ICD-10/S06.A1XD

S06.A1XD ICD-10-CM Code: Traumatic brain compression with herniation, subsequent encounter

Billing Status: YES. This is a valid, specific, and billable ICD-10-CM reference.

Inpatient Payment Groups (MS-DRG)

MS-DRGs this diagnosis helps define, as principal or secondary, per the CMS ICD-10-CM/PCS MS-DRG Definitions Manual v43.0, Appendix B.

A diagnosis appearing in a group's logic does not by itself determine the DRG assigned to a stay; the grouper uses the full claim.

Official Registry Overview & Definition

Traumatic brain compression with herniation, subsequent encounter is a billable ICD-10-CM diagnosis code (S06.A1D).

Official Tabular Instructional Notes

Inclusion Terms

Alternative terms the tabular list files under this code.

  • Traumatic brain herniation
  • Traumatic brainstem compression with herniation
  • Traumatic cerebellar compression with herniation
  • Traumatic cerebral compression with herniation

Excludes1 — Not Coded Here

Conditions generally not reported together with this code (Excludes1) -- an error unless the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).

Excludes2 — Not Included Here

Conditions not covered by this code, but which may be reported alongside it when both are present.

Code First

Underlying conditions that must be sequenced before this code.

  • the underlying traumatic brain injury, such as:
  • diffuse traumatic brain injury (S06.2-)
  • focal traumatic brain injury (S06.3-)
  • traumatic subdural hemorrhage (S06.5-)
  • traumatic subarachnoid hemorrhage (S06.6-)

Code Also

Additional codes that may be required to fully describe the encounter.

  • any associated:
  • open wound of head (S01.-)
  • skull fracture (S02.-)
  • for any associated infection

Use Additional Code

Supplementary codes the tabular list directs you to add.

  • Use additional code, if applicable, to identify mild neurocognitive disorders due to known physiological condition (F06.7-)

Verify Before Coding

  • Billable — reportable as written.
  • Principal-diagnosis restriction. The Medicare Code Editor lists this code as unacceptable as a principal diagnosis: it describes a circumstance influencing health status rather than a current illness or injury being treated. It is valid as a secondary diagnosis.

From the code registry, the Medicare Code Editor, and the MS-DRG Definitions Manual. Check it against a full claim.
