Is K50.912 an HCC code?
Yes. K50.912 (Crohn's disease, unspecified, with intestinal obstruction) maps to HCC 78, Intestinal Obstruction/Perforation and HCC 80, Crohn's Disease (Regional Enteritis) under the CMS-HCC V28 risk adjustment model, with source-labeled community non-dual aged reference coefficients HCC 78 0.326 and HCC 80 0.550. Source-labeled code-level coefficients are references, not member totals. Actual contribution depends on complete member context, hierarchy and cleanup rules, interactions, and model year. HCC Buddy's RAF Calculator supports CMS-HCC V28 PY2026 and shows no score unless every required source and calculation check passes. It is billable for payment year 2026.
Coder answer: K50.912 is billable and maps to V28 HCC 78, Intestinal Obstruction/Perforation and HCC 80, Crohn's Disease (Regional Enteritis). Open it in the Code Book for the tabular path, RAF, and MEAT checklist.

HCC Category Mapping
These are source-labeled model coefficients, not member totals. A category may still be removed by hierarchy or model cleanup rules. 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 context, hierarchy and cleanup rules, interactions, and the model year used by the payer. V28 is the CMS-HCC model phased in over payment years 2024–2026; V24 remains available for historical review.

MEAT review for K50.912
For K50.912, confirm that the documentation supports the diagnosis and meets the applicable coding, encounter, program and payer requirements. MEAT (Monitor, Evaluate, Assess, or Treat) is a review mnemonic, not a universal CMS coding rule.
- 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

What This Code Means
K50.912 is the ICD-10-CM diagnosis code for crohn's disease, unspecified, with intestinal obstruction. Crohn's disease of unspecified location with intestinal obstruction, a blockage preventing normal food passage. K50.912 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, K50.912 maps to Intestinal Obstruction/Perforation (HCC 78) with a source-labeled community, non-dual, aged reference coefficient of 0.326. No V24 mapping is shown for K50.912; use the applicable model and payment year when reviewing the V28 mapping. For CY2026 non-PACE Medicare Advantage, CMS uses 100% of the 2024 CMS-HCC model (V28). PACE uses a separate model blend. Source-labeled code-level coefficients are references, not member totals. Actual contribution depends on complete member context, hierarchy and cleanup rules, interactions, and model year. HCC Buddy's RAF Calculator supports CMS-HCC V28 PY2026 and shows no score unless every required source and calculation check passes.
Document whether the obstruction is partial or complete, as this may affect clinical management. For K50.912, confirm that the documentation supports the diagnosis and meets the applicable coding, encounter, program and payer requirements. MEAT (Monitor, Evaluate, Assess, or Treat) is a review mnemonic, not a universal CMS coding rule. 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, source-labeled coefficient references, and MEAT documentation criteria for K50.912 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Document whether the obstruction is partial or complete, as this may affect clinical management
- •Verify that the obstruction is related to Crohn's disease and not a separate mechanical cause
Clinical Significance
Crohn's disease, unspecified, with intestinal obstruction combines unspecified disease location with a serious obstructive complication. The obstruction itself may help localize the disease, as small bowel obstruction is more common in Crohn's. This complication requires urgent management and the unspecified site should prompt review of imaging studies that would reveal both the obstruction and disease location.
Documentation Requirements
- ✓Provider documentation of Crohn's disease with intestinal obstruction
- ✓Imaging evidence confirming obstruction
- ✓Documentation that the disease site could not be determined
- ✓Partial vs. complete obstruction specification
- ✓Treatment approach and outcome
Commonly Confused Codes
- •K50.012: Crohn's disease of small intestine with intestinal obstruction: small intestine specified
- •K50.112: Crohn's disease of large intestine with intestinal obstruction: large intestine specified
- •K50.812: Crohn's disease of both sites with intestinal obstruction: both sites specified
- •K50.90: Crohn's disease, unspecified, without complications: no obstruction
- •K56.60: Unspecified intestinal obstruction: not attributed to Crohn's disease
