It sits at the top of its hierarchy: no other condition category supersedes it.
RAF Weight by Payment Segment 7 segments
| Payment Segment | Relative Factor |
|---|---|
| Community, non-dual, aged | 1.692 |
| Community, partial-benefit dual, aged | 1.149 |
| Community, full-benefit dual, aged | 0.957 |
| Community, non-dual, disabled | 1.427 |

A beneficiary is scored in exactly one segment, set by Medicaid (dual) status, aged or disabled entitlement, and residence. Factors are relative weights, not dollar amounts; new-enrollee segments score on demographics only. HCC 193 neither supersedes nor is superseded by any other category, so it always counts alongside unrelated HCCs.
