E83.30 — Disorder of phosphorus metabolism, unspecified
E83.30 is a billable, specific ICD-10-CM code for disorder of phosphorus metabolism, unspecified. It is valid for submission on a claim.
Excludes1 inherited from the categories above E83.30
These are not written on E83.30, but they bind it: a note on a category applies to every code beneath it. Billing E83.30 with anything listed here is a denial.
Written on E83.3 — Disorders of phosphorus metabolism and phosphatases
Excludes2 inherited from the categories above E83.30
Also inherited, and the opposite of Excludes1: these conditions are not part of E83.30, but a patient can have both, so you may code both.
Other codes that can never be billed with E83.30
These codes carry an Excludes1 note pointing at E83.30. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading E83.30 alone.
Risk adjustment
E83.30 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
E83.30 is named in 13 Medicare coverage policies — 13 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
