Is D3A.098 an HCC code?
Yes. D3A.098 (Benign carcinoid tumors of other sites) maps to HCC 22, Bladder, Colorectal, and Other Cancers under the CMS-HCC V28 risk adjustment model, with a source-labeled community non-dual aged reference coefficient of 0.363. Source-labeled code-level coefficients are references, not member totals. Actual contribution depends on complete member context, hierarchy and cleanup rules, interactions, and model year. HCC Buddy's RAF Calculator supports CMS-HCC V28 PY2026 and shows no score unless every required source and calculation check passes. It is billable for payment year 2026.
Coder answer: D3A.098 is billable and maps to V28 HCC 22, Bladder, Colorectal, and Other Cancers. Open it in the Code Book for the tabular path, RAF, and MEAT checklist.

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 review for D3A.098
For D3A.098, 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
D3A.098 is the ICD-10-CM diagnosis code for benign carcinoid tumors of other sites. A benign hormone-producing tumor located in sites other than the common neuroendocrine tumor locations (such as the pancreas, ovary, or other organs). D3A.098 sits in the ICD-10-CM chapter for neoplasms (c00-d49), within the section covering benign neuroendocrine tumors (d3a).
Under the CMS-HCC V28 risk adjustment model, D3A.098 maps to Bladder, Colorectal, and Other Cancers (HCC 22) with a source-labeled community, non-dual, aged reference coefficient of 0.363. For CY2026 non-PACE Medicare Advantage, CMS uses 100% of the 2024 CMS-HCC model (V28). PACE uses a separate model blend. Source-labeled code-level coefficients are references, not member totals. Actual contribution depends on complete member context, hierarchy and cleanup rules, interactions, and model year. HCC Buddy's RAF Calculator supports CMS-HCC V28 PY2026 and shows no score unless every required source and calculation check passes.
Document the specific anatomical site clearly in the medical record for accurate coding assignment. For D3A.098, 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. 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, source-labeled coefficient references, and MEAT documentation criteria for D3A.098 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Document the specific anatomical site clearly in the medical record for accurate coding assignment
- •Review the pathology report to confirm benign behavior and neuroendocrine differentiation
Clinical Significance
This code captures benign carcinoid tumors arising at anatomical sites not covered by other specific D3A codes, such as the pancreas, ovary, testis, or other uncommon locations. These tumors are rare and may exhibit unique hormonal profiles depending on their site of origin, requiring specialized pathologic evaluation.
Documentation Requirements
- ✓Documentation must specify the anatomical site and confirm neuroendocrine differentiation with benign behavior on pathology.
- ✓Immunohistochemical staining results (chromogranin A, synaptophysin) should be documented.
- ✓Any functional hormone secretion should be noted along with relevant laboratory values.
Commonly Confused Codes
- •C7A.098 (malignant carcinoid of other sites) is the malignant counterpart.
- •Site-specific benign neoplasm codes (such as D13.6 for benign neoplasm of pancreas) may be appropriate if the tumor lacks neuroendocrine differentiation.
- •D3A.8 (other benign neuroendocrine tumors) is used for non-carcinoid neuroendocrine tumors.
