Buddy Documentation Tip
Current with CMS: FY2026 ICD-10-CM Apr 1 update (effective Apr 1 – Sep 30, 2026) · CMS-HCC V28, 100% phased in for payment year 2026. FY2027 code set already staged for October 1, 2026. How HCC Buddy stays current →
Is G31.87 an HCC code?
G31.87 has no mapping under the current CMS-HCC V28 community payment model. G31.87 has a separate mapping under the CMS-HCC ESRD model (HCC 52 (Dementia Without Complication)) and the Part D RxHCC model (HCC 112 (Dementia, Except Alzheimer's Disease)); 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 review for G31.87
For G31.87, 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
G31.87 is the ICD-10-CM diagnosis code for primary progressive apraxia of speech. Primary progressive apraxia of speech is a neurodegenerative condition where a person gradually loses the ability to plan and execute the movements needed for speech, despite understanding language. G31.87 sits in the ICD-10-CM chapter for diseases of the nervous system (g00-g99), within the section covering other degenerative diseases of the nervous system (g30-g32).
G31.87 has no mapping under the current CMS-HCC V28 community payment model. G31.87 has a separate mapping under the CMS-HCC ESRD model (HCC 52 (Dementia Without Complication)) and the Part D RxHCC model (HCC 112 (Dementia, Except Alzheimer's Disease)); 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.
Distinguish from other speech disorders; this is specifically a motor planning disorder that worsens over time.
HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for G31.87 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Distinguish from other speech disorders; this is specifically a motor planning disorder that worsens over time
- •Document the progressive nature and any associated cognitive or language changes for complete clinical picture
