Nico Ravensworth: Malnutrition

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 not met Open

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): 291 Heart failure and shock with MCC → 291 Heart failure and shock with MCC
Relative weight: 1.2838 → 1.2838 (+0.0000)
Codes before: I50.9, E46, E87.1, D64.9, L89.154
Codes after: I50.9, E87.1, D64.9, L89.154

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.

Question:
The nutrition indicators above are documented in this encounter. Could you clarify the status and severity of the documented nutritional diagnosis?

Response options (select one or write your own):
( ) Malnourished: confirmed (please document the supporting clinical information)
( ) Malnourished: ruled out
( ) Other explanation of the clinical findings (please specify): ____________
( ) Unable to determine

Please respond based on your independent clinical judgement. Any response, including "unable to determine", is acceptable. This query and your response are kept as part of the health record.

Other findings on this encounter

Heart failure · Clinical judgement required Clinical judgement required: LVEF 46% (HFmrEF, 41-49%); the type wording and its coding convention need the clinician.
Hyponatraemia · Clinical validation gap Documented “hyponatremia” (E87.1) but the criteria are not met: All sodium values 135 or above (lowest 136).
Pressure injury · Clinical validation gap Documented “stage 4 sacral pressure ulcer” (L89.154) conflicts with what the criteria support (Pressure injury of sacral region, stage 2, L89.152).
