Polio and Post-Polio Syndrome
Also called: Infantile paralysis, PPS, Poliomyelitis
Polio is an infectious disease caused by a virus. The virus lives in an infected person's throat and intestines. It is most often spread by contact with the stool of an infected person. You can also get it from droplets if an infected person sneezes or coughs. It can contaminate food and water if people do not wash their hands.
Most people have no symptoms. If you have symptoms, they may include fever, fatigue, nausea, headache, flu-like symptoms, stiff neck and back, and pain in the limbs. A few people will become paralyzed. There is no treatment to reverse the paralysis of polio.
Some people who've had polio develop post-polio syndrome (PPS) years later. Symptoms include tiredness, new muscle weakness, and muscle and joint pain. There is no way to prevent or cure PPS.
The polio vaccine has wiped out polio in the United States and most other countries.

General Equivalence Map Definitions
The ICD-9 and ICD-10 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.
