Is K50.112 an HCC code?
Yes. K50.112 (Crohn's disease of large intestine with intestinal obstruction) maps to Intestinal Obstruction/Perforation under the CMS-HCC V28 risk adjustment model (and Intestinal Obstruction/Perforation under V24), with a community non-dual aged RAF of 0.326. It is billable for payment year 2026.
Coder answer: K50.112 is billable and maps to V28 HCC 78, Intestinal Obstruction/Perforation. Open it in the Code Book for the tabular path, RAF, and MEAT checklist.

HCC Category Mapping
Each model's RAF is its CMS base weight for that model's standard population, so weights are not directly comparable across models: CMS-HCC V28 and V24 use Community, Non-Dual, Aged; ESRD uses the dialysis continuing-enrollee model; RxHCC is the Part D continuing-enrollee, non-low-income, aged weight (a larger scale than CMS-HCC). ACA/HHS has no single weight — it varies by metal level. Actual per-patient RAF contribution depends on member segment, interactions, and the model year used by the payer. V28 is the CMS-HCC model phased in over payment years 2024–2026; V24 remains in use during the transition and for historical data.

MEAT Criteria for K50.112
For K50.112 to count as a valid HCC diagnosis in a given encounter, the provider's documentation must show MEAT: Monitor, Evaluate, Assess, or Treat. A diagnosis from a prior year does not carry forward automatically, it has to be re-documented and supported each calendar year.
- MMonitor: signs, symptoms, disease progression, or lab trending documented in the note
- EEvaluate: test results, medication response, or physical findings reviewed by the provider
- AAssess: explicit mention in the assessment or plan with acknowledgment of status
- TTreat: medication, referral, procedure, therapy, or counseling tied to the diagnosis
Only one of M/E/A/T is required to support the code, but the documentation must be specific enough to show that the provider actually addressed K50.112 during that encounter, not just copy-forwarded from a problem list.

What This Code Means
K50.112 is the ICD-10-CM diagnosis code for crohn's disease of large intestine with intestinal obstruction. Crohn's disease affecting the large intestine with a blockage that prevents food and waste from passing through normally. K50.112 sits in the ICD-10-CM chapter for diseases of the digestive system (k00-k95), within the section covering noninfective enteritis and colitis (k50-k52).
Under the CMS-HCC V28 risk adjustment model, K50.112 maps to Intestinal Obstruction/Perforation (HCC 78) with a community, non-dual, aged base RAF weight of 0.326. Under the older V24 model, K50.112 mapped to the same category but with a base RAF weight of 0.219, V28 recalibrated weights across the entire model. V28 is the CMS-HCC risk adjustment model that reached 100% phase-in for payment year 2026, replacing V24 which was used during the PY2024–PY2025 transition.
Verify documentation specifies the large intestine (colon) location and confirms intestinal obstruction as a complication. Because K50.112 maps to a payment HCC, the provider's documentation must satisfy MEAT criteria (Monitor, Evaluate, Assess, or Treat) for the encounter to count toward the patient's Medicare Advantage risk adjustment score. When documentation is ambiguous, coders should issue a provider query rather than assume the highest-specificity variant.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for K50.112 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Verify documentation specifies the large intestine (colon) location and confirms intestinal obstruction as a complication
- •Do not use this code if obstruction is not documented; use K50.110 instead for uncomplicated disease
Clinical Significance
Crohn's disease of the large intestine with intestinal obstruction indicates stricturing disease in the colon causing bowel blockage. Colonic obstruction in Crohn's disease is less common than small bowel obstruction but carries significant clinical impact, potentially requiring emergency surgical intervention including colectomy. This complication reflects advanced or poorly controlled disease.
Documentation Requirements
- ✓Provider documentation of Crohn's disease of the large intestine with intestinal obstruction
- ✓Imaging confirmation of colonic obstruction (CT abdomen, abdominal X-ray)
- ✓Specification of partial vs. complete obstruction
- ✓Location of obstruction within the colon if documented
- ✓Clinical presentation (abdominal distension, obstipation, nausea/vomiting)
- ✓Treatment approach (conservative management vs. surgical intervention)
Commonly Confused Codes
- •K50.10: Crohn's disease of large intestine without complications: no obstruction present
- •K50.012: Crohn's disease of small intestine with intestinal obstruction: small intestine location
- •K50.812: Crohn's disease of both small and large intestine with intestinal obstruction: both sites
- •K56.60: Unspecified intestinal obstruction: not attributed to Crohn's disease
- •K50.113: Crohn's disease of large intestine with fistula: different complication type
