Object Description
One record per ICD-10-CM diagnosis code, including "non-leaf" codes representing categories of finer-grained codes; includes diagnosis classification information from WHO and AHRQ.
The sources for this object are CMS ICD-10-CM codes, AHRQ Clinical Classifications Software (CCS) for ICD-10-CM, WHO ICD-10-CM Diagnosis Classifications, and the Ursa Standard Value Sets for helping with the categories.

- WHO ICD-10 Chapter Description -- The World Health Organization (WHO) Chapter is the highest level of the ICD-10 classification hierarchy, organizing the full code set into 22 broad categories largely based on body system (e.g., "Diseases of the circulatory system," "Diseases of the respiratory system"), though several chapters cut across body systems to group codes by etiology or context — such as infectious diseases, neoplasms, external causes of morbidity, and pregnancy/childbirth. Chapters are typically designated by Roman numerals (I–XXII) and serve as the primary lens for high-level disease burden reporting, population health trending, and cost stratification.
- WHO ICD-10 Block Description -- The World Health Organization (WHO) ICD-10 "Block" is the intermediate grouping level that subdivides each chapter into roughly 260–290 contiguous code ranges (e.g., I60–I69 for cerebrovascular diseases within the circulatory chapter), providing clinically meaningful subcategories that share common pathology, anatomy, or mechanism. Blocks are especially useful in analytics when chapter-level analysis is too coarse but individual diagnosis codes are too granular — for example, comparing utilization across types of heart disease or distinguishing falls from motor vehicle injuries within the external causes chapter.
- Is Ursa Hospital Admission Condition-Treatment Type Tier 1 Behavioral Health -- Indicates an admission met the criteria for a Behavioral Health admission, a category of the Ursa Hospital Admission Condition-Treatment Type Tier 1 classification system. Behavioral Health admissions relate to behavioral health conditions and related treatments. (See also [URSA-CORE] Ursa Hospital Admission Condition-Treatment Type)
- Is Ursa Hospital Admission Condition-Treatment Type Tier 1 Maternity -- Indicates an admission met the criteria for a Maternity admission, a category of the Ursa Hospital Admission Condition-Treatment Type Tier 1 classification system. Maternity admissions relate to pregnancy and childbirth. (See also [URSA-CORE] Ursa Hospital Admission Condition-Treatment Type)
