What is ICD-10 code E83.119?

E83.119 is the ICD-10-CM diagnosis code for Hemochromatosis, unspecified. Iron overload in the body when the specific type or cause is not documented or determined. It belongs to the ICD-10-CM chapter for endocrine, nutritional and metabolic diseases (e00-e89). E83.119 is a billable code, meaning it can be reported on a claim as a primary or secondary diagnosis when supported by documentation. E83.119 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. E83.119 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. E83.119 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 E83.119 map to under V28?

E83.119 has no payable CMS-HCC V28 mapping in the final FY2026 CMS file.

What RAF reference is published for E83.119?

E83.119 has no V28 reference coefficient because the final FY2026 source verifies no payable V28 mapping.

What is the V28 vs V24 difference for E83.119?

E83.119 has verified no payable V28 mapping in the final FY2026 source. Select a historical effective period before making any V24 comparison.

What documentation supports E83.119?

This is a less specific code; query the provider if the type of hemochromatosis can be determined Use only when documentation does not specify hereditary or secondary causes E83.119 is not a CMS-HCC V28 payment code in the verified current source, so MEAT is not the payment hook. Documentation still has to support the diagnosis if you report it.

Audit Caution

HCC Buddy guidance

Accepting the unspecified code when documentation actually supports hereditary type — always review for genetic testing results or family history

Missing HCC capture opportunity by not querying provider to specify hereditary vs. other type

Using this code when 'elevated ferritin' or 'iron overload' is documented without a formal hemochromatosis diagnosis

Not recognizing that clarification between hereditary and other forms directly impacts risk adjustment

Common Mistakes

HCC Buddy guidance

E83.110 — Hereditary hemochromatosis: preferred code when hereditary type is confirmed; carries HCC mapping

E83.118 — Other hemochromatosis: use when secondary or non-hereditary type is specified

E83.10 — Disorder of iron metabolism, unspecified: even less specific; avoid if hemochromatosis is documented

R79.89 — Other specified abnormal findings of blood chemistry: do not use for elevated ferritin when hemochromatosis is diagnosed

Is E83.119 an HCC code?

E83.119 is not in the CMS-HCC V28 or V24 community payment model. E83.119 has a separate mapping under the Part D RxHCC model (HCC 43 (Pituitary, Adrenal Gland, and Other Endocrine and Metabolic Disorders)); the applicable result needs member context.

Not separately weighted

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 E83.119

For E83.119, 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

E83.119 is the ICD-10-CM diagnosis code for hemochromatosis, unspecified. Iron overload in the body when the specific type or cause is not documented or determined. E83.119 sits in the ICD-10-CM chapter for endocrine, nutritional and metabolic diseases (e00-e89), within the section covering metabolic disorders (e70-e88).

E83.119 has no mapping under the CMS-HCC V28 or V24 community payment models. E83.119 has a separate mapping under the Part D RxHCC model (HCC 43 (Pituitary, Adrenal Gland, and Other Endocrine and Metabolic Disorders)); the applicable result needs member context. Do not assign V28 risk adjustment value from this page; verify the applicable model and payment year before using this code for risk adjustment.

This is a less specific code; query the provider if the type of hemochromatosis can be determined.

HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for E83.119 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.

Coding Tips

•This is a less specific code; query the provider if the type of hemochromatosis can be determined
•Use only when documentation does not specify hereditary or secondary causes

Clinical Significance

Hemochromatosis, unspecified is used when iron overload is confirmed but the specific type (hereditary vs. acquired) has not been determined. This code should prompt a query to the provider for clarification, as hereditary hemochromatosis maps to an HCC while this unspecified code does not.

Documentation Requirements

✓Diagnosis of hemochromatosis by the treating provider
✓Laboratory evidence of iron overload (elevated ferritin, transferrin saturation)
✓Reason the type cannot be specified (pending genetic testing, new diagnosis workup)
✓Treatment plan or referral for further evaluation
✓Query attempt to provider for hereditary vs. acquired specification
