I32 — Pericarditis in diseases classified elsewhere

Billable / specific codeICD-10-CM

I32 is a billable, specific ICD-10-CM code for pericarditis 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.

pericarditis (in):
coxsackie (virus) (B33.23)
gonococcal (A54.83)
meningococcal (A39.53)
rheumatoid (arthritis) (M05.31)
syphilitic (A52.06)
systemic lupus erythematosus (M32.12)
tuberculosis (A18.84)

Code first

The underlying condition must be sequenced before this code.

Risk adjustment

I32 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

I32 is named in 18 Medicare coverage policies — 18 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
