Information for Patients


Facial Injuries and Disorders

Face injuries and disorders can cause pain and affect how you look. In severe cases, they can affect sight, speech, breathing and your ability to swallow. Broken bones, especially the bones of your nose, cheekbone and jaw, are common facial injuries.

Certain diseases also lead to facial disorders. For example, nerve diseases like trigeminal neuralgia or Bell's palsy sometimes cause facial pain, spasms and trouble with eye or facial movement. Birth defects can also affect the face. They can cause underdeveloped or unusually prominent facial features or a lack of facial expression. Cleft lip and palate are a common facial birth defect.

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.
