Q89.01

Q89.01 — Asplenia (congenital)

Billable / specific codeICD-10-CMPOA exempt

Q89.01 is a billable, specific ICD-10-CM code for asplenia (congenital). It is valid for submission on a claim.

Excludes1 inherited from the categories above Q89.01

These are not written on Q89.01, but they bind it: a note on a category applies to every code beneath it. Billing Q89.01 with anything listed here is a denial.

Written on Q89.0 — Congenital absence and malformations of spleen

isomerism of atrial appendages (with asplenia or polysplenia) (Q20.6)

Other codes that can never be billed with Q89.01

These codes carry an Excludes1 note pointing at Q89.01. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading Q89.01 alone.

D73.0Hyposplenism

Risk adjustment

Q89.01 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

Q89.01 is named in 5 Medicare coverage policies — 5 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
