Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

7th Character Note
Certain ICD-10-CM categories have applicable 7th characters. The applicable 7th character is required for all codes within the category, or as the notes in the Tabular List instruct. The 7th character must always be the 7th character in the data field. If a code that requires a 7th character is not 6 characters, a placeholder X must be used to fill in the empty characters.

About the X73 Code Range
The ICD-10 code X73 series classifies instances of intentional self-harm caused by the discharge of rifles, shotguns, and other larger firearms. These codes specify the type of firearm used, such as shotgun (X73.0), hunting rifle (X73.1), machine gun (X73.2), or other larger firearms (X73.8), including unspecified types (X73.9).
This group of codes is used to document cases where an individual deliberately harms themselves using a large firearm. Each code includes further subdivisions to indicate the timing and treatment status, including initial encounters (e.g., X73.0XXA for initial self-harm by shotgun discharge), subsequent encounters (X73.0XXD), and sequela (X73.0XXS) for complications or conditions resulting from earlier injuries. These distinctions help healthcare providers and medical coders accurately identify the specific firearm involved and the stage of care, which is crucial for clinical management and reporting. Using the correct ICD-10 code for intentional self-harm by rifle or shotgun improves clarity in medical records and supports appropriate mental health and trauma interventions.
