Multiple sclerosis ICD-10 code
The ICD-10-CM code for multiple sclerosis is G35 — multiple sclerosis. It is a header code, so you must code to a higher level of specificity. There are 14 related codes, and which one you use depends on what the documentation supports.
Also written as ms.
The mistake coders make here
G35 is a single code with no subdivisions — there is nothing to choose. Code the manifestations separately if they are documented and clinically significant.
