Other cytomegaloviral diseases

This code represents cytomegalovirus (CMV) infections affecting organ systems other than those specified by more precise CMV codes (e.g., CMV pneumonia, retinitis, hepatitis). It signifies a systemic or localized CMV infection that doesn't have a dedicated, more specific ICD-10-CM code.

Use this code when documentation confirms a CMV infection manifesting in a non-specified organ or system, such as CMV enteritis, colitis, or encephalitis, when a more specific code for that manifestation is unavailable. It is appropriate when the physician explicitly diagnoses "other cytomegaloviral disease" or a CMV infection of an unspecified site.

• Do not use this code if a more specific CMV code exists for the documented manifestation (e.g., B25.0 for CMV pneumonitis).
• Ensure documentation clearly states CMV as the causative agent for the "other" disease process.
• Consider sequencing this code after the primary diagnosis if the CMV infection is a complication or secondary condition.
