S01: Open wound of head
S01 is a non-billable header ICD-10-CM code for open wound of head. 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 S01
- A
- initial encounter
- D
- subsequent encounter
- S
- sequela
Excludes1: never code together
These conditions cannot occur together. Billing both on the same encounter is a denial.
- open skull fracture (S02.- with 7th character B)
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.
Code also
Both codes may be needed to describe the encounter fully. Sequencing depends on the reason for the visit.
