E83.824
Billable / SpecificICD-10-CMOfficial ICD-10-CMCodebook guidanceABCC6 deficiency causing pseudoxanthoma elasticum
This is a rare genetic disorder where a defective gene (ABCC6) causes the body to deposit calcium and other minerals in elastic tissues, leading to premature aging of the skin, eyes, and blood vessels. People with this condition develop yellowish bumps on their skin and may experience vision problems and heart complications.

Buddy Documentation Tip
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 E83.824 an HCC code?
E83.824 is not in the CMS-HCC V28 or V24 community payment model, but it does map to Other Significant Endocrine and Metabolic Disorders under the CMS-HCC ESRD model and Other Significant Endocrine and Metabolic Disorders under the Part D RxHCC model.
HCC Category Mapping
Each model's RAF is its CMS base weight for that model's standard population, so 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 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 E83.824
For E83.824to 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 E83.824 during that encounter, not just copy-forwarded from a problem list.

What This Code Means
E83.824 is the ICD-10-CM diagnosis code for abcc6 deficiency causing pseudoxanthoma elasticum. This is a rare genetic disorder where a defective gene (ABCC6) causes the body to deposit calcium and other minerals in elastic tissues, leading to premature aging of the skin, eyes, and blood vessels. People with this condition develop yellowish bumps on their skin and may experience vision problems and heart complications. E83.824 sits in the ICD-10-CM chapter for endocrine, nutritional and metabolic diseases (e00-e89), within the section covering metabolic disorders (e70-e88).
E83.824 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.
This code requires documentation of the genetic deficiency (ABCC6) and confirmation of pseudoxanthoma elasticum diagnosis; genetic testing results should be referenced in the medical record.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for E83.824 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •This code requires documentation of the genetic deficiency (ABCC6) and confirmation of pseudoxanthoma elasticum diagnosis; genetic testing results should be referenced in the medical record
- •Code E83.824 is specific to ABCC6 deficiency; do not use if the pseudoxanthoma elasticum is due to other causes, and consider coding associated manifestations (skin, ocular, cardiovascular) separately if they are clinically significant
