Coding instructions

Official Tabular Instructional Notes: the inclusion, exclusion and sequencing notes published for J68 in the official ICD-10-CM tabular list, quoted as published.

Notes without a marker are published on J68 itself; “inherited from” names the category or block whose note applies here.

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

Code First

Underlying conditions that must be sequenced before this code.

Use Additional Code

Supplementary codes the tabular list directs you to add.

  • Use additional code to identify associated respiratory conditions, such as:
  • acute respiratory failure (J96.0-)

Coder workflow for J68

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

Before you code J68

  1. J68 is not reportable as written. Select the more specific code beneath it that the documentation supports. Codes are reported to the highest level of specificity the classification provides (Guidelines I.B.2).

    ReviewJ68.0, J68.1, J68.2, J68.3, J68.4, J68.8, J68.9

    See the relationships section · Guide: How to choose an ICD-10-CM code →

  2. J68’s title joins a condition with an associated condition or complication. Confirm each component is documented. Where the classification presumes the link through the “with” convention, only a provider statement that the conditions are unrelated defeats it. A combination code is assigned only when it fully identifies the documented conditions; a required second code for the stage, type or manifestation is still reported when the notes ask for it (Guidelines I.B.9, I.A.15).

    Guide: Combination codes →

Choose the right path

  1. Does the documentation support one of the more specific codes beneath J68?
    Yes → Select that code and continue the checks below on its own page.
    No → J68 cannot be reported as written; query for the specificity its subcategory needs.

    ReviewJ68.0, J68.1, J68.2, J68.3, J68.4, J68.8, J68.9

  2. Is the underlying (etiologic) condition the Code First note names documented?
    Yes → Sequence the underlying condition first, then J68.
    No → Continue; do not add an underlying condition the record does not document.

Consider J68. Then work the Use Additional Code note, and 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).
The associated condition or complication
Whether the associated condition the title names is documented; the “with” convention presumes some links, and a provider statement that the conditions are unrelated defeats it (Guidelines I.A.15).
The underlying (etiologic) condition
Named in the Code First note; sequenced before this code when documented (Guidelines I.A.13).
The conditions the Use Additional Code note names
Reported with this code when documented; a conditional instruction (“if applicable”, “if known”) applies only when the record supports it.

Official instructions as workflow

  • Excludes2 — not part of J68(2 notes)

    Coding workflow: The conditions named in this note are not included in J68. 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

  • Code First — sequencing check(1 note)

    Coding workflow: Check whether the underlying or etiologic condition the note names is documented. When it is, sequence it before J68. Do not add an underlying condition the record does not document.

    See the official tabular notes · Guidelines I.A.13

  • Use Additional Code — after identifying J68(2 notes)

    Coding workflow: Check whether the documentation supports the additional code(s) the note names, and report them with J68 when it does. Where the instruction is conditional (“if applicable”, “if known”), it applies only when the record documents the condition.

Coding decision scenarios

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

Documentation: Only one of the components this code’s title joins is documented.

Coding question: Is J68 supported?

Path: Review the code for the documented component on its own.

Reason: A combination code is assigned only when it fully identifies the documented conditions; otherwise the documented component takes its own code (Guidelines I.B.9).

Documentation: The underlying condition the Code First note names is documented alongside this condition.

Coding question: How are the two sequenced?

Path: Review the Code First note.

Reason: The underlying condition is sequenced first and the manifestation follows (Guidelines I.A.13).

Documentation: A condition the Use Additional Code note names is documented.

Coding question: Is a second code reported with J68?

Path: Review the Use Additional Code note and the code it names.

Reason: The additional code is reported when the record documents the condition; a conditional instruction applies only when its condition is met (Guidelines I.A.13).

Code Overview

Respiratory conditions due to inhalation of chemicals, gases, fumes and vapors is a non-billable ICD-10-CM category code (J68). A more specific billable subcode must be selected for claims submission.

Decision Points

The directives on this code's own record, as a pre-claim checklist.

  1. Sequencing: 1 Code First instruction — the underlying condition is sequenced before this code when present. See the Code First notes
  2. 2 Use Additional Code instructions — report the named additional code(s) when the documentation supports them. See the Use Additional Code notes
  3. 2 Excludes2 entries — those conditions are not part of this code and may be reported additionally when documented. See the Excludes2 notes

Checklist rows are derived from this code's own official directives; the wording of each check is MedCoder editorial. The official notes themselves are in the sections each row links to.

Relationships & Classification

MedCoder structured relationships — computed from published CMS and AHRQ datasets

Other codes that name J68 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 1 Excludes1 note: J81 — Pulmonary edema.

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

Referenced by 5 Excludes2 notes: J18 — Pneumonia, unspecified organism, J44.1 — Chronic obstructive pulmonary disease with (acute) exacerbation, J44.9 — Chronic obstructive pulmonary disease, unspecified, J45.909 — Unspecified asthma, uncomplicated, J84 — Other interstitial pulmonary diseases.

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.

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

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