ICD-10 Coding in Home Health
ICD-10 coding in home health is the assignment of diagnosis codes to each patient's episode, reported on the OASIS and the claim. Under PDGM, the principal diagnosis sets the clinical grouping and secondary diagnoses set the comorbidity adjustment, so coding accuracy directly determines payment, audit exposure, and how patient complexity appears in quality data.
