If FEMALE is inconsistent with diagnoses (EDX03), procedures (EPR03), ICD-9-CM or ICD-10-CM/PCS procedures (EPR03), or HCPCS procedures (ECPT02), FEMALE is set to inconsistent (.C).

In HCUP databases before 1998, this data element is called SEX.

State Specific Notes

California

Central Distributor only - because of confidentiality restrictions, gender (FEMALE) is suppressed on some records.



Colorado

According to the documentation available from the source, "Other/Unknown" includes patients undergoing sex changes, undetermined sex, live births with congenital abnormalities, and patients whose sex was unavailable from any source document. The source value for "Other/Unknown" was recoded to missing (.), during HCUP processing of 1988-1992 discharges.

From 1993 - 2002, "Other/Unknown" was recoded to invalid (.A) during HCUP processing. From 2003 - 2007 "Other/Unknown" was recoded to missing (.). Beginning in 2008, "Other/Unknown" was once again recoded to invalid (.A)



Utah

Through the 2002 data year, the source value "E" for "Encrypted patient gender (confidential data)" is recoded to missing (FEMALE = .).

Utah encrypts the patient gender for the following two conditions:

  1. Patients with the Major Diagnosis Code of "Human Immunodeficiency Virus Infection" (value 25) and
  2. Diagnosis Related Groups "Alcohol/Drug Abuse or Dependence" (values 433-437).

Beginning with the 2003 data, Utah supplies an unmasked file.

Beginning with the 2015 data, the HCUP data element FEMALE is set to missing (.) in the Central Distributor SID for records involving substance abuse or HIV infection. This was done at the request of the Utah Partner organization.
