Is T14.91XA an HCC code?

Yes. T14.91XA (Suicide attempt, initial encounter) maps to HCC 155, Major Depression, Moderate or Severe, without Psychosis under the CMS-HCC V28 risk adjustment model, with a source-labeled community non-dual aged reference coefficient of 0.299. 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: T14.91XA is billable and maps to V28 HCC 155, Major Depression, Moderate or Severe, without Psychosis. 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 T14.91XA

For T14.91XA 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 T14.91XA during that encounter, not just copy-forwarded from a problem list.

What This Code Means

T14.91XA is the ICD-10-CM diagnosis code for suicide attempt, initial encounter. T14.91XA sits in the ICD-10-CM chapter for injury, poisoning and certain other consequences of external causes (s00-t88), within the section covering injury of unspecified body region (t14).

Under the CMS-HCC V28 risk adjustment model, T14.91XA maps to Major Depression, Moderate or Severe, without Psychosis (HCC 155) with a source-labeled community, non-dual, aged reference coefficient of 0.299. No V24 mapping is shown for T14.91XA; 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.

Coders should report T14.91XA only when the provider documentation supports the specific condition described, since more specific codes within the same hierarchy can capture additional clinical detail. Because T14.91XA 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 T14.91XA sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.

Source: official CMS ICD-10-CM order and addenda files, FY2016 through FY2027.

Because T14.91XA maps to an HCC category, the documentation must satisfy MEAT criteria (Monitor, Evaluate, Assess, or Treat) before the diagnosis is used for risk adjustment.

T14.91XA maps to CMS-HCC V28 category 155, Major Depression, Moderate or Severe, without Psychosis. See the ICD-10 to HCC mapping hub for how the V28 crosswalk works. The mapping identifies a payment HCC category for T14.91XA. 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.
