Post-Traumatic Stress Disorder
Also called: PTSD
Post-traumatic stress disorder (PTSD) is a real illness. You can get PTSD after living through or seeing a traumatic event, such as war, a hurricane, sexual assault, physical abuse, or a bad accident. PTSD makes you feel stressed and afraid after the danger is over. It affects your life and the people around you.
PTSD can cause problems like
- Flashbacks, or feeling like the event is happening again
- Trouble sleeping or nightmares
- Feeling alone
- Angry outbursts
- Feeling worried, guilty, or sad
PTSD starts at different times for different people. Signs of PTSD may start soon after a frightening event and then continue. Other people develop new or more severe signs months or even years later. PTSD can happen to anyone, even children.
Treatment may include talk therapy, medicines, or both. Treatment might take 6 to 12 weeks. For some people, it takes longer.

General Equivalence Map Definitions
The ICD-10 and ICD-9 GEMs are used to facilitate linking between the diagnosis codes in ICD-9-CM and the new ICD-10-CM code set. The GEMs are the raw material from which providers, health information vendors and payers can derive specific applied mappings to meet their needs.
- Approximate Flag - The approximate flag is on, indicating that the relationship between the code in the source system and the code in the target system is an approximate equivalent.
- No Map Flag - The no map flag indicates that a code in the source system is not linked to any code in the target system.
- Combination Flag - The combination flag indicates that more than one code in the target system is required to satisfy the full equivalent meaning of a code in the source system.
Present on Admission
The Present on Admission (POA) indicator is used for diagnosis codes included in claims involving inpatient admissions to general acute care hospitals. POA indicators must be reported to CMS on each claim to facilitate the grouping of diagnoses codes into the proper Diagnostic Related Groups (DRG). CMS publishes a listing of specific diagnosis codes that are exempt from the POA reporting requirement.
