Tables

Tables in the METL database.

📄️icd_procedure_hierarchy_title_lookup

Stores the titles used to describe each of the hierarchy levels, which vary depending on the section code (hierarchy level 1). For example in 'Medical and Surgical procedures' the letters of the procedure describe the 'section', 'body system', 'operation', etc. but for 'Physical Rehabilitation and Diagnostic Audiology', the letters of the procedure describe the 'section', 'section qualifier', 'type', etc. This table makes it possible to correctly build a ICD-procedure drill-down UI.

📄️transparency_provider_set

Which provider sets a provider reference belongs to. A set is one distinct combination of references that rates apply to, so a rate names its combination with a provider_set_id instead of carrying a row per provider. The memberships are an array per reference because a row each costs over thirty times as much, nearly all of it per row overhead and index entries for a four byte value. A set is not a payer concept such as a network or a tier, a single reference belongs to thousands of them.
