Severity Level (INA-CBGs)
A severity level (I, II, or III) in INA-CBGs is the tier of clinical complexity assigned to a coded case that raises the reimbursement package: level I is without complication/comorbidity, level II with minor, and level III with major complication or comorbidity. The level is justified by documented secondary diagnoses, so when comorbidities are present but not documented and coded, the hospital is paid for a less complex — and lower-value — case than it actually delivered.
Severity is therefore won or lost in the clinical note: the comorbidities have to be captured and coded to support the level. This is the upstream documentation-quality problem Micromeet's Claim Readiness is built to address, with the clinician deciding what is clinically accurate. AI writes. Doctors decide.
