E83.820 — Generalized arterial calcification of infancy with unspecified genetic causality
E83.820 is a billable, specific ICD-10-CM code for generalized arterial calcification of infancy with unspecified genetic causality. It is valid for submission on a claim.
Code also
Both codes may be needed to describe the encounter fully. Sequencing depends on the reason for the visit.
Excludes1 inherited from the categories above E83.820
These are not written on E83.820, but they bind it: a note on a category applies to every code beneath it. Billing E83.820 with anything listed here is a denial.
Other codes that can never be billed with E83.820
These codes carry an Excludes1 note pointing at E83.820. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading E83.820 alone.
Risk adjustment
E83.820 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.
How E83.820 is indexed
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 E83.820.

Questions about E83.820
- Is E83.820 a billable ICD-10-CM code?
- Yes. E83.820 is a billable, specific ICD-10-CM code and is valid for submission on a claim.
- Where does E83.820 sit in the tabular list?
- Endocrine, nutritional and metabolic diseases (E00-E89), in the block Metabolic disorders (E70-E88).
- What cannot be coded together with E83.820?
