Learn about Roseola infantum, including clinical features, diagnosis codes (ICD-10 B08.2, Exanthema subitum), differential diagnosis, and treatment. This resource provides information for healthcare professionals on documenting Roseola symptoms, managing the illness, and accurate medical coding for sixth disease. Find details on the characteristic rash, fever, and other associated signs for proper clinical documentation and patient care.

Is the diagnosis Roseola infantum (exanthema subitum)?
When to use each related code
| Description |
|---|
| Sudden high fever, followed by rash as fever breaks |
| Slapped cheek rash, fever, lacy body rash |
| Measles-like rash, but milder, swollen glands |
Coding Roseola as a nonspecific exanthem (e.g., R21) due to lack of provider documentation specifying HHV-6 or HHV-7.
Incorrect code assignment based on patient age, confusing Roseola infantum (B08.2) with other viral exanthems.
Failure to capture and code rare but serious Roseola complications like febrile seizures (R56.0).
Patient presents with a chief complaint of sudden high fever, typically exceeding 103 degrees Fahrenheit, which has persisted for 3-5 days. The fever is documented as high-grade and is described by the parentcaregiver as unresponsive to antipyretics. The patient may exhibit irritability, mild upper respiratory symptoms such as rhinorrhea or cough, and swollen lymph nodes, specifically cervical lymphadenopathy. Following the abrupt cessation of the fever, a characteristic maculopapular rash, described as rose-pink in color and blanching on pressure, erupted on the trunk and neck, subsequently spreading to the face and extremities. The rash is non-pruritic and typically resolves within 1-3 days without desquamation. Diagnosis of roseola infantum, also known as sixth disease or exanthem subitum, is made clinically based on the characteristic fever and rash pattern. Differential diagnosis includes rubella, measles, and other viral exanthems. Laboratory testing is not routinely indicated but may include a complete blood count demonstrating mild leukopenia or lymphocytosis. Treatment is supportive, focusing on fever management with antipyretics such as acetaminophen or ibuprofen and ensuring adequate hydration. The patient's prognosis is excellent, with complete recovery expected. Patient education provided regarding the benign nature of the illness, the importance of fever control, and recognizing signs of dehydration. Follow-up is not typically required unless complications arise. ICD-10 code B08.2 is documented for roseola infantum.
