About W67.XXXA
W67.XXXA is the ICD-10-CM diagnosis code for accidental drowning and submersion while in swimming-pool, initial encounter. It belongs to category W67 (accidental drowning and submersion while in swimming-pool), block W65-W74 (accidental non-transport drowning and submersion) and chapter 20 (external causes of morbidity). 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.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
Before ICD-10, this condition was coded in ICD-9-CM as E910.8 (other accidental drowning or submersion).
