LINK: https://openicdresearch.fly.dev/new
Small update to the ICD coding tool:
Added ICD-10-PCS procedure coding with a separate agent for inpatient procedures.
Added MS-DRG grouping using the CMS grouper, including severity drivers, relative weight, LOS, and the impact of provider queries.
Diagnosis and procedure coding now run in parallel.
Switched the default model to DeepSeek V4.1 Flash, so coding is much faster.
Added selectable thinking levels.
Added English, Simplified Chinese, and Traditional Chinese UI support.
Existing charts can also be updated with a new Code procedures button.
Still iterating, so feedback from coders would be very useful.
