Benign neoplasm of cerebral meninges

A benign (non-cancerous) tumor that grows in the protective membrane surrounding the brain. These tumors are typically slow-growing and may not cause symptoms unless they become large enough to press on brain tissue.

Benign neoplasm of the cerebral meninges most commonly represents a meningioma, which is the most frequent primary intracranial tumor, accounting for approximately 30% of all brain tumors.

Buddy Documentation Tip

HCC Buddy guidance
MRI or CT imaging documenting the meningeal-based mass with characteristic features of meningioma.
Document tumor size, location, mass effect, and whether the patient is symptomatic.
If surgically resected, pathology must confirm WHO Grade I benign status.
Include the treatment approach (observation, surgery, radiation) and surveillance interval.

Audit Caution

HCC Buddy guidance
The WHO grade is critical: Grade I is benign (D32.0), Grade II is uncertain behavior (D42.0), and Grade III is malignant (C70.0).
Do not assign D32.0 for an atypical or anaplastic meningioma.
Incidental meningiomas found on imaging still warrant coding if documented.
Multiple meningiomas should each be coded if separately documented.

Common Mistakes

HCC Buddy guidance
D32.1 (benign neoplasm of spinal meninges) is for spinal meningiomas
D42.0 (neoplasm of uncertain behavior of cerebral meninges) is for WHO Grade II atypical meningiomas
C70.0 (malignant neoplasm of cerebral meninges) is for WHO Grade III anaplastic meningiomas
D33.0/D33.1 (benign brain neoplasm) is for intra-axial tumors, not meningeal.

Is D32.0 an HCC code?

Yes. D32.0 (Benign neoplasm of cerebral meninges) maps to HCC 23, Prostate, Breast, and Other Cancers and Tumors under the CMS-HCC V28 risk adjustment model, with a source-labeled community non-dual aged reference coefficient of 0.186. 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: D32.0 is billable and maps to V28 HCC 23, Prostate, Breast, and Other Cancers and Tumors. Open it in the Code Book for the tabular path, RAF, and MEAT checklist.

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 D32.0

For D32.0 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 D32.0 during that encounter, not just copy-forwarded from a problem list.

What This Code Means

D32.0 is the ICD-10-CM diagnosis code for benign neoplasm of cerebral meninges. A benign (non-cancerous) tumor that grows in the protective membrane surrounding the brain. These tumors are typically slow-growing and may not cause symptoms unless they become large enough to press on brain tissue. D32.0 sits in the ICD-10-CM chapter for neoplasms (c00-d49), within the section covering benign neoplasms, except benign neuroendocrine tumors (d10-d36).

Under the CMS-HCC V28 risk adjustment model, D32.0 maps to Prostate, Breast, and Other Cancers and Tumors (HCC 23) with a source-labeled community, non-dual, aged reference coefficient of 0.186. No V24 mapping is shown for D32.0; use the applicable model and payment year when reviewing the V28 mapping. 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. 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.

Verify the location is specifically the cerebral meninges (brain covering) rather than spinal meninges, which would use a different code. Because D32.0 maps to an HCC category, the provider's documentation must satisfy MEAT criteria (Monitor, Evaluate, Assess, or Treat) before the diagnosis is used for risk adjustment. 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 D32.0 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.

Coding Tips

  • •Verify the location is specifically the cerebral meninges (brain covering) rather than spinal meninges, which would use a different code
  • •Confirm the neoplasm is benign; if malignant or of uncertain behavior, use the appropriate C-code or D37-D48 range instead

Clinical Significance

Benign neoplasm of the cerebral meninges most commonly represents a meningioma, which is the most frequent primary intracranial tumor, accounting for approximately 30% of all brain tumors. Most meningiomas are slow-growing WHO Grade I tumors that may remain asymptomatic for years, discovered incidentally on imaging. However, they can cause significant neurological symptoms when they compress adjacent brain structures.

Documentation Requirements

  • ✓MRI or CT imaging documenting the meningeal-based mass with characteristic features of meningioma.
  • ✓Document tumor size, location, mass effect, and whether the patient is symptomatic.
  • ✓If surgically resected, pathology must confirm WHO Grade I benign status.
  • ✓Include the treatment approach (observation, surgery, radiation) and surveillance interval.

Commonly Confused Codes

  • •D32.1 (benign neoplasm of spinal meninges) is for spinal meningiomas
  • •D42.0 (neoplasm of uncertain behavior of cerebral meninges) is for WHO Grade II atypical meningiomas
  • •C70.0 (malignant neoplasm of cerebral meninges) is for WHO Grade III anaplastic meningiomas
  • •D33.0/D33.1 (benign brain neoplasm) is for intra-axial tumors, not meningeal.

Because D32.0 maps to an HCC category, the documentation must satisfy MEAT criteria (Monitor, Evaluate, Assess, or Treat) before the diagnosis is used for risk adjustment.

D32.0 maps to CMS-HCC V28 category 23, Prostate, Breast, and Other Cancers and Tumors. See the ICD-10 to HCC mapping hub for how the V28 crosswalk works. The mapping identifies a payment HCC category for D32.0. Review its source-labeled HCC coefficient above, check the RAF Calculator with complete member context for CMS-HCC V28 PY2026, and confirm the documentation the chart needs before the code is submitted. HCC Buddy shows no RAF score unless every required source and calculation check passes.
