Drown after fall into bathtub, undetermined intent, subs

This code signifies a patient presenting for follow-up care or management of complications stemming from a drowning or near-drowning incident that occurred after an unintentional fall into a bathtub. The intent of the fall and subsequent submersion cannot be definitively determined from the available documentation.

Use this code for subsequent encounters when a patient is being treated for sequelae such as aspiration pneumonia, hypoxic brain injury, or other long-term effects following a bathtub submersion where the intent (accidental, self-harm, assault) remains unclear. This applies to visits after the initial acute care for the event.

• Ensure documentation clearly states "undetermined intent" for the fall and submersion.
• This code is for subsequent encounters; use the 'A' or 'D' seventh character for initial or subsequent care, respectively.
• Always code any associated injuries or conditions resulting from the drowning event.
