Quinn Northam: Obesity

ENC-00164 · 79F · Pulmonology · admitted Fri Oct 30, 2026 08:03 AM · discharged Sat Nov 07, 2026 10:10 AM · attending Dr. Kenji Stavros

Specificity gap Criteria met Open Model draft failed the query linter: edit before sending

Documented “obesity” (E66.9); criteria support the more specific Obesity, class 1 (E66.811).

Documented vs supported

Documented: “obesity” · E66.9 Obesity, unspecified
Criteria support: Obesity, class 1 · E66.811 Obesity, class 1
Outcome: BMI 31.5 (class 1)
Rule: Obesity class from BMI v2026.11-1
Published source: CDC: Adult BMI Categories (2024), Class 1: 30 to <35; class 2: 35 to <40; class 3: 40 or higher (adults aged 20 and over) · source (checked 2026-11-14)

Effect if the clinician agrees (illustrative)

Change: E66.9 -> E66.811
Secondary-diagnosis level: non-CC → non-CC
MS-DRG (illustrative): 191 Chronic obstructive pulmonary disease with CC → 191 Chronic obstructive pulmonary disease with CC
Relative weight: 0.8430 → 0.8430 (+0.0000)
Codes before: J44.1, E66.9, I50.20, D64.9, L89.150, E11.9, E78.5
Codes after: J44.1, I50.20, D64.9, L89.150, E11.9, E78.5, E66.811, Z68.31

All open gaps on this encounter together: MS-DRG 191 → 191 (RW +0.0000). The grouping does not change; the record becomes accurate.

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.

0.0 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.
