Documented vs supported

Documented: “sacral decubitus ulcer” · L89.159 Pressure ulcer of sacral region, unspecified stage
Criteria support: Pressure injury of sacral region, stage 2 · L89.152 Pressure ulcer of sacral region, stage 2
Outcome: Wound nurse documents stage 2, sacral
Rule: Pressure injury stage (sacral region) v2026.11-1
Published source: NPIAP Pressure Injury Stages (revised staging system) (2016), Stage 1-4, unstageable, deep tissue pressure injury definitions · source (checked 2026-11-14)

Effect if the clinician agrees (illustrative)

Change: L89.159 -> L89.152
Secondary-diagnosis level: non-CC → non-CC
MS-DRG (illustrative): 871 Septicemia or severe sepsis without MV >96 hours with MCC → 871 Septicemia or severe sepsis without MV >96 hours with MCC
Relative weight: 1.9425 → 1.9425 (+0.0000)
Codes before: A41.9, J18.9, R09.02, L89.159, K21.9, E11.9, I10
Codes after: A41.9, J18.9, R09.02, K21.9, E11.9, I10, L89.152

All open gaps on this encounter together: MS-DRG 871 → 871 (RW +0.0000). The grouping does not change; the record becomes accurate.

CC/MCC status, CC exclusions (subset) and relative weights from the public CMS FY2026 IPPS final rule tables (5, 6I, 6J, 6K). This is not a grouper and not a payment estimate. Queries never mention any of this.
