Convert to ICD-9 General 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.
- V56.31 - Hemodialysis testing (approximate) 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.
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 Z49.31 is exempt from POA reporting.

Information for Patients
Also called: Renal dialysis
When your kidneys are healthy, they clean your blood. They also make hormones that keep your bones strong and your blood healthy. When your kidneys fail, you need treatment to replace the work your kidneys used to do. Unless you have a kidney transplant, you will need a treatment called dialysis.
There are two main types of dialysis. Both types filter your blood to rid your body of harmful wastes, extra salt, and water.
- Hemodialysis uses a machine. It is sometimes called an artificial kidney. You usually go to a special clinic for treatments several times a week.
- Peritoneal dialysis uses the lining of your abdomen, called the peritoneal membrane, to filter your blood.
