ICD10 code of Mastocytosis and MCAS and ICD9 code

Mastocytosis is a rare disorder characterized by an excessive number of mast cells accumulating in various tissues and organs throughout the body. The International Classification of Diseases, 10th Revision (ICD-10), provides specific codes to identify this condition. The ICD-10 code for mastocytosis is C96.2. This code is used to classify and track cases of mastocytosis within healthcare and medical systems.

On the other hand, Mast Cell Activation Syndrome (MCAS) is a condition where mast cells are excessively activated, leading to a range of symptoms. Unlike mastocytosis, MCAS does not involve an increased number of mast cells. Unfortunately, MCAS does not have a specific ICD-10 code dedicated to it. Instead, physicians often use more general codes, such as T78.40 (Unspecified adverse effect of drug or medicament) or R53.83 (Other fatigue), to indicate MCAS-related symptoms.

Regarding the older ICD-9 coding system, the ICD-9 code for mastocytosis is 757.33. However, it's important to note that ICD-9 codes are no longer in use as ICD-10 has replaced it as the standard coding system.

Remember, it's always advisable to consult with a qualified healthcare professional for accurate diagnosis, treatment, and coding information related to specific medical conditions.
