H44.6

H44.6 — Retained (old) intraocular foreign body, magnetic

Non-billable headerICD-10-CM

H44.6 is a non-billable header ICD-10-CM code for retained (old) intraocular foreign body, magnetic. 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.

current intraocular foreign body (S05.-)

Excludes2 — not included here, but may coexist

The excluded condition is not part of this code, but a patient can have both. You may code both.

retained foreign body in eyelid (H02.81-)
retained (old) foreign body following penetrating wound of orbit (H05.5-)
retained (old) intraocular foreign body, nonmagnetic (H44.7-)

Use additional code

Add a secondary code to capture the detail described below.

code to identify magnetic foreign body (Z18.11)

Other codes that can never be billed with H44.6

These codes carry an Excludes1 note pointing at H44.6. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading H44.6 alone.

Risk adjustment

H44.6 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 H44.6

7 child codes. Green means billable.

Related codes at this level

Codes that share H44. If H44.6 is not quite right, the correct code is usually one of these.
