ICD-10 Code B97.2 – Coronavirus as the cause of diseases classified elsewhere (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B97.2 – Coronavirus as the cause of diseases classified elsewhere
What it is
B97.2 identifies coronavirus as the infectious agent causing another condition. Use it when documentation links coronavirus to a separate disease process rather than naming it as the primary diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Records may note a confirmed coronavirus infection with symptoms or complications documented under another diagnosis.
When to use this code
Use this code when the provider states coronavirus is the cause of a disease classified elsewhere, and another diagnosis captures the main condition. Pair it with the associated manifestation or complication code as documented. If the record does not clearly link the organism to the condition, check documentation.
Do not use for
Do not use B97.2 for coronavirus infection when the encounter is coded to the infection itself or when the organism is not documented as causative. Check documentation for the correct principal diagnosis.
Coding tip
Verify that the chart explicitly links coronavirus to the secondary condition before assigning B97.2.
