H40.6 — Glaucoma secondary to drugs

Not billable

Is H40.6 billable?

No — H40.6 is a non-billable header code. H40.6 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 20 billable codes beneath H40.6.

How is H40.6 listed in the Alphabetic Index?

These are the routes through the Alphabetic Index that lead to H40.6. They show the wording a clinician may have documented, which often differs from the Tabular description.

  • Glaucoma › secondary › drugs

Use additional code

Report an additional code alongside H40.6 to fully describe the condition. H40.6 is sequenced first.

  • code for adverse effect, if applicable, to identify drug (T36-T50 with fifth or sixth character 5)

Excludes1 — never code together — inherited from H40

The conditions below can never be reported together with H40.6 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • absolute glaucoma (H44.51-)
  • congenital glaucoma (Q15.0)
  • traumatic glaucoma due to birth injury (P15.3)

Excludes2 — not included here — inherited from Chapter 7

The conditions below are not part of H40.6, but a patient may have both at the same time. When documentation supports it, H40.6 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)

What codes fall under H40.6? (4)

How long has H40.6 existed?

H40.6 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.
