This note appears immediately under a three character code title to further define, or give examples of, the content of the category.
Code First
Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions, the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists, there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation.
Use Additional Code
The “use additional code” indicates that a secondary code could be used to further specify the patient’s condition. This note is not mandatory and is only used if enough information is available to assign an additional code.
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Patient EducationClinical
HIV
HIV stands for human immunodeficiency virus. HIV harms your immune system by destroying a type of white blood cell that helps your body fight infection. This puts you at risk for other infections and diseases.

Questions About B20Overview
Is B20 (Human immunodeficiency virus [HIV] disease) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report human immunodeficiency virus [HIV] disease on HIPAA-covered claims from October 1, 2025 through September 30, 2026.
What MS-DRG does B20 group to?
When human immunodeficiency virus [HIV] disease is the principal diagnosis on an inpatient stay, it groups to MS-DRG 969, 970, 974, 975, 976, 977, with relative weights from 0.8945 to 6.1213 depending on complications. Higher weights mean higher Medicare reimbursement.
What is the ICD-9 equivalent of B20?
Under the General Equivalence Mappings, human immunodeficiency virus [HIV] disease converts to ICD-9-CM 042 (human immuno virus dis). The mapping is a direct match.
Footnotes
[1] Chronic - a chronic condition code indicates a condition lasting 12 months or longer and its effect on the patient based on one or both of the following criteria:
- The condition results in the need for ongoing intervention with medical products,treatment, services, and special equipment
- The condition places limitations on self-care, independent living, and social interactions.
