Audit Caution

HCC Buddy guidance

Coding a perianal or perirectal abscess as K61 instead of K50.114 when it is related to Crohn's disease

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

Using the uncomplicated code when an abscess is documented

Not assessing for sepsis which would require additional coding

Is K50.114 an HCC code?

Yes. K50.114 (Crohn's disease of large 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: K50.114 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 review for K50.114

For K50.114, 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

K50.114 is the ICD-10-CM diagnosis code for crohn's disease of large intestine with abscess. Crohn's disease of the large intestine with a localized collection of pus (abscess) in or around the intestinal tissue. K50.114 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, K50.114 maps to Crohn's Disease (Regional Enteritis) (HCC 80) with a source-labeled community, non-dual, aged reference coefficient of 0.550. 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.

Confirm documentation specifies abscess as a complication; note the location if documented. For K50.114, 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 K50.114 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.

Coding Tips

•Confirm documentation specifies abscess as a complication; note the location if documented
•Abscesses may require additional intervention codes if drained or treated surgically

Clinical Significance

Crohn's disease of the large intestine with abscess is a severe infectious complication indicating pericolonic or pericolic pus collection. Abscesses in colonic Crohn's disease may present as perianal, mesenteric, or intra-abdominal collections requiring drainage and antibiotics. This complication often heralds underlying fistulizing disease and may necessitate surgical management.

Documentation Requirements

✓Provider documentation of Crohn's disease of the large intestine with abscess
✓Imaging confirmation of abscess with size and location documented
✓Drainage procedure documentation if performed
✓Antibiotic therapy prescribed
✓Assessment for concurrent fistulizing disease
✓Follow-up imaging plan to confirm resolution
