M36 — Systemic disorders of connective tissue in diseases classified elsewhere
Is M36 billable?
No — M36 is a non-billable header code. M36 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 6 billable codes beneath M36.

Excludes2 — not included here
The conditions below are not part of M36, but a patient may have both at the same time. When documentation supports it, M36 and the excluded code may both be reported.
- arthropathies in diseases classified elsewhere (M14.-)
Excludes1 — never code together — inherited from M30-M36
The conditions below can never be reported together with M36 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- autoimmune disease, single organ or single cell-type -code to relevant condition category
Excludes2 — not included here — inherited from Chapter 13
The conditions below are not part of M36, but a patient may have both at the same time. When documentation supports it, M36 and the excluded code may both be reported.

- certain infectious and parasitic diseases (A00-B99)

How long has M36 existed?
M36 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
