Eye Injuries

The structure of your face helps protect your eyes from injury. Still, injuries can damage your eye, sometimes severely enough that you could lose your vision. Most eye injuries are preventable. If you play sports or work in certain jobs, you may need protection.

Questions About S00.269DOverview

Is S00.269D a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report insect bite (nonvenomous) of unspecified eyelid and periocular area, subsequent encounter on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What does the 7th character D in S00.269D mean?

The final character D marks a subsequent encounter: use it for routine care while the insect bite (nonvenomous) of unspecified eyelid and periocular area is healing, after active treatment has ended.

What MS-DRG does S00.269D group to?

When insect bite (nonvenomous) of unspecified eyelid and periocular area, subsequent encounter is the principal diagnosis on an inpatient stay, it groups to MS-DRG 950, 949, with relative weights from 0.7661 to 1.1231 depending on complications. Higher weights mean higher Medicare reimbursement.

Is S00.269D exempt from POA reporting?

Yes. CMS lists this code among those exempt from present on admission reporting, so hospitals do not assign a POA indicator for insect bite (nonvenomous) of unspecified eyelid and periocular area, subsequent encounter on inpatient claims. The code appears in the Injuries to the head (S00-S09) range of the CMS exempt list.

Can S00.269D be reported with a code from S06.2?

Not as a rule. The Excludes1 note at S00, which applies to S00.269D, lists "diffuse cerebral contusion (S06.2-)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
