DRG & Inpatient Claims Audit
MS-DRG validation, principal diagnosis selection, and CC/MCC capture reviewed against the physician record.
The complex MS-DRG rules, changing payer policies, clinical documentation requirements, value-based reimbursement models, and strict payer audits are all driving a reaction from hospitals and health systems that will put these providers under greater reimbursement pressure in 2026.
