medicalcoder vs portfoliobacktest: at a glance
What is medicalcoder?
A comorbidity-coding package relicenses to BSD and grows past the American coding systems
medicalcoder maps ICD diagnosis codes to comorbidity conditions using the Charlson, Elixhauser, AHRQ and PCCC method families. Three releases since June 2026 moved it from a US-centric tool to one carrying Australian and Swedish modifications, added four new Charlson variants, and introduced a choice between precomputed code-condition links and regex mapping applied directly to input codes. The license moved from GPL-2 to BSD 3-Clause along the way.
What is portfoliobacktest?
Four dormant years end with a test fix, not a feature
portfolioBacktest runs portfolio strategies across multiple datasets and resampled windows, producing performance tables, leaderboards and charts. After a run of substantive releases through 2021 and early 2022 it went quiet for four years. The May 2026 release does one thing: fix unit tests against a breaking change in PerformanceAnalytics::Return.portfolio(), which now returns results for the full input series rather than only from the first weight date.

A comorbidity-coding package relicenses to BSD and grows past the American coding systems
◆ Current state
medicalcoder maps ICD diagnosis codes to comorbidity conditions using the Charlson, Elixhauser, AHRQ and PCCC method families. Three releases since June 2026 moved it from a US-centric tool to one carrying Australian and Swedish modifications, added four new Charlson variants, and introduced a choice between precomputed code-condition links and regex mapping applied directly to input codes. The license moved from GPL-2 to BSD 3-Clause along the way.
◆ Where it's heading
Two things are happening at once. The coding surface is broadening — ICD-10-AM, ICD-10-SE, Swedish register-based and MIMIC-IV-consistent Charlson methods — which points at users outside the US claims-data world. Separately, the package is hardening: validation on encounter ordering, deterministic result ordering, NA rather than NaN for zero counts, and corrected AHRQ and Quan mappings for fiscal years 2023 to 2026. The mapping argument is the first real fork in how the computation runs rather than what it covers.
◆ Prediction
Regex mapping is currently unavailable for charlson_beyrer2021 and the release notes flag it as a gap, so closing that is the most clearly signposted next step.

◆ Current state
portfolioBacktest runs portfolio strategies across multiple datasets and resampled windows, producing performance tables, leaderboards and charts.

The May 2026 release does one thing: fix unit tests against a breaking change in PerformanceAnalytics::Return.portfolio(), which now returns results for the full input series rather than only from the first weight date.
◆ Where it's heading
The development work is behind it. The 2019 to 2022 releases built the substance — parallel execution, resampling that works beyond stock data and beyond daily bars, transaction-cost-aware designs through w_current, and a switch from compounded to uncompounded returns in the Sharpe and annualized return calculations. Since then the package has moved only when a dependency forced it, and even then only far enough to keep the tests green.
◆ Prediction
Nothing in the entries suggests planned work; the next release is most likely triggered by another dependency change, on the same four-year-gap pattern.
