Also known as
Cytomegaloviral disease
Infection caused by the cytomegalovirus (CMV).
Cytomegaloviral pneumonitis
Lung inflammation specifically due to CMV infection.
Cytomegaloviral hepatitis
Liver inflammation specifically caused by CMV infection.
Cytomegaloviral disease, unspecified
CMV infection not otherwise specified, including viremia.
Follow this step-by-step guide to choose the correct ICD-10 code.
Is the CMV viremia congenital?
Yes
Code P35.1, Congenital cytomegalovirus infection
No
Is the patient symptomatic?
When to use each related code
| Description |
|---|
| CMV viremia detectable by PCR or other methods. |
| CMV infection with symptoms like fever, fatigue, organ involvement. |
| Asymptomatic presence of CMV antibodies, indicating past exposure. |
Coding CMV viremia without specifying congenital vs. acquired or site impacts reimbursement and quality metrics. Consider B25.0, B25.1, or B25.2.
CMV viremia often occurs with other infections. CDI should query for and document all present conditions for accurate severity reflection.
Vague documentation like "CMV positive" may lead to incorrect coding. Specificity regarding viremia vs. other manifestations is crucial for compliance.
Q: What are the most effective diagnostic tests for confirming cytomegalovirus viremia in immunocompromised patients, and what are the key considerations for interpreting results?
A: Diagnosing cytomegalovirus (CMV) viremia in immunocompromised patients requires a combination of clinical suspicion and laboratory confirmation. Quantitative PCR (qPCR) is the gold standard due to its high sensitivity and ability to quantify viral load, which is crucial for monitoring treatment response and predicting disease progression. Other methods, such as pp65 antigenemia assay, are less sensitive and are generally not recommended for routine diagnosis. When interpreting qPCR results, consider the patient's specific immune status (e.g., solid organ transplant, hematopoietic stem cell transplant, HIV) as thresholds for preemptive treatment may vary. Additionally, consider the clinical context, including symptoms and other potential infections. False-positive results are possible, although rare with qPCR. Explore how different diagnostic thresholds are applied across various immunocompromised populations to optimize patient management. Consider implementing routine CMV monitoring protocols in high-risk patients to enable early detection and intervention.
Q: How does the clinical presentation of cytomegalovirus viremia differ across various immunocompromised states (e.g., transplant recipients, HIV patients), and what are the initial red flags clinicians should look for?
A: The clinical presentation of CMV viremia varies significantly depending on the patient's underlying immune deficiency. In solid organ transplant recipients, CMV can manifest as fever, leukopenia, hepatitis, pneumonitis, or gastrointestinal symptoms. Hematopoietic stem cell transplant recipients are at risk for similar manifestations, as well as graft failure. In patients with HIV, particularly those with advanced disease, CMV retinitis, colitis, or encephalitis can occur. Initial red flags for clinicians should include unexplained fever, organ-specific dysfunction (e.g., hepatitis, pneumonitis), and declining blood counts in immunocompromised individuals. Be aware that symptoms can be nonspecific, making a high index of suspicion crucial in at-risk patients. Learn more about the specific clinical manifestations and diagnostic approaches for CMV viremia in different immunocompromised populations to enhance early recognition and appropriate management.
Patient presents with signs and symptoms suggestive of cytomegalovirus viremia (CMV viremia), including [specific symptoms documented, e.g., fever, fatigue, malaise, myalgia, splenomegaly, atypical lymphocytosis]. Differential diagnosis includes infectious mononucleosis, Epstein-Barr virus infection, and other viral illnesses. Laboratory testing, including CMV PCR (polymerase chain reaction) quantitation and CMV antibody testing (IgG and IgM), was ordered to confirm the diagnosis of cytomegalovirus disease. Initial CMV viral load is [insert value and units]. Given the patient's [immune status - e.g., immunocompromised/transplant recipient/HIV positive status/pregnancy status] and clinical presentation, the diagnosis of CMV viremia is suspected. Treatment options, including antiviral therapy such as ganciclovir, valganciclovir, or foscarnet, will be considered based on disease severity, patient-specific factors, and current clinical guidelines for CMV treatment. Patient education regarding CMV transmission, precautions, and potential complications was provided. Follow-up appointments are scheduled to monitor CMV viral load, assess treatment response, and manage any potential side effects of antiviral medications. ICD-10-CM code B25.1 (Cytomegalovirus disease) and relevant CPT codes for laboratory testing and therapeutic procedures will be documented for billing and coding purposes. The patient's prognosis will be closely monitored and documented in subsequent clinical notes.
