Viggo Elsworth: Malnutrition

ENC-00079 · 75F · Hospital Medicine · admitted Sat Oct 31, 2026 01:16 PM · discharged Fri Nov 06, 2026 04:29 PM · attending Dr. Odette Galloway · resident Dr. Camila Oyelaran

Specificity gap Criteria met Open

Documented “malnutrition” (E46); criteria support the more specific Severe protein-calorie malnutrition (chronic illness context) (E43).

Documented vs supported

Documented
“malnutrition” · E46 Unspecified protein-calorie malnutrition
Criteria support
Severe protein-calorie malnutrition (chronic illness context) · E43 Unspecified severe protein-calorie malnutrition
Outcome
3 severe characteristics (chronic illness context)
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
E46 -> E43
Secondary-diagnosis level
CC → MCC
MS-DRG (illustrative)
194 Simple pneumonia and pleurisy with CC → 193 Simple pneumonia and pleurisy with MCC
Relative weight
0.8059 → 1.3144 (+0.5085)
Codes before
J18.9, E46, N28.9, E87.1, D64.9
Codes after
J18.9, N28.9, E87.1, D64.9, E43

All open gaps on this encounter together: MS-DRG 194 → 193 (RW +0.5085).

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.
