H01.8 ICD-10-CM Code: Other specified inflammations of eyelid

Coder workflow for H01.8

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

Before you code H01.8

1. H01.8 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).

   ReviewH01.81, H01.82, H01.83, H01.84, H01.85, H01.86, H01.89, H01.8A, H01.8B

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

2. “Other” (NEC) means the condition is specified in the record but no dedicated code captures it. Confirm the documented form is not one a sibling code names before settling on H01.8; if the record states no specifics at all, the unspecified sibling applies instead. “Other” codes are for documented conditions the classification gives no specific code; “unspecified” codes are for records lacking the detail (Guidelines I.A.9.a, I.A.9.b).

   See the relationships section · Guide: Other vs unspecified (NEC vs NOS) →

Choose the right path

1. Does the documentation support one of the more specific codes beneath H01.8?
   Yes → Select that code and continue the checks below on its own page.
   No → H01.8 cannot be reported as written; query for the specificity its subcategory needs.

   ReviewH01.81, H01.82, H01.83, H01.84, H01.85, H01.86, H01.89, H01.8A, H01.8B

Consider H01.8. Then review the Code Also 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).

Any detail beyond this code’s title

What the record states that a more specific sibling code would capture — or its absence, which itself supports the unspecified code.

Official instructions as workflow

• Excludes2 — not part of H01.8(2 notes)

  Coding workflow: The conditions named in this note are not included in H01.8. When the record documents both, both may be reported; the note is a boundary, not a prohibition.

  CompareS01.1, S00.1, S00.2

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

• Code Also — related condition(1 note)

  Coding workflow: Review the related condition when both are documented and the instruction applies. A Code Also note does not fix sequencing; the order follows the circumstances of the encounter.

  ReviewB88.01

  See the official tabular notes · Guidelines I.A.17

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.

MedCoder analysis — pairs from this code’s official notes, distinctions written by MedCoder

The codes most likely to be picked instead of H01.8 — named in its own official notes, or sharing its laterality or encounter family — with what separates them and which documentation moves the case. Each links to the full comparison.

• S01.1— Excludes2 relationship (Informational)

  Distinct conditions — both may be reported.

  A distinct condition — both may be reported when both are documented.

  What moves you there: Documentation of open wound of eyelid adds S01.1; it is not part of this code and both may be reported when both are documented.

• S00.1— Excludes2 relationship (Informational)

  Distinct conditions — both may be reported.

  A distinct condition — both may be reported when both are documented.

  What moves you there: Documentation of superficial injury of eyelid adds S00.1; it is not part of this code and both may be reported when both are documented.

• S00.2— Excludes2 relationship (Informational)

  Distinct conditions — both may be reported.

  A distinct condition — both may be reported when both are documented.

Relationships are read from this code's own official notes, its laterality siblings and its encounter family; the wording of each distinction is MedCoder editorial, and the documentation named in each “what moves you there” line is the official note phrase or sibling title itself.

Relationships & Classification

MedCoder structured relationships — computed from published CMS and AHRQ datasets

Other codes that name H01.8 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 Use Additional Code instruction: L51 — Erythema multiforme.

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

Referenced by 1 Code Also instruction: B88.01 — Infestation by Demodex mites.

These codes suggest coding this condition alongside when both are present.
