H01.00 — Unspecified blepharitis
Is H01.00 billable?
No — H01.00 is a non-billable header code. H01.00 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 9 billable codes beneath H01.00.

Excludes1 — never code together — inherited from H01.0
The conditions below can never be reported together with H01.00 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- blepharoconjunctivitis (H10.5-)
Excludes2 — not included here — inherited from Chapter 7
The conditions below are not part of H01.00, but a patient may have both at the same time. When documentation supports it, H01.00 and the excluded code may both be reported.
- certain conditions originating in the perinatal period (P04-P96)
- certain infectious and parasitic diseases (A00-B99)
- complications of pregnancy, childbirth and the puerperium (O00-O9A)

How long has H01.00 existed?
H01.00 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
