Is H59 a billable ICD-10-CM code?

No. H59 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?

H59 carries an Excludes1 note, which means the conditions it lists can never be coded together with it on the same encounter.

H59

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

Non-billable headerICD-10-CM

H59 is a non-billable header ICD-10-CM code for intraoperative and postprocedural complications and disorders of eye and adnexa, not elsewhere classified. 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.

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

These codes carry an Excludes1 note pointing at H59. 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 alone.

Z98.83Filtering (vitreous) bleb after glaucoma surgery status
H31.01Macula scars of posterior pole (postinflammatory) (post-traumatic)
H33.3Retinal breaks without detachment
H35.35Cystoid macular degeneration
H43.0Vitreous prolapse
H44.0Purulent endophthalmitis
H44.1Other endophthalmitis
H59.1Intraoperative hemorrhage and hematoma of eye and adnexa complicating a procedure

Risk adjustment

H59 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 to one of these instead H59

6 child codes. Green means billable.
