E72.04

E72.04 — Cystinosis

Billable / specific codeICD-10-CM

E72.04 is a billable, specific ICD-10-CM code for cystinosis. 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.

Fanconi (-de Toni) (-Debré) syndrome without cystinosis (E72.09)

Other codes that can never be billed with E72.04

These codes carry an Excludes1 note pointing at E72.04. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading E72.04 alone.

N16Renal tubulo-interstitial disorders in diseases classified elsewhere
E72.1Disorders of sulfur-bearing amino-acid metabolism

Risk adjustment

E72.04 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.

Coders do not find codes by browsing the tabular list — they look them up in the alphabetic index, under the word the physician wrote. These are the index entries that lead here, so you can see which chart wordings map to E72.04.
