ICD10 code of Mixed Connective Tissue Disease (MCTD) and ICD9 code

The ICD-10 code for Mixed Connective Tissue Disease (MCTD) is M35.1. This code falls under the category of "Systemic involvement of connective tissue" in the ICD-10 coding system. MCTD is a rare autoimmune disorder characterized by a combination of symptoms from various connective tissue diseases such as systemic lupus erythematosus, scleroderma, and polymyositis. It is important to note that MCTD has overlapping features of these conditions, making it a distinct diagnosis.

In the previous ICD-9 coding system, MCTD was not specifically identified as a separate condition. Instead, it was typically coded as a combination of the individual connective tissue diseases present in the patient, depending on their predominant symptoms. This lack of a specific code for MCTD in ICD-9 made it challenging to accurately capture and identify cases of this condition.

Please consult with a healthcare professional or coding expert for accurate and up-to-date coding information.
