T14.91XA is a billable ICD-10-CM diagnosis code for suicide attempt, initial encounter. The 7th character A marks it as an initial encounter code, used while the patient is receiving active treatment. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 913 through 914, 963 through 965. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under External cause codes: intent of injury, self-harm; External cause codes: unspecified mechanism; and Other unspecified injury.

For Medicare Advantage risk adjustment, T14.91XA maps to CMS-HCC Category 155 (Major Depression, Moderate or Severe, without Psychosis) under the V28 model, adding a risk factor of about 0.299 for a community, non-dual, aged beneficiary in payment year 2027.

Questions About T14.91XAOverview

What is the ICD-10 code for suicide attempt, initial encounter?

The ICD-10-CM code for suicide attempt, initial encounter is T14.91XA (sometimes written as T1491XA). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

Is T14.91XA (Suicide attempt) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report suicide attempt, initial encounter on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What does the 7th character A in T14.91XA mean?

The final character A marks the initial encounter: use it while the patient is receiving active treatment for suicide attempt, such as an emergency visit or first evaluation.

What MS-DRG does T14.91XA group to?

When suicide attempt, initial encounter is the principal diagnosis on an inpatient stay, it groups to MS-DRG 964, 965, 914, 913, 963, with relative weights from 0.9281 to 2.6361 depending on complications. Higher weights mean higher Medicare reimbursement.

Can T14.91XA be reported with T07?

Not as a rule. The Excludes1 note at T14, which applies to T14.91XA, lists "multiple unspecified injuries (T07)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).

What HCC is T14.91XA?

T14.91XA (suicide attempt, initial encounter) maps to CMS-HCC Category 155 (Major Depression, Moderate or Severe, without Psychosis), commonly written as HCC 155, in the CMS-HCC V28 model used for Medicare Advantage risk adjustment in payment year 2027. It mapped to HCC 59 under the retired V24 model. It also maps in the PACE (CMS-HCC V22), ESRD (V21), and ESRD (V24) models. In the Part D prescription drug model it maps to RxHCC 132.

Does T14.91XA risk-adjust for Medicare Advantage payment?

Yes. When documented and reported on a Medicare Advantage encounter, T14.91XA adds a risk adjustment factor of about 0.299 to the beneficiary's RAF score for a community, non-dual, aged enrollee (published V28 weights range from 0.108 to 0.316 depending on the payment segment). A more severe related category (HCC 151, HCC 152, HCC 153, and HCC 154) supersedes it when both are reported. See the full factor table on the HCC 155 category page.
