ICD10 code of Hereditary Angioedema and ICD9 code

Hereditary angioedema (HAE) is a rare genetic disorder characterized by recurrent episodes of swelling in various body parts, including the skin, gastrointestinal tract, and airway. The ICD-10 code for hereditary angioedema is D84.1. This code falls under the "Other immunodeficiencies" category in the ICD-10 classification system.

In the previous ICD-9 coding system, hereditary angioedema was classified under the code 277.6. This code represented "Other deficiencies of circulating enzymes," which encompassed various enzymatic deficiencies, including HAE. However, it is important to note that the ICD-9 code system is no longer in use as it has been replaced by the more comprehensive ICD-10 coding system.

The ICD-10 code D84.1 provides a more specific classification for hereditary angioedema, allowing healthcare professionals to accurately identify and document cases of this condition. Accurate coding helps in tracking the prevalence and incidence of HAE, facilitating research, and ensuring appropriate reimbursement for medical services provided.

It is worth mentioning that the ICD-10 coding system is continually updated to reflect advancements in medical knowledge and terminology. Therefore, it is always important for healthcare professionals to consult the most recent version of the ICD-10 coding manual to ensure accurate coding and billing practices.

In conclusion, the ICD-10 code for hereditary angioedema is D84.1, while the obsolete ICD-9 code was 277.6. These codes are used to classify and identify cases of hereditary angioedema for medical documentation, research, and reimbursement purposes.
