B90-B94
2020 ICD-10-CM Range B90-B94
Sequelae of infectious and parasitic diseases
Code First
- condition resulting from (sequela) the infectious or parasitic disease
Note
- Categories B90-B94 are to be used to indicate conditions in categories A00-B89 as the cause of sequelae, which are themselves classified elsewhere. The 'sequelae' include conditions specified as such; they also include residuals of diseases classifiable to the above categories if there is evidence that the disease itself is no longer present. Codes from these categories are not to be used for chronic infections. Code chronic current infections to active infectious disease as appropriate.
