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 820 — LYMPHOMA AND LEUKEMIA WITH MAJOR O.R. PROCEDURES WITH MCC (MDC 17)
  • MS-DRG 821 — LYMPHOMA AND LEUKEMIA WITH MAJOR O.R. PROCEDURES WITH CC (MDC 17)
  • MS-DRG 822 — LYMPHOMA AND LEUKEMIA WITH MAJOR O.R. PROCEDURES WITHOUT CC/MCC (MDC 17)
  • MS-DRG 823 — LYMPHOMA AND NON-ACUTE LEUKEMIA WITH OTHER PROCEDURES WITH MCC (MDC 17)
  • MS-DRG 824 — LYMPHOMA AND NON-ACUTE LEUKEMIA WITH OTHER PROCEDURES WITH CC (MDC 17)
  • MS-DRG 825 — LYMPHOMA AND NON-ACUTE LEUKEMIA WITH OTHER PROCEDURES WITHOUT CC/MCC (MDC 17)
  • MS-DRG 840 — LYMPHOMA AND NON-ACUTE LEUKEMIA WITH MCC (MDC 17)
  • MS-DRG 841 — LYMPHOMA AND NON-ACUTE LEUKEMIA WITH CC (MDC 17)
  • MS-DRG 842 — LYMPHOMA AND NON-ACUTE LEUKEMIA WITHOUT CC/MCC (MDC 17)

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.

Coding instructions

Official Tabular Instructional Notes: the inclusion, exclusion and sequencing notes published for D89.1 in the official ICD-10-CM tabular list, quoted as published.

Source: CMS/CDC — ICD-10-CM Tabular ListRelease: FY2026Effective: October 1, 2025

Notes without a marker are published on D89.1 itself; “inherited from” names the category or block whose note applies here.

This page already reflects the FY2027 tabular note taking effect October 1, 2026.

Includes

Conditions the official ICD-10-CM tabular list includes under this code.

  • defects in the complement system
  • immunodeficiency disorders, except human immunodeficiency virus [HIV] disease
  • sarcoidosis

Source: inherited from D80-D89

Inclusion Terms

Alternative terms the tabular list files under this code.

  • Cryoglobulinemic purpura
  • Cryoglobulinemic vasculitis
  • Essential cryoglobulinemia
  • Idiopathic cryoglobulinemia
  • Mixed cryoglobulinemia
  • Primary cryoglobulinemia
  • Secondary cryoglobulinemia

Excludes1 — Not Coded Here

Conditions generally not reported together with this code (Excludes1) -- an error unless the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).

Excludes2 — Not Included Here

Conditions not covered by this code, but which may be reported alongside it when both are present.

Coder workflow for D89.1

MedCoder structured workflow — derived from this code’s own official record

Before you code D89.1

  1. Check the Excludes1 note: if the documentation supports a condition named there, do not simply proceed with D89.1. Excludes1 conditions are not reported together with this code unless the record shows they are unrelated (Guidelines I.A.12.a).

    See the official tabular notes

Choose the right path

  1. Does the documentation support a condition named in D89.1’s Excludes1 note?
    Yes → Do not simply proceed: review the excluded code. Both are reported only when the record shows the two conditions are unrelated.
    No → Continue.

    ReviewR77.1, D47.2, M35.9, D71

Consider D89.1. Then confirm the code is valid for the date of service in the Verify section.

Documentation check

The provider’s diagnostic statement
Codes are assigned from the provider’s documented diagnosis, not from clinical criteria, test values or a medication list (Guidelines I.A.19).

Official instructions as workflow

  • Excludes1 — check before selecting D89.1(4 notes)

    Coding workflow: If the documentation supports a condition named in this note, do not simply proceed with D89.1: the two are not reported together. The one exception is when the record shows the two conditions are unrelated to each other.

    CompareR77.1, D47.2, M35.9, D71

    See the official tabular notes · Guidelines I.A.12.a

  • Excludes2 — not part of D89.1(2 notes)

    Coding workflow: The conditions named in this note are not included in D89.1. When the record documents both, both may be reported; the note is a boundary, not a prohibition.

Coding decision scenarios

Pattern scenarios for this code’s structure — decision rules, not clinical cases

Documentation: Both the condition D89.1 describes and a condition named in its Excludes1 note are documented for the same encounter.

Coding question: Can both codes be reported?

Path: Review the Excludes1 note and the excluded code, and look for a provider statement on whether the two conditions are related.

Reason: Excludes1 means the two are not coded together; the exception is when the record shows the conditions are unrelated to each other (Guidelines I.A.12.a).

ReviewR77.1, D47.2, M35.9, D71

Every row is derived from this code’s own record — its title, tabular notes, 7th-character family and same-category siblings — with fixed MedCoder wording; nothing is inferred about a patient. The official notes and guideline text are in the sections each row links to, and they control.

Code Overview

Cryoglobulinemia is a billable ICD-10-CM diagnosis code (D89.1).

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 (9)

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)

Reserved for future guideline expansion

Relationships & Classification

MedCoder structured relationships — computed from published CMS and AHRQ datasets

Other codes that name D89.1 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 2 Excludes1 notes: D69 — Purpura and other hemorrhagic conditions, D72 — Other disorders of white blood cells (via D89.-).

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

Referenced by 3 Code First instructions across 2 chapters: J99 — Respiratory disorders in diseases classified elsewhere, N08 — Glomerular disorders in diseases classified elsewhere, N16 — Renal tubulo-interstitial disorders in diseases classified elsewhere.

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 9 MS-DRGs: DRG 820 (MDC 17), DRG 821 (MDC 17), DRG 822 (MDC 17), DRG 823 (MDC 17), DRG 824 (MDC 17), DRG 825 (MDC 17), DRG 840 (MDC 17), DRG 841 (MDC 17), DRG 842 (MDC 17).

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