Vaping code is in there too. The home health Patient-Driven Groupings Model grouper will contain the new diagnosis code for COVID-19, the Centers for Medicare & Medicaid Services confirms. The Centers for Disease Control and Prevention’s National Center for Health Statistics has implemented two new ICD-10-CM diagnosis codes, effective April 1, CMS explains on its PDGM billing webpage: U07.1 for COVID-19 and U07.0 for Vaping-related disorders. Case mix: CMS is assigning both codes to the Medication Management, Teaching and Assessment-Respiratory (MMTA-Respiratory) clinical group for case-mix adjustment under PDGM, it says.“Additionally, U07.1, COVID-19, will be added to a new comorbidity subgroup, Respiratory 10, and will receive the Low Comorbidity adjustment under the HH PPS case-mix system,” CMS adds. Grouper: The groups for both codes “will be included in the Home Health Patient-Driven Groupings Model (HH PDGM) Grouper software package, v01.1.20,” CMS continues. The updated Grouper is effective for home health claims with “From” dates on or after April 1, CMS says at www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/HomeHealthPPS/HH-PDGM.
