H05.0 — Acute inflammation of orbit
Is H05.0 billable?
No — H05.0 is a non-billable header code. H05.0 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 17 billable codes beneath H05.0.

Excludes1 — never code together — inherited from H05
The conditions below can never be reported together with H05.0 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- congenital malformation of orbit (Q10.7)
Excludes2 — not included here — inherited from Chapter 7
The conditions below are not part of H05.0, but a patient may have both at the same time. When documentation supports it, H05.0 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 H05.0, but a patient may have both at the same time. When documentation supports it, H05.0 and the excluded code may both be reported.
What codes fall under H05.0? (5)
How long has H05.0 existed?
H05.0 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.
