Suicidal Ideation ICD 10 CM Code R45.851
Suicidal ideation, also known as suicidal thoughts, concerns thoughts about or an unusual preoccupation with suicide. The range of suicidal ideation varies greatly from fleeting thoughts to extensive thoughts to detailed planning, role-playing (e.g., standing on a chair with a noose), and incomplete attempts, which may be deliberately constructed to not complete or to be discovered, or maybe fully intended to result in death. Still, the individual survives (e.g., in the case of a hanging in which the cord breaks). According to Suicidal Ideation ICD-10-CM Code R45.851 guidelines, this code should not be used as a principal diagnosis code when a related definitive diagnosis has been established.

Suicide is the 10th leading cause of death in the United States and the 2nd leading cause of death in people between 10 and 34. The gravity of the situation can be seen in the fact that every 11 minutes, one person loses their life to suicide. If you are considering suicide or know of someone that feels suicidal, reach out for help and suicidal ideation treatment because you might save a lifeāyour own or someone elseās.

- Males have a suicide rateĀ 3.7 times higherĀ compared with females.
- American Indian/Alaska Native individuals have theĀ highest suicide ratesĀ in the nation, followed by non-Hispanic white individuals. Suicide rates among Hispanic, Black, and Asian/Pacific Islander individuals are significantly lower than rates among American Indian/Alaska Native and white individuals.
- Older adultsĀ have a higher suicide rate when compared with younger adults and adolescents. By age and gender, the highest suicide rate is among males ages 65 and older, followed by males ages 45 to 54. Among females, those ages 45-54 have the highest rate, followed by those ages 55-64.
- Suicide rates amongĀ veteransĀ were 1.5 times greater than non-veterans, after adjusting for age and gender in 2016.
- There is a difference between those residing in rural and urban areas.
- LGBTQ adults and youth are compared with heterosexual adults and youth.
