Defense Health Agency

"On October 1, 2013, the Department of Defense established the Defense Health Agency (DHA) to manage the activities of the Military Health System. These activities include those previously managed by TRICARE Management Activity (TMA), which was disestablished on the same date. During the next several months, all TMA websites will change to reflect the new DHA. We appreciate your patience during this transition."

Unified Biostatistical Utility (UBU)


The Unified Biostatistical Utility (UBU) group is responsible for the detailed work of the analysis required to standardize biostatistical data elements, definitions, data collection processes, procedure codes, diagnoses and algorithms across the Military Health System.

The UBU consists of multi-disciplinary functional experts from the Army, Navy and Air Force covering a broad range of business functions with an emphasis in biostatistical, clinical, financial or managed care areas.

Coding Guidelines

The UBU consists of a subgroup of service coders who work together to develop and publish the Department of Defense (DoD) coding guidelines. The following guidelines are available as reference/guidance for MHS personnel when coding patient care in our MHS information systems.

The following files include guidelines for coding professional and specialty services, as well as inpatient institutional services:

ICD 10 Activities

International Classification of Diseases, 10th RevisionThe Military Health System (MHS) will transition on 1 Oct 2013 to using the ICD-10-CM for healthcare encounter diagnoses, conditions, factors and causes of injury. For discharges on the same date, it will transition to using ICD-10-Procedure Coding System (PCS) for inpatient institutional procedure data collection. To this end, the MHS is taking many actions. These include but are not limited to:

Awareness training in the application of ICD-10-CM and ICD-10-PCS codes. This primarily is occurring at the MHS Revenue Cycle (formerly UBU/UBO) Conference. As the transition date becomes closer, just-in-time/specialty specific training will be available in various educational applications.

Modification of data collection systems to accomodate the longer codes.

Review of forms, manuals, directives and other documents for ICD-9-CM codes. Updating to include ICD-9-CM, ICD-10-CM and ICD-10-PCS as applicable.
