Diagnosis Code Z44.21
Information for Medical Professionals
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) 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.
The code Z44.21 is exempt from POA reporting.
Information for Patients
Some eye problems are minor and don't last long. But some can lead to a permanent loss of vision.
Common eye problems include
- Refractive errors
- Cataracts - clouded lenses
- Glaucoma - a disorder caused by damage to the optic nerve
- Retinal disorders - problems with the nerve layer at the back of the eye
- Macular degeneration - a disease that destroys sharp, central vision
- Diabetic eye problems
- Conjunctivitis - an infection also known as pinkeye
Your best defense is to have regular checkups, because eye diseases do not always have symptoms. Early detection and treatment could prevent vision loss. See an eye care professional right away if you have a sudden change in vision, if everything looks dim, or if you see flashes of light. Other symptoms that need quick attention are pain, double vision, fluid coming from the eye, and inflammation.
