About T14.91XA
T14.91XA is the ICD-10-CM diagnosis code for suicide attempt, initial encounter. It belongs to category T14 (injury of unspecified body region), block T14 (injury of unspecified body region) and chapter 19 (injury, poisoning and certain other consequences of external causes). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.
The 7th character "A" means initial encounter: use it while the patient is receiving active treatment for the condition.
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
In MS-DRG v44.0, it is part of the grouping logic for DRG 913 (Traumatic Injury with MCC, relative weight 1.5455), DRG 914 (Traumatic Injury without MCC, relative weight 0.9285), DRG 963 (Other Multiple Significant Trauma with MCC, relative weight 2.6363), DRG 964 (Other Multiple Significant Trauma with CC, relative weight 1.4972) and DRG 965 (Other Multiple Significant Trauma without CC/MCC, relative weight 1.0059), in MDC 21 (Injuries, Poisonings and Toxic Effects of Drugs) and MDC 24 (Multiple Significant Trauma), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
It was added in FY2018, effective October 1, 2017.
Before ICD-10, this condition was coded in ICD-9-CM as 959.9 (unspecified site injury) and E958.9 (suicide and self-inflicted injury by unspecified means).
