Excludes2 — not included here, but may coexist

The excluded condition is not part of this code, but a patient can have both. You may code both.

hyperornithinemia (E72.4)
ornithinemia (E72.4)

Other codes that can never be billed with H31.2

H31.2 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.

Code to one of these instead H31.2
