H01.009 — Unspecified blepharitis unspecified eye, unspecified eyelid

BillableUnspecified

Is H01.009 billable?

Yes, but H01.009 is an unspecified code. H01.009 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, H01.009 is an unspecified or catch-all code. Payers apply additional scrutiny to unspecified codes and many deny them when the medical record supports a more specific option, so check the documentation before selecting H01.009 — the more specific alternatives are listed below.

How is H01.009 listed in the Alphabetic Index?

These are the routes through the Alphabetic Index that lead to H01.009. They show the wording a clinician may have documented, which often differs from the Tabular description.

  • Blepharitis (angularis) (ciliaris) (eyelid) (marginal) (nonulcerative)

Excludes1 — never code together — inherited from H01.0

The conditions below can never be reported together with H01.009 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 H01.009, but a patient may have both at the same time. When documentation supports it, H01.009 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)
  • congenital malformations, deformations, and chromosomal abnormalities (Q00-Q99)
  • diabetes mellitus related eye conditions (E09.3-, E10.3-, E11.3-, E13.3-)
  • endocrine, nutritional and metabolic diseases (E00-E88)
  • injury (trauma) of eye and orbit (S05.-)
  • injury, poisoning and certain other consequences of external causes (S00-T88)
  • neoplasms (C00-D49)
  • symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (R00-R94)
  • syphilis related eye disorders (A50.01, A50.3-, A51.43, A52.71)

Excludes2 — not included here — inherited from H00-H05

The conditions below are not part of H01.009, but a patient may have both at the same time. When documentation supports it, H01.009 and the excluded code may both be reported.

How long has H01.009 existed?

Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
