J63.5 ICD-10-CM Code: Stannosis

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

Coding at a Glance

Tabular directives
1 Excludes1 · 2 Excludes2
Risk adjustment
CMS-HCC V28: 1 category · CMS-HCC V22 category 112

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 196 — INTERSTITIAL LUNG DISEASE WITH MCC (MDC 04)
  • MS-DRG 197 — INTERSTITIAL LUNG DISEASE WITH CC (MDC 04)
  • MS-DRG 198 — INTERSTITIAL LUNG DISEASE WITHOUT CC/MCC (MDC 04)

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.

Risk Adjustment (CMS-HCC)

Payment categories this diagnosis maps to under CMS-HCC V28, payment year 2026.

  • HCC 280 — Chronic Obstructive Pulmonary Disease, Interstitial Lung Disorders, and Other Chronic Lung Disorders

Other models: CMS-HCC V22 HCC 112

Risk scores depend on the enrollee's full accepted diagnosis set and segment; a category mapping alone does not determine payment.

Coding instructions

Official Tabular Instructional Notes: the inclusion, exclusion and sequencing notes published for J63.5 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 J63.5 itself; “inherited from” names the category or block whose note applies here.

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).

Source: inherited from J63

Excludes2 — Not Included Here

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

Source: inherited from J60-J70

Coder workflow for J63.5

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

Before you code J63.5

  1. Check the Excludes1 note: if the documentation supports a condition named there, do not simply proceed with J63.5. 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 J63.5’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.

    ReviewA15, J65

Consider J63.5. 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 J63.5(1 note)

    Coding workflow: If the documentation supports a condition named in this note, do not simply proceed with J63.5: the two are not reported together. The one exception is when the record shows the two conditions are unrelated to each other.

    CompareA15, J65

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

  • Excludes2 — not part of J63.5(2 notes)

    Coding workflow: The conditions named in this note are not included in J63.5. When the record documents both, both may be reported; the note is a boundary, not a prohibition.

    CompareJ45, C34

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

Coding decision scenarios

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

Documentation: Both the condition J63.5 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).

ReviewA15, J65

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.

Relationships & Classification

MedCoder structured relationships — computed from published CMS and AHRQ datasets

Other codes that name J63.5 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: J39.3 — Upper respiratory tract hypersensitivity reaction, site unspecified (via J63.-), J81 — Pulmonary edema (via J63.-).

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

Referenced by 4 Excludes2 notes: J44.1 — Chronic obstructive pulmonary disease with (acute) exacerbation (via J63.-), J44.9 — Chronic obstructive pulmonary disease, unspecified (via J63.-), J45.909 — Unspecified asthma, uncomplicated (via J63.-), J84 — Other interstitial pulmonary diseases (via J63.-).

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

Referenced by 1 Code First instruction: J84.170 — Interstitial lung disease with progressive fibrotic phenotype in diseases classified elsewhere (via J63.-).

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.

Referenced by 16 Use Additional Code instructions: T51 — Toxic effect of alcohol (via J63.-), T51-T65 — Toxic effects of substances chiefly nonmedicinal as to source (T51-T65) (via J63.-), T52 — Toxic effect of organic solvents (via J63.-), T53 — Toxic effect of halogen derivatives of aliphatic and aromatic hydrocarbons (via J63.-), T54 — Toxic effect of corrosive substances (via J63.-), T55 — Toxic effect of soaps and detergents (via J63.-), T56 — Toxic effect of metals (via J63.-), T57 — Toxic effect of other inorganic substances (via J63.-), T58 — Toxic effect of carbon monoxide (via J63.-), T59 — Toxic effect of other gases, fumes and vapors (via J63.-), T60 — Toxic effect of pesticides (via J63.-), T61 — Toxic effect of noxious substances eaten as seafood (via J63.-), T62 — Toxic effect of other noxious substances eaten as food (via J63.-), T63 — Toxic effect of contact with venomous animals and plants (via J63.-), T64 — Toxic effect of aflatoxin and other mycotoxin food contaminants (via J63.-), T65 — Toxic effect of other and unspecified substances (via J63.-).

These codes instruct coders to additionally report this code when it applies.

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 3 MS-DRGs: DRG 196 (MDC 04), DRG 197 (MDC 04), DRG 198 (MDC 04).

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