Specific Coding for Infectious mononucleosis
Non-specific codes like B27 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 infectious mononucleosis:
- NON-BILLABLE CODE - B27.0 for Gammaherpesviral mononucleosis
- BILLABLE CODE - Use B27.00 for Gammaherpesviral mononucleosis without complication
- BILLABLE CODE - Use B27.01 for Gammaherpesviral mononucleosis with polyneuropathy
- BILLABLE CODE - Use B27.02 for Gammaherpesviral mononucleosis with meningitis
- BILLABLE CODE - Use B27.09 for Gammaherpesviral mononucleosis with other complications
- NON-BILLABLE CODE - B27.1 for Cytomegaloviral mononucleosis
- BILLABLE CODE - Use B27.10 for Cytomegaloviral mononucleosis without complications
- BILLABLE CODE - Use B27.11 for Cytomegaloviral mononucleosis with polyneuropathy
- BILLABLE CODE - Use B27.12 for Cytomegaloviral mononucleosis with meningitis
- BILLABLE CODE - Use B27.19 for Cytomegaloviral mononucleosis with other complication
- NON-BILLABLE CODE - B27.8 for Other infectious mononucleosis
- BILLABLE CODE - Use B27.80 for Other infectious mononucleosis without complication
- BILLABLE CODE - Use B27.81 for Other infectious mononucleosis with polyneuropathy
- BILLABLE CODE - Use B27.82 for Other infectious mononucleosis with meningitis
- BILLABLE CODE - Use B27.89 for Other infectious mononucleosis with other complication
- NON-BILLABLE CODE - B27.9 for Infectious mononucleosis, unspecified
- BILLABLE CODE - Use B27.90 for Infectious mononucleosis, unspecified without complication

Clinical Information
- HERPESVIRUS 4 HUMAN-. the type species of lymphocryptovirus subfamily gammaherpesvirinae infecting b cells in humans. it is thought to be the causative agent of infectious mononucleosis and is strongly associated with oral hairy leukoplakia leukoplakia hairy; burkitt lymphoma; and other malignancies.
- INFECTIOUS MONONUCLEOSIS-. a common acute infection usually caused by the epstein barr virus herpesvirus 4 human. there is an increase in mononuclear white blood cells and other atypical lymphocytes generalized lymphadenopathy splenomegaly and occasionally hepatomegaly with hepatitis.
- FATIGUE SYNDROME CHRONIC-. a syndrome characterized by persistent or recurrent fatigue diffuse musculoskeletal pain sleep disturbances and subjective cognitive impairment of 6 months duration or longer. symptoms are not caused by ongoing exertion; are not relieved by rest; and result in a substantial reduction of previous levels of occupational educational social or personal activities. minor alterations of immune neuroendocrine and autonomic function may be associated with this syndrome. there is also considerable overlap between this condition and fibromyalgia. from semin neurol 1998;182:237 42; ann intern med 1994 dec 15;12112: 953 9
Information for Patients
Infectious Mononucleosis
Infectious mononucleosis, or "mono", is an infection usually caused by the Epstein-Barr virus. The virus spreads through saliva, which is why it's sometimes called "kissing disease." Mono occurs most often in teens and young adults. However, you can get it at any age. Symptoms of mono include
- Fever
- Sore throat
- Swollen lymph glands
Sometimes you may also have a swollen spleen. Serious problems are rare.
A blood test can show if you have mono. Most people get better in two to four weeks. However, you may feel tired for a few months afterward. Treatment focuses on helping symptoms and includes medicines for pain and fever, warm salt water gargles and plenty of rest and fluids.
