Coding GuidelinesGuidance

The appropriate 7th character is to be added to each code from block Superficial injury of head (S00). Use the following options for the applicable episode of care:

  • A - initial encounter
  • D - subsequent encounter
  • S - sequela

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to S00: its own notes plus those printed at block S00-S09 and Chapter 19. A note printed at a category, block or chapter applies to every code under it.

  • focal cerebral contusion (S06.3-)
  • injury of eye and orbit (S05.-)
  • open wound of head (S01.-)

From Block S00-S09 Injuries to the head applies to 1,934 codes
  • burns and corrosions (T20-T32)
  • effects of foreign body in ear (T16)
  • effects of foreign body in larynx (T17.3)

From Chapter 19 (S00-T88) Injury, poisoning and certain other consequences of external causes applies to 41,187 codes

Use Additional Code

Add a second code, after this one, to fully describe the condition.

From Chapter 19 (S00-T88) Injury, poisoning and certain other consequences of external causes applies to 41,187 codes
  • code to identify any retained foreign body, if applicable (Z18.-)

Code Also

A second code may be needed to fully describe the condition; the note gives no sequencing direction.

From Block S00-S09 Injuries to the head applies to 1,934 codes
  • for any associated infection

Notes

General instructions on how these codes are used.

From Chapter 19 (S00-T88) Injury, poisoning and certain other consequences of external causes applies to 41,187 codes
  • Use secondary code(s) from Chapter 20, External causes of morbidity, to indicate cause of injury. Codes within the T section that include the external cause do not require an additional external cause code
  • The chapter uses the S-section for coding different types of injuries related to single body regions and the T-section to cover injuries to unspecified body regions as well as poisoning and certain other consequences of external causes.

7th Character

Every code in the category takes a 7th character from the listed values, with the placeholder X filling any empty positions before it.

  • The appropriate 7th character is to be added to each code from category S00
Values for category S00 Encounter: Initial, Subsequent, Sequela
  • Ainitial encounter
  • Dsubsequent encounter
  • Ssequela

Questions About S00Overview

What is the ICD-10 code for superficial injury of head?

S00 is the ICD-10-CM category for superficial injury of head, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is S00 (Superficial injury of head) a billable code?

No. This is a category header that groups the codes for superficial injury of head, and headers cannot be submitted on claims. Claims for superficial injury of head need a more specific code from this category, such as S00.00XA, S00.00XD, and S00.00XS.

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

Not as a rule. The Excludes1 note on S00 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).
