Installation

From PyPI

pip install msdrg

uv add msdrg

Prebuilt wheels are available for:

Platform Architecture
Linux x86_64, aarch64
macOS x86_64, Apple Silicon (aarch64)
Windows x86_64

Note

Prebuilt wheels include the compiled Zig shared library — you do not need Zig installed to use pip install msdrg.

From source

Building from source requires Zig 0.16+ at build time. Install from ziglang.org/download and make sure zig is on your PATH.

git clone https://github.com/Bedrock-Billing/mz-drg.git
cd mz-drg

python3 -m venv .venv
source .venv/bin/activate
pip install -e .

Alternatively, set the ZIG environment variable to a custom path:

export ZIG=/path/to/zig
pip install -e .

Verify installation

python -c "import msdrg; print(msdrg.__version__)"
# Expected: 0.1.3 (or current version)

>>> import msdrg
>>> dir(msdrg)
['ClaimInput', 'DiagnosisInput', 'DiagnosisOutput', 'GroupResult',
 'MceDiagnosisInput', 'MceEditDetail', 'MceEditor', 'MceInput',
 'MceProcedureInput', 'MceResult', 'MsdrgGrouper', 'ProcedureInput',
 'ProcedureOutput', 'create_claim', 'create_mce_input', ...]

Troubleshooting

ImportError: shared library not found

The prebuilt wheel may not exist for your platform. Install from source (requires Zig 0.16+): 

pip install msdrg --no-binary msdrg

Zig compilation fails during install

Make sure you have Zig 0.16 or newer. Older versions are not compatible. 

zig version  # should be 0.16.x or higher

Data directory not found

The binary data files should be bundled with the package. If installing in development mode (pip install -e .), verify that data/bin/ exists and contains .bin files.
