2021 ICD-10-CM Code G05
Encephalitis, myelitis and encephalomyelitis in diseases classified elsewhere
Not Valid for Submission
G05 is a "header" nonspecific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of encephalitis, myelitis and encephalomyelitis in diseases classified elsewhere. The code is NOT valid for the year 2021 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Code Classification
Specific Coding for Encphlts, myelitis & encephalomyelitis in dis classd elswhr
Header codes like G05 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10 codes with a higher level of specificity when coding for encphlts, myelitis & encephalomyelitis in dis classd elswhr:
Tabular List of Diseases and Injuries
The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code G05:
Code First
Code FirstCertain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions, the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists, there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation.
- underlying disease, such as:
- human immunodeficiency virus HIV disease B20
- poliovirus A80
- suppurative otitis media H66.01 H66.4
- trichinellosis B75
Type 1 Excludes
Type 1 ExcludesA type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
- adenoviral encephalitis, myelitis and encephalomyelitis A85.1
- congenital toxoplasmosis encephalitis, myelitis and encephalomyelitis P37.1
- cytomegaloviral encephalitis, myelitis and encephalomyelitis B25.8
- encephalitis, myelitis and encephalomyelitis in measles B05.0
- encephalitis, myelitis and encephalomyelitis in systemic lupus erythematosus M32.19
- enteroviral encephalitis, myelitis and encephalomyelitis A85.0
- eosinophilic meningoencephalitis B83.2
- herpesviral herpes simplex encephalitis, myelitis and encephalomyelitis B00.4
- listerial encephalitis, myelitis and encephalomyelitis A32.12
- meningococcal encephalitis, myelitis and encephalomyelitis A39.81
- mumps encephalitis, myelitis and encephalomyelitis B26.2
- postchickenpox encephalitis, myelitis and encephalomyelitis B01.1
- rubella encephalitis, myelitis and encephalomyelitis B06.01
- toxoplasmosis encephalitis, myelitis and encephalomyelitis B58.2
- zoster encephalitis, myelitis and encephalomyelitis B02.0
Information for Patients
Encephalitis
Encephalitis is an inflammation of the brain. Usually the cause is a viral infection, but bacteria can also cause it. It can be mild or severe. Most cases are mild. You may have flu-like symptoms. With a mild case, you may just need rest, plenty of fluids, and a pain reliever.
Severe cases need immediate treatment. Symptoms of severe cases include
- Severe headache
- Sudden fever
- Drowsiness
- Vomiting
- Confusion
- Seizures
In babies, additional symptoms may include constant crying, poor feeding, body stiffness, and bulging in the soft spots of the skull.
Severe cases may require a stay in the hospital. Treatments include oral and intravenous (IV) medicines to reduce inflammation and treat infection. Patients with breathing difficulties may need artificial respiration. Some people may need physical, speech, and occupational therapy once the illness is under control.

Spinal Cord Diseases
Your spinal cord is a bundle of nerves that runs down the middle of your back. It carries signals back and forth between your body and your brain. It is protected by your vertebrae, which are the bone disks that make up your spine. If you have an accident that damages the vertebrae or other parts of the spine, this can also injure the spinal cord. Other spinal cord problems include
- Tumors
- Infections such as meningitis and polio
- Inflammatory diseases
- Autoimmune diseases
- Degenerative diseases such as amyotrophic lateral sclerosis and spinal muscular atrophy
Symptoms vary but might include pain, numbness, loss of sensation and muscle weakness. These symptoms can occur around the spinal cord, and also in other areas such as your arms and legs. Treatments often include medicines and surgery.

- Spinal tumor (Medical Encyclopedia)
- Subacute combined degeneration (Medical Encyclopedia)
