The UHDDS defines principal diagnosis as the condition established after study to be chiefly responsible for occasioning the admission of the patient to the hospital for care. That means the principal diagnosis is not always the condition that brought the patient into the hospital.
Inpatient coders will see an entirely new coding system October 1 when they begin officially using ICD-10-PCS. However, MS-DRGs are not changing. The only thing that is changing is what codes map to a particular MS-DRG.
These sample queries were adapted from The CDI Specialist’s Guide to ICD-10, created and donated by Cheryl Ericson, MS, RN, CCDS, CDIP, AHIMA-Approved ICD-10-CM/PCS Trainer, CDI education director at HCPro in Danvers, Mass.
Whether you work in a dedicated children’s hospital or a general hospital with a pediatric service line, you will likely come into contact with coding charts of kids. Sometimes they are easy (e.g., an inguinal hernia repair without obstruction or gangrene is an inguinal hernia repair without obstruction or gangrene—except it has to be identified as right or left in ICD-10). Sometimes they are not so easy (e.g., complex congenital diseases and their manifestations and complications).
