  • Lacerationthorax, thoracicbackwithpenetration into thoracic cavity

Excludes1 — never code together — inherited from S21

The conditions below can never be reported together with S21.411S on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • traumatic amputation (partial) of thorax (S28.1)

Use additional code — inherited from Chapter 19

Report an additional code alongside S21.411S to fully describe the condition. S21.411S is sequenced first.

  • code to identify any retained foreign body, if applicable (Z18.-)

Excludes2 — not included here — inherited from Chapter 19

The conditions below are not part of S21.411S, but a patient may have both at the same time. When documentation supports it, S21.411S and the excluded code may both be reported.

  • birth trauma (P10-P15)
  • obstetric trauma (O70-O71)

Excludes2 — not included here — inherited from S20-S29

The conditions below are not part of S21.411S, but a patient may have both at the same time. When documentation supports it, S21.411S and the excluded code may both be reported.

  • burns and corrosions (T20-T32)
  • effects of foreign body in bronchus (T17.5)
  • effects of foreign body in esophagus (T18.1)
  • effects of foreign body in lung (T17.8)
  • effects of foreign body in trachea (T17.4)
  • frostbite (T33-T34)
  • injuries of axilla
  • injuries of clavicle
  • injuries of scapular region
  • injuries of shoulder
  • insect bite or sting, venomous (T63.4)

Code also — inherited from S21

Two codes may be needed to describe the condition fully. Whether S21.411S is sequenced first depends on the reason for the encounter.

  • any associated injury, such as:
  • injury of heart (S26.-)
  • injury of intrathoracic organs (S27.-)
  • rib fracture (S22.3-, S22.4-)
  • spinal cord injury (S24.0-, S24.1-)
  • traumatic hemopneumothorax (S27.3)
  • traumatic hemothorax (S27.1)
