H26.21 — Cataract with neovascularization
Is H26.21 billable?
No — H26.21 is a non-billable header code. H26.21 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 4 billable codes beneath H26.21.

How is H26.21 listed in the Alphabetic Index?
These are the routes through the Alphabetic Index that lead to H26.21. They show the wording a clinician may have documented, which often differs from the Tabular description.
- Cataract › complicated › with › neovascularization (cortical) (immature) (incipient)
Code also
Two codes may be needed to describe the condition fully. Whether H26.21 is sequenced first depends on the reason for the encounter.
- , if applicable, associated condition, such as:
- chronic iridocyclitis (H20.1-)
Excludes1 — never code together — inherited from H26
The conditions below can never be reported together with H26.21 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 cataract (Q12.0)
Excludes2 — not included here — inherited from Chapter 7
The conditions below are not part of H26.21, but a patient may have both at the same time. When documentation supports it, H26.21 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)
