S11 — Open wound of neck

Non-billable headerICD-10-CM

S11 is a non-billable header ICD-10-CM code for open wound of neck. 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 S11

A: initial encounter
D: subsequent encounter
S: sequela

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.

open fracture of vertebra (S12.- with 7th character B)

Code also

Both codes may be needed to describe the encounter fully. Sequencing depends on the reason for the visit.

any associated:
spinal cord injury (S14.0, S14.1-)
wound infection

Other codes that can never be billed with S11

These codes carry an Excludes1 note pointing at S11. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading S11 alone.

S10.17Other superficial bite of throat
S10.17XAOther superficial bite of throat, initial encounter
S10.17XDOther superficial bite of throat, subsequent encounter
S10.17XSOther superficial bite of throat, sequela
S10.87Other superficial bite of other specified part of neck
S10.87XAOther superficial bite of other specified part of neck, initial encounter
S10.87XDOther superficial bite of other specified part of neck, subsequent encounter
S10.87XSOther superficial bite of other specified part of neck, sequela

Risk adjustment

S11 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 S11

5 child codes. Green means billable.
