D50.1 ICD-10-CM Code: Sideropenic dysphagia

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

Coding at a Glance

Tabular directives
4 inclusion terms

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 811 — RED BLOOD CELL DISORDERS WITH MCC (MDC 16)
  • MS-DRG 812 — RED BLOOD CELL DISORDERS WITHOUT MCC (MDC 16)

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.

Notes without a marker are published on D50.1 itself; “inherited from” names the category or block whose note applies here.

Code Overview

Sideropenic dysphagia is a billable ICD-10-CM diagnosis code (D50.1).

Indexed Clinical Terms (13)

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.

Official Coding Guidelines

No excerpt in the ICD-10-CM Official Guidelines names this code specifically. Its chapter carries only this chapter-wide note:

Chapter 3: Disease of the blood and blood-forming organs and certain disorders involving the immune mechanism (D50-D89)

Relationships & Classification

MedCoder structured relationships — computed from published CMS and AHRQ datasets

Other codes that name D50.1 or its code family, from the CMS ICD-10-CM tabular instructional notes. Tabular-note edges are stored at the code family level that carries each note.

Referenced by 3 Excludes1 notes across 2 chapters: E61.1 — Iron deficiency (via D50.-), E83.1 — Disorders of iron metabolism (via D50.-), R71 — Abnormality of red blood cells (via D50.-).

These codes’ tabular lists mark this diagnosis as mutually exclusive — not reported together unless the conditions are documented as unrelated.

Referenced by 23 Excludes2 notes across 2 chapters: E40 — Kwashiorkor (via D50.-), E40-E46 — Malnutrition (E40-E46) (via D50.-), E41 — Nutritional marasmus (via D50.-), E42 — Marasmic kwashiorkor (via D50.-), E43 — Unspecified severe protein-calorie malnutrition (via D50.-), E44 — Protein-calorie malnutrition of moderate and mild degree (via D50.-), E45 — Retarded development following protein-calorie malnutrition (via D50.-), E46 — Unspecified protein-calorie malnutrition (via D50.-), E50 — Vitamin A deficiency (via D50.-), E50-E64 — Other nutritional deficiencies (E50-E64) (via D50.-), E51 — Thiamine deficiency (via D50.-), E52 — Niacin deficiency [pellagra] (via D50.-), E53 — Deficiency of other B group vitamins (via D50.-), E54 — Ascorbic acid deficiency (via D50.-), E55 — Vitamin D deficiency (via D50.-), E56 — Other vitamin deficiencies (via D50.-), E58 — Dietary calcium deficiency (via D50.-), E59 — Dietary selenium deficiency (via D50.-), E60 — Dietary zinc deficiency (via D50.-), E61 — Deficiency of other nutrient elements (via D50.-), +3 more.

These codes’ tabular lists name this diagnosis as distinct — both may be reported when both are documented.

Referenced by 2 Code First instructions across 2 chapters: I21.A1 — Myocardial infarction type 2 (via D50.-), M90.5 — Osteonecrosis in diseases classified elsewhere (via D50.-).

Each of these codes carries a Code First note naming this condition — when that code is reported, THIS code is sequenced first, ahead of it.

MS-DRG Grouper Relationships (FY2026)

Potential MS-DRG participation — not a DRG assignment.

FY2026 MS-DRG: not on the CMS CC/MCC list — as a secondary diagnosis this code does not change MS-DRG severity for that release.

Named in the grouper logic of 2 MS-DRGs: DRG 811 (MDC 16), DRG 812 (MDC 16).

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