eratosthenes vs medicalcoder: at a glance
What is eratosthenes?
eratosthenes spends 0.1.0 hardening inputs rather than adding chronology methods.
eratosthenes does Bayesian estimation of archaeological chronologies from relative sequences, absolute constraints and artifact assemblages. The 0.0.9 line built out the inference diagnostics — traceplots, histograms, batch-means MCSE reporting, displacement estimation — and then consolidated artifact probability-density estimation into a single gibbs_ad_type(). The 0.1.0 tag turns outward instead, adding validators for every user-supplied structure and replacing seq_check() with a more informative seq_diag().
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.

◆ Current state
eratosthenes does Bayesian estimation of archaeological chronologies from relative sequences, absolute constraints and artifact assemblages. The 0.0.9 line built out the inference diagnostics — traceplots, histograms, batch-means MCSE reporting, displacement estimation — and then consolidated artifact probability-density estimation into a single gibbs_ad_type(). The 0.1.0 tag turns outward instead, adding validators for every user-supplied structure and replacing seq_check() with a more informative seq_diag().
◆ Where it's heading
The package is moving from research code to something a non-author can run. Consolidating estimation behind one function, then wrapping every input class in a validator, are the two steps that make failures legible instead of cryptic, and the diagnostics added earlier serve the same end for the sampler itself. Nothing in the window changes the underlying model; the work is all about making it usable and its output checkable.
◆ Prediction
With inputs validated and diagnostics in place, the next release is more likely to extend the constraint or assemblage modelling than to keep reworking the interface, though the feed's three sparse tags give little to read a cadence from.

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.
