Is E07.89 an HCC code?
E07.89 is not in the CMS-HCC V28 or V24 community payment model. E07.89 has a separate mapping under the Part D RxHCC model (HCC 44 (Thyroid Disorders)); the applicable result needs member context.

HCC Category Mapping
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 Criteria for E07.89
For E07.89 to 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 E07.89 during that encounter, not just copy-forwarded from a problem list.

What This Code Means
E07.89 is the ICD-10-CM diagnosis code for other specified disorders of thyroid. Other specified thyroid disorders not classified elsewhere, including various thyroid dysfunctions and abnormalities. E07.89 sits in the ICD-10-CM chapter for endocrine, nutritional and metabolic diseases (e00-e89), within the section covering disorders of thyroid gland (e00-e07).
E07.89 has no mapping under the CMS-HCC V28 or V24 community payment models. E07.89 has a separate mapping under the Part D RxHCC model (HCC 44 (Thyroid 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.
Use this code only when a more specific thyroid disorder code is not available.
HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for E07.89 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Use this code only when a more specific thyroid disorder code is not available
- •Clearly document the specific thyroid condition in the medical record for clarity
Clinical Significance
Other specified disorders of thyroid encompasses thyroid conditions not classified in more specific categories, including sick euthyroid syndrome (euthyroid sick syndrome/non-thyroidal illness syndrome), thyroid hormone resistance syndromes, and other rare thyroid functional abnormalities. Sick euthyroid syndrome is particularly common in hospitalized critically ill patients, where thyroid function tests are abnormal due to systemic illness rather than intrinsic thyroid disease. Accurate differentiation from true thyroid disease prevents unnecessary treatment.
Documentation Requirements
- ✓Document the specific thyroid disorder being classified, supporting laboratory values, and the clinical context distinguishing this from more common thyroid conditions.
- ✓For sick euthyroid syndrome, document the underlying systemic illness and note that abnormal thyroid tests are secondary rather than primary thyroid disease.
