When may an inpatient case qualify for an additional IPPS outlier payment beyond the base MS-DRG amount?
Select an answer to reveal the explanation.
Short Explanation
Outliers are the safety valve for the rare, extraordinarily expensive inpatient stay. It’s not “any MCC” or “stayed four days”—it’s costs blowing past a set threshold. Base DRG first; outlier on top only when the math qualifies.
Full Explanation
IPPS outlier payments provide additional reimbursement when an inpatient case’s costs exceed a regulatory threshold relative to the DRG payment. Coding an MCC, modest LOS, or secondary insurance alone does not create outlier eligibility. Coders should understand outliers as a payment-methodology feature separate from base MS-DRG assignment.
