Other infectious mononucleosis with other complication
ICD-10 B27.89 is a billable code used to indicate a diagnosis of other infectious mononucleosis with other complication.
Infectious mononucleosis is primarily caused by the Epstein-Barr virus (EBV), but other viral agents such as cytomegalovirus (CMV) and human immunodeficiency virus (HIV) can also lead to similar clinical presentations. The condition is characterized by fever, sore throat, lymphadenopathy, and fatigue. In cases coded as B27.89, patients may experience complications such as splenic rupture, hepatitis, or secondary infections. Diagnosis typically involves serological tests for heterophile antibodies (Monospot test), EBV-specific antibodies, and complete blood counts showing atypical lymphocytes. Antiviral treatments are generally not indicated for EBV, but supportive care is crucial. In cases where CMV is the causative agent, antiviral medications like ganciclovir may be used. Accurate coding requires thorough documentation of the specific viral etiology and any complications that arise, as these can significantly impact treatment and management.
Detailed clinical notes on the patient's history, examination findings, and laboratory results.
Patients presenting with fever, lymphadenopathy, and fatigue, requiring differential diagnosis.
Documentation must clearly state the viral cause and any complications to support the use of B27.89.
Comprehensive patient history and physical examination notes, including symptom duration and severity.
Initial evaluation of suspected mononucleosis in adolescents and young adults.
Primary care providers should ensure follow-up documentation reflects any complications or changes in the patient's condition.
Used to confirm EBV infection in suspected cases of mononucleosis.
Document the reason for testing and results.
Infectious disease specialists may require additional serological tests.
Common complications include splenic rupture, hepatitis, and secondary infections, which must be documented to support the use of this code.
