I41 — Myocarditis in diseases classified elsewhere

Billable / specific codeICD-10-CM

I41 is a billable, specific ICD-10-CM code for myocarditis in diseases classified elsewhere. It is valid for submission on a claim.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

myocarditis (in):
Chagas' disease (chronic) (B57.2)
acute (B57.0)
coxsackie (virus) infection (B33.22)
diphtheritic (A36.81)
gonococcal (A54.83)
influenzal (J09.X9, J10.82, J11.82)
meningococcal (A39.52)
mumps (B26.82)
rheumatoid arthritis (M05.31)
sarcoid (D86.85)
syphilis (A52.06)
toxoplasmosis (B58.81)
tuberculous (A18.84)

Code first

The underlying condition must be sequenced before this code.

underlying disease, such as:
typhus (A75.0-A75.9)

Risk adjustment

I41 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

I41 is named in 15 Medicare coverage policies — 15 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
