H59.0Disorders of the eye following cataract surgery

Non-billable headerICD-10-CM

H59.0 is a non-billable header ICD-10-CM code for disorders of the eye following cataract surgery. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 inherited from the categories above H59.0

These are not written on H59.0, but they bind it: a note on a category applies to every code beneath it. Billing H59.0 with anything listed here is a denial.

Written on H59 Intraoperative and postprocedural complications and disorders of eye and adnexa, not elsewhere classified

  • mechanical complication of intraocular lens (T85.2)
  • mechanical complication of other ocular prosthetic devices, implants and grafts (T85.3)
  • pseudophakia (Z96.1)
  • secondary cataracts (H26.4-)

Other codes that can never be billed with H59.0

These codes carry an Excludes1 note pointing at H59.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading H59.0 alone.

  • H43.0Vitreous prolapse
  • H35.35Cystoid macular degeneration

Risk adjustment

H59.0 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Code history

H59.0 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.

Questions about H59.0

Is H59.0 a billable ICD-10-CM code?
No. H59.0 is a non-billable header code. Code to a higher level of specificity using one of its child codes.
Where does H59.0 sit in the tabular list?
Diseases of the eye and adnexa (H00-H59), in the block Intraoperative and postprocedural complications and disorders of eye and adnexa, not elsewhere classified (H59).
What cannot be coded together with H59.0?
H59.0 carries Excludes1 notes, which means the conditions they list can never be coded together with it on the same encounter. Some are written on the categories above H59.0 (H59) and apply to it just the same.
