ICD-10 Code B25.2 – Cytomegaloviral pancreatitis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B25.2 – Cytomegaloviral pancreatitis
What it is
B25.2 identifies pancreatitis caused by cytomegalovirus (CMV) infection. Use it when the medical record links pancreatic inflammation specifically to CMV.
Clinical signs
Clinical features vary; refer to documentation. Typical pancreatitis findings may include abdominal pain, nausea, vomiting, and imaging or clinical evidence of pancreatic inflammation, with CMV identified as the cause.
When to use this code
Use B25.2 when the provider documents CMV pancreatitis, CMV-induced pancreatitis, or pancreatitis due to cytomegalovirus. Apply it when the causal relationship is clearly stated in the record. If the note only says pancreatitis and CMV infection separately, check documentation.
Do not use for
Do not use this code for pancreatitis from other causes or for CMV infection without pancreatic involvement. Check documentation if the cause is unspecified or if another etiology is documented.
Coding tip
Code B25.2 only when CMV is documented as the cause of pancreatitis, not merely as a concurrent infection.
