Last updated: FY2026 ICD-10-CM Apr update, Apr 1, 2026 through Sep 30, 2026. CMS-HCC V28 is 100% phased in for payment year 2026.
Is N99.530 an HCC code?
Yes. N99.530 maps to Complications of Specified Implanted Device or Graft under the V24 model but is not retained in V28.

RAF weights shown are the community, non-dual, aged base weights from the CMS risk adjustment model file. 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 N99.530
For N99.530to 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 N99.530 during that encounter, not just copy-forwarded from a problem list.

What This Code Means
N99.530 is the ICD-10-CM diagnosis code for hemorrhage of continent stoma of urinary tract. Bleeding from a surgically created urine drainage opening that controls urine flow and prevents leakage. N99.530 sits in the ICD-10-CM chapter for diseases of the genitourinary system (n00-n99), within the section covering intraoperative and postprocedural complications and disorders of genitourinary system, not elsewhere classified (n99).
Under the older CMS-HCC V24 model, N99.530 maps to Complications of Specified Implanted Device or Graft (HCC 176) with a community, non-dual, aged base RAF weight of 0.529. 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.
Distinguish between continent and incontinent stomas; continent stomas have sphincter control. Because N99.530 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 N99.530 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Distinguish between continent and incontinent stomas; continent stomas have sphincter control
- •Document the severity and source of hemorrhage for clinical context
Clinical Significance
Hemorrhage from a continent urinary stoma indicates a potentially serious complication that may compromise the stoma's continence mechanism. This bleeding requires careful evaluation to identify underlying causes and prevent functional deterioration of the carefully constructed continent system.
Documentation Requirements
- ✓Documentation of continent urinary stoma type and construction
- ✓Description of bleeding severity and characteristics
- ✓Duration and pattern of hemorrhagic episodes
- ✓Impact on continence mechanism
- ✓Associated symptoms or complications
- ✓Interventions to control bleeding
- ✓Assessment of stoma structural integrity
