K50.01 — Crohn's disease of small intestine with complications

Non-billable headerICD-10-CM

Excludes1 inherited from the categories above K50.01

These are not written on K50.01, but they bind it: a note on a category applies to every code beneath it. Billing K50.01 with anything listed here is a denial.

Written on K50.0 — Crohn's disease of small intestine

Crohn's disease of both small and large intestine (K50.8-)

Written on K50 — Crohn's disease [regional enteritis]

ulcerative colitis (K51.-)

Other codes that can never be billed with K50.01

These codes carry an Excludes1 note pointing at K50.01. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading K50.01 alone.

E55.0Rickets, active
K63.0Abscess of intestine
K63.2Fistula of intestine
K51Ulcerative colitis

Risk adjustment

K50.01 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.

Code history

K50.01 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
