What is ICD-10 code Y62.2?

Y62.2 is the ICD-10-CM diagnosis code for Failure of sterile precautions during kidney dialysis and other perfusion. A kidney dialysis or other perfusion procedure where sterile precautions were not properly followed. It belongs to the ICD-10-CM chapter for external causes of morbidity (v00-y99). Y62.2 is a billable code, meaning it can be reported on a claim as a primary or secondary diagnosis when supported by documentation. Y62.2 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. Y62.2 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. Y62.2 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.

What is the V28 vs V24 difference for Y62.2?

CMS phased in the V28 risk adjustment model over payment years 2024 (33%), 2025 (67%), and 2026 (100%), replacing V24. V28 consolidates HCC categories, removes some lower-acuity conditions, and recalibrates RAF weights across the entire model. Y62.2 was a payment HCC under V24 (Dialysis Status) but the V28 recalibration removed it from the risk adjustment model. Both models can still appear in legacy data and in payer-specific lookback periods.

What should coders know when reporting Y62.2?

Specify the type of perfusion procedure in the documentation Link to any infection or complication codes that resulted from the breach in sterility Because Y62.2 maps to a payment HCC, the documentation must also satisfy MEAT criteria (Monitor, Evaluate, Assess, or Treat) for the encounter to count toward the patient's risk adjustment score.

Is Y62.2 an HCC code?

Yes. Y62.2 maps to Dialysis Status 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 Y62.2

For Y62.2to 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 Y62.2 during that encounter, not just copy-forwarded from a problem list.

What This Code Means

Y62.2 is the ICD-10-CM diagnosis code for failure of sterile precautions during kidney dialysis and other perfusion. A kidney dialysis or other perfusion procedure where sterile precautions were not properly followed. Y62.2 sits in the ICD-10-CM chapter for external causes of morbidity (v00-y99), within the section covering misadventures to patients during surgical and medical care (y62-y69).

Under the older CMS-HCC V24 model, Y62.2 maps to Dialysis Status (HCC 134) with a community, non-dual, aged base RAF weight of 0.452. 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.

Specify the type of perfusion procedure in the documentation. Because Y62.2 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 Y62.2 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.

Coding Tips

•Specify the type of perfusion procedure in the documentation
•Link to any infection or complication codes that resulted from the breach in sterility

Clinical Significance

Failure of sterile precautions during kidney dialysis represents a serious breach in infection control that puts ESRD patients at high risk for bloodstream infections, hepatitis, and other serious complications. This code indicates a quality of care issue requiring investigation and corrective action.

Documentation Requirements

✓Documentation of dialysis procedure being performed
✓Clear evidence of sterile precaution failure or breach
✓Description of specific sterile technique violation
✓Assessment of patient risk or actual adverse outcomes
✓Infection control measures taken post-incident
✓Quality improvement or incident reporting documentation
