Information for Patients


Diphtheria

Diphtheria is a serious bacterial infection. You can catch it from a person who has the infection and coughs or sneezes. You can also get infected by coming in contact with an object, such as a toy, that has bacteria on it.

Diphtheria usually affects the nose and throat. Symptoms include

  • Sore throat
  • Swollen glands in the neck
  • Fever
  • Weakness

Your doctor will diagnose it based on your signs and symptoms and a lab test. Getting treatment for diphtheria quickly is important. If your doctor suspects that you have it, you'll start treatment before the lab tests come back. Treatment is with antibiotics.

The diphtheria, pertussis, and tetanus vaccine can prevent diphtheria, but its protection does not last forever. Children need another dose, or booster, at about age 12. Then, as adults, they should get a booster every 10 years. Diphtheria is very rare in the United States because of the vaccine.

ICD-10 Footnotes

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.
