ENC-00043 · 86F · Cardiology · admitted Thu Oct 29, 2026 08:52 AM · discharged Thu Nov 05, 2026 12:42 PM · attending Dr. Jalen Carrow · resident Dr. Greta Kowalczyk

Clinical validation gap Criteria met Open

Documented “stage 4 sacral pressure ulcer” (L89.154) conflicts with what the criteria support (Pressure injury of sacral region, stage 2, L89.152).

Documented vs supported

Documented: “stage 4 sacral pressure ulcer” · L89.154 Pressure ulcer of sacral region, stage 4
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: L89.154 -> L89.152
Secondary-diagnosis level: MCC → non-CC
MS-DRG (illustrative): 291 Heart failure and shock with MCC → 292 Heart failure and shock with CC
Relative weight: 1.2838 → 0.8490 (-0.4348)
Codes before: I50.9, E46, E87.1, D64.9, L89.154
Codes after: I50.9, E46, E87.1, D64.9, L89.152

All open gaps on this encounter together: MS-DRG 291 → 293 (RW -0.7178).

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.
