Ckd icd 9-cm classification

This document proposes revisions to ICD-9-CM codes for classifying chronic kidney disease (CKD). It outlines stages of CKD based on glomerular filtration rate and proteinuria levels. The current codes do not distinguish CKD from end-stage renal disease (ESRD) or capture disease severity. The proposed changes would add codes to classify CKD stages 1-5, indicate presence of proteinuria, and code for underlying etiologies. This enhanced classification system could help determine patient risk, guide treatment, and assess quality of care for CKD.
