S27

Header — not billable

Injury of other and unspecified intrathoracic organs

The ICD-10 code for injury of other and unspecified intrathoracic organs is S27.

S27 is a non-billable header code. It groups related conditions but cannot be used on its own for reimbursement — select one of the 9 more specific codes below.

Clinical notes

Code also

Two codes may be needed to fully describe a condition, but unlike Code First/Use Additional Code, the sequencing order is not mandated by convention.

any associated open wound of thorax (S21.-)

Excludes2 (not included here)

An Excludes2 note means the excluded condition is not part of this one, but a patient can have both at the same time — in that case both codes may be reported together.

injury of cervical esophagus (S10-S19)
injury of trachea (cervical) (S10-S19)

7th character definitions

These definitions specify what each valid 7th-character value means for codes in this category.

7th character note

This category requires a 7th character to indicate additional clinical detail (e.g. encounter type: initial, subsequent, sequela). The code is incomplete without it.

The appropriate 7th character is to be added to each code from category S27

Documentation support

General coding-documentation guidance — not a substitute for payer-specific requirements or professional coding judgment.

•This is a non-billable header code. Documentation must support a more specific child code before this diagnosis can be reported on a claim.
•This code describes an unspecified presentation. If the medical record documents a more specific detail (e.g. laterality, type, or affected site), a more specific sibling code should be used instead — see Related codes below.
•This category requires a 7th character. Documentation should clearly indicate the episode of care (initial encounter, subsequent encounter, or sequela).
•As a general rule, code to the highest level of specificity supported by the documentation in the medical record.
