  1. Coding for AR-DRG analysis and funding Linda Best 14.00 - 14.45 Tuesday, 6th December 2011

  2. What are coded data used for? Many uses, including: Casemix, diagnosis related groups (DRGs) Research National morbidity statistics Health services planning and evaluation Quality assurance activities Epidemiology

  3. The building blocks • ICD-10-AM and ACHI codes are the building blocks of AR-DRGs used in many settings as health care funding mechanisms. • The principal diagnosis, additional diagnoses and interventions, as documented in the clinical record, are converted into ICD-10-AM and ACHI codes. These codes are then used in the grouping process.

  4. Calculatingan AR-DRG: Data Items Required ICD-10-AM/ACHI Codes • Principal diagnosis • Additional diagnoses, such as complications and comorbidities • Procedure/s Sex Length Of Stay • Or Admission and Separation Dates Same-day Status Mode of separation (discharge status) • Includes died, transferred Newborn admission weight • For age 28 days or less, plus older if less than 2500 grams

  5. If it’s not written, it didn’t happen! • The production of quality clinical data is a collaborative effort • Channels of communication between clinicians and clinical coders should be open and frequently used • Quality documentation supports quality coding which results in appropriate AR-DRG allocation

  6. Good clinical documentation The most appropriate AR-DRG can only be assigned to an episode of patient care when relevant clinical information is accurately documented in the clinical record

  7. Good clinical documentation cont. • Need clear and complete documentation • Important for clinical specialties to understand what information can impact on DRG assignment

  8.
