Q39.4 ICD-10-CM Code: Esophageal web

Billing Status: YES. This is a valid, specific, and billable ICD-10-CM reference.

Inpatient Payment Groups (MS-DRG)

Potential MS-DRG participation — not a DRG assignment.

MS-DRGs this diagnosis helps define, as principal or secondary, per the CMS ICD-10-CM/PCS MS-DRG Definitions Manual v43, Appendix B.

  • MS-DRG 368 — MAJOR ESOPHAGEAL DISORDERS WITH MCC (MDC 06)
  • MS-DRG 369 — MAJOR ESOPHAGEAL DISORDERS WITH CC (MDC 06)
  • MS-DRG 370 — MAJOR ESOPHAGEAL DISORDERS WITHOUT CC/MCC (MDC 06)

A diagnosis appearing in a group's logic does not by itself determine the DRG assigned to a stay; the grouper uses the full claim.

Code Overview

Esophageal web is a billable ICD-10-CM diagnosis code (Q39.4).

MedCoder summary Summary composed by MedCoder from this code's official ICD-10-CM record. The tabular instructional notes themselves appear verbatim below.

Indexed Clinical Terms (1)

Official source data — entries quoted as published, in the Index’s own lookup phrasing

Clinical term phrases from the official ICD-10-CM Index to Diseases and Injuries that map to this code. These are alphabetic-index entries shown as the Index writes them — lookup phrasing, not necessarily the wording of a final diagnosis.

Verify Before Coding

  • MCC as a secondary diagnosis (FY2026). Can raise the stay's MS-DRG severity tier.

MS-DRG Grouper Relationships (FY2026)

Potential MS-DRG participation — not a DRG assignment.

FY2026 MS-DRG: MCC — Major Complication or Comorbidity. Reported as a secondary diagnosis, this code raises the stay's MS-DRG severity tier — except when the principal diagnosis is one of 11 clinically related codes on its CMS exclusion list.

Named in the grouper logic of 3 MS-DRGs: DRG 368 (MDC 06), DRG 369 (MDC 06), DRG 370 (MDC 06).

From the CMS MS-DRG Definitions Manual (Appendices B and C). Actual DRG assignment depends on the complete claim.

Related Codes

Same clinical process (MS-DRG)

Acts as MCC — raises the severity of other admissions. CMS groups these diagnoses into one MS-DRG principal-diagnosis exclusion process — a CC/MCC on this list never raises severity when the principal diagnosis is also on it.

Q39.0 — Atresia of esophagus without fistula, Q39.1 — Atresia of esophagus with tracheo-esophageal fistula, Q39.2 — Congenital tracheo-esophageal fistula without atresia, Q39.3 — Congenital stenosis and stricture of esophagus, Q39.5 — Congenital dilatation of esophagus, Q39.6 — Congenital diverticulum of esophagus, Q39.8 — Other congenital malformations of esophagus, Q39.9 — Congenital malformation of esophagus, unspecified, Q45.8 — Other specified congenital malformations of digestive system, Q45.9 — Congenital malformation of digestive system, unspecified

Same clinical category (CCSR)

AHRQ's Clinical Classifications Software groups these diagnoses under the same clinical category (Digestive congenital anomalies).

Same Index main term, other category

The ICD-10-CM Index to Diseases and Injuries files this code under the main term “Web, webbed”; these codes share that main term but sit in a different category of the Tabular List.

D50.1 — Sideropenic dysphagia (Paterson-Kelly), Q18.3 — Webbing of neck (neck), Q31.0 — Web of larynx (larynx), Q43.8 — Other specified congenital malformations of intestine (duodenal), Q70.1 — Webbed fingers (fingers), Q70.3 — Webbed toes (toes), Q87.89 — Other specified congenital malformation syndromes, not elsewhere classified (popliteal syndrome)
