What is ICD-10 code K50.014?

K50.014 is the ICD-10-CM diagnosis code for Crohn's disease of small intestine with abscess. Crohn's disease of the small intestine with a localized collection of pus (abscess) as a complication. It belongs to the ICD-10-CM chapter for diseases of the digestive system (k00-k95). K50.014 is a billable code, meaning it can be reported on a claim as a primary or secondary diagnosis when supported by documentation. K50.014 is part of the FY2026 ICD-10-CM code set published by the CMS National Center for Health Statistics and used on Medicare, Medicaid, and commercial claims in the United States.

Yes. K50.014 is a billable ICD-10-CM code that can be reported on professional and institutional claims as a primary or secondary diagnosis when the provider documentation supports the specific condition described. Billable codes in ICD-10-CM are coded to the highest level of specificity available for the documented diagnosis. K50.014 is current for fiscal year 2026 and remains in the active CMS ICD-10-CM code set published by the National Center for Health Statistics.

Which HCC does K50.014 map to under V28?

K50.014 maps to CMS-HCC V28 HCC 80 (Crohn's Disease (Regional Enteritis)). The category numbers, labels, and conditions come from the CMS-HCC V28 model file for payment year 2026.

Buddy Documentation Tip

Provider documentation of Crohn's disease of the small intestine with abscess formation

Imaging confirmation of abscess (CT scan with contrast is preferred)

Location and size of abscess documented

Drainage procedure documentation if performed (percutaneous vs. surgical)

Audit Caution

HCC Buddy guidance

Coding the abscess separately (K63.0) instead of using the Crohn's-specific combination code

Confusing abscess with fistula — they are different complications although they frequently coexist

Not confirming the abscess is related to Crohn's disease versus an independent intra-abdominal abscess

Failing to capture both abscess and fistula if they coexist (may need additional codes)

Common Mistakes

HCC Buddy guidance

K50.00 — Crohn's disease of small intestine without complications: no abscess present

K50.013 — Crohn's disease of small intestine with fistula: fistula (tract) vs. abscess (pus collection)

K50.114 — Crohn's disease of large intestine with abscess: large intestine location

K50.814 — Crohn's disease of both small and large intestine with abscess: both sites

Is K50.014 an HCC code?

Yes. K50.014 (Crohn's disease of small intestine with abscess) maps to HCC 80, Crohn's Disease (Regional Enteritis) under the CMS-HCC V28 risk adjustment model, with a source-labeled community non-dual aged reference coefficient of 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: K50.014 is billable and maps to V28 HCC 80, Crohn's Disease (Regional Enteritis). Open it in the Code Book for the tabular path, RAF, and MEAT checklist.

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 Criteria for K50.014

For K50.014 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 K50.014 during that encounter, not just copy-forwarded from a problem list.

What This Code Means

K50.014 is the ICD-10-CM diagnosis code for crohn's disease of small intestine with abscess. Crohn's disease of the small intestine with a localized collection of pus (abscess) as a complication. K50.014 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, K50.014 maps to Crohn's Disease (Regional Enteritis) (HCC 80) with a source-labeled community, non-dual, aged reference coefficient of 0.550. No V24 mapping is shown for K50.014; use the applicable model and payment year when reviewing the V28 mapping. 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. 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.

Abscess formation indicates a more severe disease state requiring intervention. Because K50.014 maps to an HCC category, the provider's documentation must satisfy MEAT criteria (Monitor, Evaluate, Assess, or Treat) before the diagnosis is used for risk adjustment. 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 K50.014 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.

Coding Tips

•Abscess formation indicates a more severe disease state requiring intervention
•Document the location of the abscess and any drainage procedures performed

Clinical Significance

Crohn's disease of the small intestine with abscess indicates a severe infectious complication where chronic inflammation leads to walled-off pus collections in the mesentery, abdominal wall, or peritoneal cavity. Abscesses in Crohn's disease often require percutaneous drainage or surgical intervention alongside antibiotic therapy. This complication may indicate disease progression or treatment failure.

Documentation Requirements

✓Provider documentation of Crohn's disease of the small intestine with abscess formation
✓Imaging confirmation of abscess (CT scan with contrast is preferred)
✓Location and size of abscess documented
✓Drainage procedure documentation if performed (percutaneous vs. surgical)
✓Antibiotic therapy and follow-up imaging plan
✓Assessment of whether the abscess is related to fistulizing disease
