B90-B94 — Sequelae of infectious and parasitic diseases
ICD-10-CM codes B90-B94 cover sequelae of infectious and parasitic diseases, within certain infectious and parasitic diseases. The block holds 14 codes across 4 categories, of which 12 are billable and 2 are header codes that cannot be submitted on a claim.
Code first
The underlying condition must be sequenced before this code.
- condition resulting from (sequela) the infectious or parasitic disease
Notes
Additional guidance from the ICD-10-CM tabular list.
- 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.
What else to watch in B90-B94
- 5 codes are named in Medicare coverage policies. An LCD or NCD lists them as supporting medical necessity, or explicitly as not supporting it. Which applies depends on the MAC for your state.
