Highlights

medicalcoder 0.8.0 adds support for the AHRQ Elixhauser Comorbidity Software Refined v2026, improves performance for tibble and data.table inputs, and corrects several comorbidity mappings.

New features

  • Added elixhauser_ahrq2026 support to comorbidities() (#32).
  • Added optimized dplyr-based data manipulation for tibble inputs.
  • Added mdcr_unique() to improve tibble and data.table performance (#31).

Corrections

  • Corrected AHRQ ICD-10 conditional and multiple-comorbidity mappings for fiscal years 2023–2026.
  • Improved the Quan 2005 Elixhauser mappings:
    • Removed F42.2 from depression.
    • Added G36.x and ICD-9-CM 333.4 to neurological disorders.
  • Added the historically assignable ICD-9-PCS code 37.5 to the relevant PCCC code sets (#38).
  • Fixed summaries for zero-row inputs and consistently return NA instead of NaN for zero counts (#26, #27).
  • Added validation for input data structures (#41).
  • Added validation for empty regular-expression patterns in lookup_icd_codes() (#42).

Other changes

  • Expanded the internal ICD-9 database to distinguish CDC and CMS sources.
  • Improved cumulative comorbidity flagging performance.
  • Clarified present-on-admission behavior with cumulative flagging (#28).
  • Improved documentation, including guidance for users transitioning from the pccc package.
