E00.2 — Congenital iodine-deficiency syndrome, mixed type
E00.2 is a billable, specific ICD-10-CM code for congenital iodine-deficiency syndrome, mixed type. It is valid for submission on a claim.
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Endemic cretinism, mixed type
Excludes1 inherited from the categories above E00.2
These are not written on E00.2, but they bind it: a note on a category applies to every code beneath it. Billing E00.2 with anything listed here is a denial.
Other codes that can never be billed with E00.2
These codes carry an Excludes1 note pointing at E00.2. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading E00.2 alone.
- E01Iodine-deficiency related thyroid disorders and allied conditions
Risk adjustment
E00.2 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
E00.2 is named in 2 Medicare coverage policies — 2 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
- A57326Billing and Coding: Electrocardiograms
- A57361Billing and Coding: Monitored Anesthesia Care
How E00.2 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 E00.2.
