Is H59.1 a billable ICD-10-CM code?

No. H59.1 is a non-billable header code. Code to a higher level of specificity using one of its child codes.

What cannot be coded together with H59.1?

H59.1 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 H59.1 (H59) and apply to it just the same.

H59.1

H59.1 — Intraoperative hemorrhage and hematoma of eye and adnexa complicating a procedure

Non-billable headerICD-10-CM

H59.1 is a non-billable header ICD-10-CM code for intraoperative hemorrhage and hematoma of eye and adnexa complicating a procedure. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

intraoperative hemorrhage and hematoma of eye and adnexa due to accidental puncture or laceration during a procedure (H59.2-)

Excludes1 inherited from the categories above H59.1

These are not written on H59.1, but they bind it: a note on a category applies to every code beneath it. Billing H59.1 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-)

Risk adjustment

H59.1 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

H59.1 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.

Code to one of these instead H59.1

2 child codes. Green means billable.
