The ICD-10-CM code for unspecified infectious disease is B99.9. The full clinical description is "Unspecified infectious disease". B99.9 is a billable/specific code that can be used on insurance claims and medical billing.

What does ICD-10 code B99.9 mean?

ICD-10-CM code B99.9 represents “Unspecified infectious disease”. It is classified under Chapter 1: Certain Infectious and Parasitic Diseases and is a billable/specific code that can be used on a claim.

Is B99.9 a billable code?

Yes, B99.9 is a billable/specific ICD-10-CM code and can be used to indicate a diagnosis on a medical claim.

What chapter is B99.9 in?

B99.9 is in Chapter 1: Certain Infectious and Parasitic Diseases (codes A00-B99).

What codes cannot be used with B99.9?

B99.9 has Excludes1 notes indicating codes that cannot be used together with it, including: certain localized infections - see body system-related chapters.

Are additional codes required with B99.9?

Yes, when using B99.9, also report: resistance to antimicrobial drugs (Z16.-).

What SNOMED CT codes does B99.9 map to?

B99.9 maps to 536 SNOMED CT concepts: 28637003, 36689008, 128070006, 12435008, 429562001, and 531 more. SNOMED CT is a clinical terminology used in electronic health records.

What are the UMLS CUIs for B99.9?

B99.9 is linked to 1 UMLS Concept Unique Identifier: C2833828. The UMLS (Unified Medical Language System) integrates multiple biomedical vocabularies maintained by the U.S. National Library of Medicine.

How does B99.9 relate to ICF functioning codes?

ICF (International Classification of Functioning, Disability and Health) codes describe how conditions like unspecified infectious disease affect a person's functioning — body functions, activities, participation, and environmental factors. AutoICD provides ICF Core Sets for 12+ conditions and can map clinical text to ICF categories automatically. Browse the ICF directory to explore functioning codes.

What is the ICD-11 equivalent of B99.9?

There is no direct ICD-11 mapping available for B99.9 in the WHO crosswalk tables. This may mean the concept is classified differently in ICD-11. Use the ICD-10 to ICD-11 converter to search for related codes.
