Inpatient Use

The Texas Health Care Information Collection program (THCIC) collects discharge data from state licensed hospitals except those statutorily exempt from the reporting requirement. This dashboard displays data from patients who received inpatient care without being seen in a hospital emergency department. Data are summarized by 1) Primary Diagnosis Groups, which includes the Major Diagnostic Categories (MDC) or All-Patient Refined-Diagnosis Related Groups (APR-DRG) classification systems or by 2) Procedure Groups, a classification system for categorizing types of outpatient procedures.

Data Source

Texas Health Care Information Collection (THCIC)

Data Source and Description

The Texas Health Care Information Collection (THCIC) was created by Chapter 108 of the Texas Health and Safety Code (THSC) and is responsible, under Sections 108.011 through 108.0135, for collecting hospital discharge data from all state licensed hospitals except those that are statutorily exempt from the reporting requirement. The Inpatient Utilization dashboard uses the Texas hospital inpatient discharge Public Use Data Files (PUDF). For more details on the data source, data collection and data dictionary, see the Texas Outpatient Public Use Data File.

Measure Information

Inpatient hospitalization

Hospitalizations for patients who were admitted into the hospital for care. The inpatient hospital stay may last several hours to days, weeks or years, depending upon the condition or status of the patient before being discharged.


County of patients who live in Texas (county of residence). “Missing” reflects statewide visits where the county was not recorded, unknown or suppressed. Thus, in some years, the statewide total will be greater than the sum of the county totals.

First Payor Source

The expected payer for the outpatient ED visit. The first-listed payer is used to categorize into general groups.


The patient’s race and ethnicity are combined. Hispanic race/ethnicity includes patients who identify themselves as Hispanic ethnicity regardless of race. The rest are grouped into their specific non-Hispanic race including White, Black, and Other.

Patient status

Patient status as of the ending date of service for the period of care reported.

Source of Admission

Indicates source of the admission such as a different hospital or healthcare facility, non-healthcare facilities, or law enforcement/judicial court ordered.


Data are by patient county and address. Null values indicate either out-of-state or incomplete addresses.

Public Health Regions

Eight regions as categorized and defined by Texas DSHS

Metropolitan Status

Metropolitan Statistical Area as defined by the Office of Management and Budget

Major Diagnostic Categories (MDC)

The Major Diagnostic Categories (MDC) are 25 mutually exclusive diagnosis areas that are formed from all possible principal diagnoses (primary ICD-10-CM diagnosis codes). The diagnoses in each MDC correspond to a single organ system or etiology and in general are associated with a particular medical specialty.

All Patient Refined-Diagnosis Related Group (APR-DRG)

The 3M� APR-DRGs are a patient classification scheme which provides a means of relating the type of patients a hospital treats (i.e., its case mix) to the costs incurred by the hospital. The APR-DRGs consist of classes of patients that are similar clinically and in terms of their consumption of hospital resources.

Principal Procedure Group

The Principal Procedure Group utilizes the Clinical Classifications Software (CCS). It is a procedure categorization scheme based on the International Classification of Diseases, 10th Revision, Procedure Coding System (ICD-10-PCS). It collapses ICD-10-PCS’s multitude of procedure codes into a manageable number of clinically meaningful categories that are sometimes more useful for presenting descriptive statistics than are individual ICD-10-PCS codes. It was developed by the Healthcare Cost and Utilization Project (HCUP), a Federal-State-Industry partnership sponsored by the Agency for Healthcare Research and Quality (AHRQ).

Risk of Mortality

Assignment of a risk of mortality score from the All Patient Refined Diagnosis Related Group (APR-DRG) from the 3M™ APR-DRG Grouper. Indicates the likelihood of dying.

Severity of Illness

Assignment of a severity of illness score from the All Patient Refined Diagnosis Related Group (APR-DRG) from the 3M™ APR-DRG Grouper. Indicates the extent of physiologic decompensation.

Length of Stay

Number of days from admission/start of care to the ending date of service/care.

Total (Hospital) Charges

Sum of accommodation charges, non-covered accommodation charges, ancillary charges, and non-covered ancillary charges.
