It can also harm other organs. Pneumococcal infections and meningococcal infections are the most common causes of bacterial meningitis.
Anyone can get meningitis, but it is more common in people with weak immune systems. Meningitis can get serious very quickly. You should get medical care right away if you have
- A sudden high fever
- A severe headache
- A stiff neck
- Nausea or vomiting
Early treatment can help prevent serious problems, including death. Tests to diagnose meningitis include blood tests, imaging tests, and a spinal tap to test cerebrospinal fluid. Antibiotics can treat bacterial meningitis. Antiviral medicines may help some types of viral meningitis. Other medicines can help treat symptoms.
There are vaccines to prevent some of the bacterial infections that cause meningitis.
