B94 is a non-billable ICD-10-CM category code for sequelae of other and unspecified infectious and parasitic diseases, so it cannot be submitted on claims. Use a more specific code from this category instead, such as B94.0, B94.1, B94.2, and B94.8.

Specific Coding for Sequelae of other and unsp infectious and parasitic diseasesOverview

Non-specific codes like B94 require more characters. Use one of these billable codes instead:

  • Use B94.0 for Sequelae of trachoma

  • Use B94.1 for Sequelae of viral encephalitis

  • Use B94.2 for Sequelae of viral hepatitis

  • Use B94.8 for Sequelae of other specified infectious and parasitic diseases

  • Use B94.9 for Sequelae of unspecified infectious and parasitic disease

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to B94: its own notes plus those printed at block B90-B94 and Chapter 1. A note printed at a category, block or chapter applies to every code under it.

Includes

Further defines, or gives examples of, the content of the category.

From Chapter 1 (A00-B99) Certain infectious and parasitic diseases applies to 1,068 codes
  • diseases generally recognized as communicable or transmissible

Excludes2

Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.

From Chapter 1 (A00-B99) Certain infectious and parasitic diseases applies to 1,068 codes
  • carrier or suspected carrier of infectious disease (Z22.-)
  • certain localized infections - see body system-related chapters
  • infectious and parasitic diseases complicating pregnancy, childbirth and the puerperium (O98.-)
  • infectious and parasitic diseases specific to the perinatal period (P35-P39)
  • influenza and other acute respiratory infections (J00-J22)

Code First

The underlying condition named in the note is sequenced before this code.

From Block B90-B94 Sequelae of infectious and parasitic diseases applies to 12 codes
  • condition resulting from (sequela) the infectious or parasitic disease

Use Additional Code

Add a second code, after this one, to fully describe the condition.

From Chapter 1 (A00-B99) Certain infectious and parasitic diseases applies to 1,068 codes
  • code to identify resistance to antimicrobial drugs (Z16.-)

Notes

General instructions on how these codes are used.

From Block B90-B94 Sequelae of infectious and parasitic diseases applies to 12 codes
  • 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.

Infectious Diseases

Germs, or microbes, are found everywhere - in the air, soil, and water. There are also germs on your skin and in your body. Many of them are harmless, and some can even be helpful. But some of them can make you sick. Infectious diseases are diseases that are caused by germs.

  • What are the different types of germs that cause infectious diseases?
  • How can you get infectious diseases?
  • What are the symptoms of infectious diseases?
  • What are the treatments for infectious diseases?
  • Can infectious diseases be prevented?

Questions About B94Overview

What is the ICD-10 code for sequelae of other and unspecified infectious and parasitic diseases?

B94 is the ICD-10-CM category for sequelae of other and unspecified infectious and parasitic diseases, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is B94 a billable code?

No. This is a category header that groups the codes for sequelae of other and unspecified infectious and parasitic diseases, and headers cannot be submitted on claims. Claims for sequelae of other and unspecified infectious and parasitic diseases need a more specific code from this category, such as B94.0, B94.1, and B94.2.
