Is S02.3 a billable ICD-10-CM code?

No. S02.3 is a non-billable header code. Code to a higher level of specificity using one of its child codes.

Where does S02.3 sit in the tabular list?

Injury, poisoning and certain other consequences of external causes (S00-T88), in the block Injuries to the head (S00-S09).

What cannot be coded together with S02.3?

S02.3 carries an Excludes1 note, which means the conditions it lists can never be coded together with it on the same encounter.

S02.3 — Fracture of orbital floor

Non-billable headerICD-10-CM

S02.3 is a non-billable header ICD-10-CM code for fracture of orbital floor. It cannot be billed on its own: choose one of the more specific child codes below. This code also requires a 7th character before it is complete.

This code requires a 7th character

The appropriate 7th character is to be added to each code from category S02

A: initial encounter for closed fracture
B: initial encounter for open fracture
D: subsequent encounter for fracture with routine healing
G: subsequent encounter for fracture with delayed healing
K: subsequent encounter for fracture with nonunion
S: sequela

Excludes1 — never code together

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

orbit NOS (S02.85)

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.

lateral orbital wall (S02.84-)
medial orbital wall (S02.83-)
orbital roof (S02.1-)

Inclusion terms

Alternative wordings a physician may use in the chart for this same code.

Fracture of inferior orbital wall

Other codes that can never be billed with S02.3

These codes carry an Excludes1 note pointing at S02.3. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading S02.3 alone.

Risk adjustment

S02.3 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 S02.3

3 child codes. Green means billable.
