H16.14 ICD-10-CM Code: Punctate keratitis

Coder workflow for H16.14

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

Before you code H16.14

1. H16.14 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).

   ReviewH16.141, H16.142, H16.143, H16.149

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

Choose the right path

1. Does the documentation support one of the more specific codes beneath H16.14?
   Yes → Select that code and continue the checks below on its own page.
   No → H16.14 cannot be reported as written; query for the specificity its subcategory needs.

   ReviewH16.141, H16.142, H16.143, H16.149

Consider H16.14. 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).

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 H16.14 — 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.

  Overlapping diagnoses in the same category.

  Overlapping codes in the same category — the documentation decides which is the more specific fit.

  What moves you there: A record that documents no more than “Unspecified superficial keratitis” takes H16.10; specificity in the record moves it back here.

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 H16.14 or its code family, from the CMS ICD-10-CM Index to Diseases and Injuries.

Referenced by 1 Index etiology/manifestation pair: A30.9 — Leprosy, unspecified.

The ICD-10-CM Index lists these etiology codes with this code in brackets — the manifestation, reported second.

Related Codes

Same Index main term, other category

The ICD-10-CM Index to Diseases and Injuries files this code under the main term “Keratitis”; these codes share that main term but sit in a different category of the Tabular List.
