Zara Whitlock: Malnutrition

ENC-00017 · 70M · Pulmonology · admitted Sun Nov 08, 2026 05:21 PM · in hospital · attending Dr. Kenji Stavros · resident Dr. Noor Halvorsen

Clinical validation gap Criteria not met Open In hospital: concurrent review Resident note awaiting attending cosign

Documented “malnourished” (E46) but the criteria are not met: 4 characteristics assessed and none met.

Documented vs supported

Documented: “malnourished” · E46 Unspecified protein-calorie malnutrition
Criteria support: criteria not met
Outcome: 4 characteristics assessed and none met
Rule: Malnutrition severity (ASPEN/Academy 2012 consensus characteristics) v2026.11-1
Published source: Consensus statement: Academy of Nutrition and Dietetics and ASPEN: characteristics recommended for the identification and documentation of adult malnutrition (White JV et al., J Acad Nutr Diet 2012;112:730-738) (2012), Table: clinical characteristics; at least two of six characteristics; acute illness and chronic illness contexts · source (checked 2026-11-14)
Contested: GLIM (2019) is an alternative, internationally endorsed framework with different thresholds; an organization must choose one per policy. This rule encodes ASPEN/Academy 2012 and lists GLIM as the alternative.

Effect if the clinician agrees (illustrative)

Change: remove E46
Secondary-diagnosis level: CC → removed
MS-DRG (illustrative): 191 Chronic obstructive pulmonary disease with CC → 192 Chronic obstructive pulmonary disease without CC/MCC
Relative weight: 0.8430 → 0.6420 (-0.2010)
Codes before: J44.1, E46, I50.9, L89.159, E78.5, I10
Codes after: J44.1, I50.9, L89.159, E78.5, I10

All open gaps on this encounter together: MS-DRG 191 → 190 (RW +0.2647).

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.
