M36.8 — Systemic disorders of connective tissue in other diseases classified elsewhere

Billable / specific codeICD-10-CM

M36.8 is a billable, specific ICD-10-CM code for systemic disorders of connective tissue in other diseases classified elsewhere. It is valid for submission on a claim.

Code first

The underlying condition must be sequenced before this code.

underlying disease, such as:
alkaptonuria (E70.29)
hypogammaglobulinemia (D80.-)
ochronosis (E70.29)

Excludes2 inherited from the categories above M36.8

Also inherited, and the opposite of Excludes1: these conditions are not part of M36.8, but a patient can have both, so you may code both.

arthropathies in diseases classified elsewhere (M14.-)

Risk adjustment

M36.8 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Medicare coverage

M36.8 is named in 8 Medicare coverage policies — 1 listing it as supporting medical necessity, and 7 listing it as NOT covered. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
