Convert to ICD-9 Additional informationCallout TooltipGeneral Equivalence Map
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.

Present on Admission (POA) Additional informationCallout TooltipPresent 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.

The code Q31.8 is exempt from POA reporting.

Birth Defects

A birth defect is a problem that happens while a baby is developing in the mother's body. Most birth defects happen during the first 3 months of pregnancy. One out of every 33 babies in the United States is born with a birth defect.

A birth defect may affect how the body looks, works or both. Some birth defects like cleft lip or neural tube defects are structural problems that can be easy to see. To find others, like heart defects, doctors use special tests. Birth defects can vary from mild to severe. Some result from exposures to medicines or chemicals. For example, alcohol abuse can cause fetal alcohol syndrome. Infections during pregnancy can also result in birth defects. For most birth defects, the cause is unknown.

Some birth defects can be prevented. Taking folic acid can help prevent some birth defects. Talk to your doctor about any medicines you take. Some medicines can cause serious birth defects.

Babies with birth defects may need surgery or other medical treatments. Today, doctors can diagnose many birth defects in the womb. This enables them to treat or even correct some problems before the baby is born.

Throat Disorders

Also called: Pharyngeal disorders

Your throat is a tube that carries food to your esophagus and air to your windpipe and larynx. The technical name for your throat is the pharynx.

Throat problems are common. You've probably had a sore throat. The cause is usually a viral infection, but other causes include allergies, infection with strep bacteria or the leaking of stomach acids back up into the esophagus, called GERD.

Other problems that affect the throat include

  • Tonsillitis - an infection in the tonsils
  • Cancer
  • Croup - inflammation, usually in small children, which causes a barking cough
  • Laryngitis - swelling of the voice box, which can cause a hoarse voice or loss of voice

Most throat problems are minor and go away on their own. Treatments, when needed, depend on the problem.

  • Blockage of upper airway
  • Epiglottitis
  • Glossopharyngeal neuralgia
  • Herpangina
  • Laryngitis
  • Laryngoscopy
  • Retropharyngeal abscess
  • Strep throat
  • Throat swab culture
