Q41 — Congenital absence, atresia and stenosis of small intestine
Q41 is a non-billable header ICD-10-CM code for congenital absence, atresia and stenosis of small intestine. It cannot be billed on its own: choose one of the more specific child codes below.
Excludes1 — never code together
These conditions cannot occur together. Billing both on the same encounter is a denial.
Includes
Conditions this code covers.
- congenital obstruction, occlusion or stricture of small intestine or intestine NOS
Other codes that can never be billed with Q41
These codes carry an Excludes1 note pointing at Q41. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading Q41 alone.
Risk adjustment
Q41 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 history
Q41 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.

Questions about Q41
- Is Q41 a billable ICD-10-CM code?
- No. Q41 is a non-billable header code. Code to a higher level of specificity using one of its child codes.
- Where does Q41 sit in the tabular list?
- Congenital malformations, deformations and chromosomal abnormalities (Q00-QA0), in the block Other congenital malformations of the digestive system (Q38-Q45).
- What cannot be coded together with Q41?
- Q41 carries Excludes1 notes, which means the conditions they list can never be coded together with it on the same encounter.
