Nico Bellweather: Malnutrition
ENC-00130 · 72M · Hospital Medicine · admitted Tue Oct 27, 2026 08:56 PM · discharged Tue Nov 03, 2026 12:32 PM · attending Dr. Kenji Stavros · resident Dr. Camila Oyelaran
Clinical validation gap Criteria met Open
Documented “severe protein-calorie malnutrition” (E43) conflicts with what the criteria support (Moderate (non-severe) protein-calorie malnutrition (acute illness context), E44.0).
Documented vs supported
- Documented
- “severe protein-calorie malnutrition” · E43 Unspecified severe protein-calorie malnutrition
- Criteria support
- Moderate (non-severe) protein-calorie malnutrition (acute illness context) · E44.0 Moderate protein-calorie malnutrition
- Outcome
- 3 moderate-or-worse characteristics, fewer than two severe (acute 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
- E43 -> E44.0
- Secondary-diagnosis level
- MCC → CC
- MS-DRG (illustrative)
- 193 Simple pneumonia and pleurisy with MCC → 194 Simple pneumonia and pleurisy with CC
- Relative weight
- 1.3144 → 0.8059 (-0.5085)
- Codes before
- J18.9, E43, E78.5, I10, K21.9
- Codes after
- J18.9, E78.5, I10, K21.9, E44.0
All open gaps on this encounter together: MS-DRG 193 → 194 (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.
Severity documentation index change SIMULATED
-0.5 points
SIMULATED: Illustrative severity weights (MCC = 1.0, CC = 0.5, non-CC = 0) summed over secondary diagnoses; not a validated risk-adjustment model and not a measured effect.
