2027 ICD-10-CM Diagnosis Code W73Other specified cause of accidental non-transport drowning and submersion
W73 is a non-billable ICD-10-CM category code for other specified cause of accidental non-transport drowning and submersion, so it cannot be submitted on claims. Use a more specific code from this category instead, such as W73.XXXA, W73.XXXD, and W73.XXXS.

Instructional NotesGuidance
Instructions from the official ICD-10-CM Tabular List that apply to W73: its own notes plus those printed at block W65-W74 and Chapter 20. A note printed at a category, block or chapter applies to every code under it.
Applicable To
Conditions this code is used for: synonyms of the title or, for "other specified" codes, the conditions assigned to it. The list is not exhaustive.
- Accidental drowning and submersion while in quenching tank
- Accidental drowning and submersion while in reservoir
Excludes1
Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.
Excludes2
Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.
Notes
General instructions on how these codes are used.
- This chapter permits the classification of environmental events and circumstances as the cause of injury, and other adverse effects. Where a code from this section is applicable, it is intended that it shall be used secondary to a code from another chapter of the Classification indicating the nature of the condition. Most often, the condition will be classifiable to Chapter 19, Injury, poisoning and certain other consequences of external causes (S00-T88). Other conditions that may be stated to be due to external causes are classified in Chapters I to XVIII. For these conditions, codes from Chapter 20 should be used to provide additional information as to the cause of the condition.
7th Character
Every code in the category takes a 7th character from the listed values, with the placeholder X filling any empty positions before it.
- The appropriate 7th character is to be added to code W73
- Ainitial encounter
- Dsubsequent encounter
- Ssequela

Patient EducationClinical
Drowning
People drown when they get too much water in their lungs. You can drown in as little as an inch or two of water. Babies can drown in a sink or bathtub. Preschoolers are most likely to drown in a swimming pool. People who have seizure disorders are also at risk in the water. Drowning can happen quickly and silently.

Code HistoryHistory
Questions About W73Overview
Is W73 a billable code?
No. This is a category header that groups the codes for other specified cause of accidental non-transport drowning and submersion, and headers cannot be submitted on claims. Claims for other specified cause of accidental non-transport drowning and submersion need a more specific code from this category, such as W73.XXXA, W73.XXXD, and W73.XXXS.
Can W73 be reported with W16.311?
Not as a rule. The Excludes1 note on W73 lists "accidental drowning and submersion due to fall into other water (W16.311, W16.321, W16.331)". 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).
