What is the ICD-10 code for cytomegalovirus?

The ICD-10 code for cytomegalovirus varies by manifestation: B25.0 for pneumonitis, B25.8 for other diseases like colitis, and B25.9 for unspecified CMV disease.

How is congenital CMV coded in ICD-10?

Congenital cytomegalovirus infection is coded as P35.1 in ICD-10, used for neonates diagnosed within the first 21 days of life.

Compare key differences between these codes to ensure accurate selection

Code	Description	When to Use	Key Documentation
B25.0	Cytomegaloviral pneumonitis	Use when CMV is confirmed as the cause of pneumonitis.	Positive CMV PCR in bronchoalveolar lavage Radiological evidence of pneumonia
B25.8	Other cytomegaloviral diseases	Use for CMV diseases not specified elsewhere, like colitis.	Biopsy showing CMV inclusions Positive CMV PCR in stool
B25.9	Cytomegaloviral disease, unspecified	Use when CMV is confirmed but specific manifestation is not documented.	Positive CMV PCR without specific organ involvement
P35.1	Congenital cytomegalovirus infection	Use for neonates diagnosed with CMV within the first 21 days of life.	Positive CMV PCR in neonate within 21 days of birth

Documentation & Coding Risks

Avoid these common issues when documenting Cytomegalovirus.

Using general codes without specificity

Impact

Clinical: May lead to inappropriate treatment., Regulatory: Non-compliance with coding standards., Financial: Potential for reduced reimbursement.

Mitigation

Review clinical documentation, Use specific codes

Incorrect sequencing of codes

Impact

Reimbursement: Incorrect sequencing can lead to claim denials., Compliance: Non-compliance with ICD-10 guidelines., Data Quality: Inaccurate clinical data representation.

Mitigation

Always sequence the CMV code before manifestation codes.

Using unspecified codes when specific codes are available

Impact

Reimbursement: May result in lower reimbursement rates., Compliance: Fails to meet specificity requirements., Data Quality: Reduces the accuracy of health records.

Mitigation

Use specific CMV codes when manifestations are documented.

Specificity of CMV coding

Impact

Audits may focus on the specificity of CMV-related codes.

Mitigation

Ensure detailed documentation and use of specific codes.
