I52 — Other heart disorders in diseases classified elsewhere

Billable / specific codeICD-10-CM

I52 is a billable, specific ICD-10-CM code for other heart disorders 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.

heart disease (in):
gonococcal infection (A54.83)
meningococcal infection (A39.50)
rheumatoid arthritis (M05.31)
syphilis (A52.06)

Code first

The underlying condition must be sequenced before this code.

underlying disease, such as:
congenital syphilis (A50.5)
mucopolysaccharidosis (E76.3)
schistosomiasis (B65.0-B65.9)

Risk adjustment

I52 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

I52 is named in 10 Medicare coverage policies — 10 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
