Histaminosis / Histamine Intolerance ICD10 code: T78.4
Histaminosis / Histamine Intolerance ICD9 code: 995.3
Histaminosis, also known as histamine intolerance, is a condition characterized by the body's inability to properly break down and metabolize histamine, a compound involved in various physiological processes. This leads to an accumulation of histamine in the body, causing a range of symptoms such as headaches, gastrointestinal disturbances, skin rashes, and respiratory issues.
In terms of coding, the International Classification of Diseases, 10th Revision (ICD-10) provides a specific code for histaminosis. The appropriate ICD-10 code for this condition is T78.3. This code falls under the chapter titled "Adverse effects, not elsewhere classified," and specifically refers to "unspecified adverse effect of other drugs, medicaments, and biological substances." Histaminosis is classified under this category as it involves an adverse reaction to histamine, a biological substance.
On the other hand, the International Classification of Diseases, 9th Revision (ICD-9) does not have a specific code for histaminosis or histamine intolerance. However, it is important to note that ICD-9 codes are outdated and no longer in use as of October 1, 2015. The healthcare industry has transitioned to ICD-10 codes, which provide more detailed and accurate classification of diseases and conditions.
In conclusion, the ICD-10 code for histaminosis or histamine intolerance is T78.3, while there is no specific ICD-9 code for this condition. It is important for healthcare professionals to use the most up-to-date coding system, which is currently ICD-10, to accurately document and classify patients' conditions for proper diagnosis, treatment, and reimbursement purposes.
