Infectious mononucleosis, unspecified without complication
ICD-10 B27.90 is a billable code used to indicate a diagnosis of infectious mononucleosis, unspecified without complication.
Infectious mononucleosis, commonly referred to as mono, is primarily caused by the Epstein-Barr virus (EBV), a member of the herpesvirus family. It is characterized by fever, sore throat, swollen lymph nodes, and fatigue. The condition is often diagnosed in adolescents and young adults, although it can occur at any age. The diagnosis is typically made based on clinical presentation and confirmed through laboratory tests, including heterophile antibody tests (such as the Monospot test) and specific EBV serologies. While most cases are self-limiting, complications can arise, such as splenic rupture or secondary infections, although these are not included in this code. Treatment is generally supportive, focusing on symptom relief, as there are no specific antiviral medications approved for treating mono. Patients are advised to rest, stay hydrated, and manage pain with over-the-counter analgesics. Understanding the nuances of this condition is crucial for accurate coding and billing, especially in differentiating it from other similar viral infections.
Detailed patient history, physical examination findings, and laboratory test results.
Patients presenting with fatigue, sore throat, and lymphadenopathy.
Ensure that all symptoms and test results are documented to support the diagnosis.
Comprehensive evaluation of patient history, including exposure history and serological testing.
Patients with atypical presentations or those requiring further evaluation for complications.
Consideration of differential diagnoses and potential co-infections.
Used to confirm the diagnosis of infectious mononucleosis.
Document the reason for the test and the results.
Ensure that the test is ordered based on clinical suspicion.
Common symptoms include fever, sore throat, swollen lymph nodes, and fatigue. Some patients may also experience headaches, rash, and loss of appetite.
Diagnosis is typically made based on clinical symptoms and confirmed through laboratory tests, including the Monospot test and specific EBV serologies.
Treatment is primarily supportive, focusing on rest, hydration, and pain management with over-the-counter medications. There are no specific antiviral treatments for mono.
