S02.110B — Type I occipital condyle fracture, unspecified side, initial encounter for open fracture

BillableUnspecifiedMCC

Is S02.110B billable?

Yes, but S02.110B will trip a Medicare edit. S02.110B is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, CMS lists S02.110B under Medicare Code Editor edit 20, “Unspecified code” — meaning a code specifying laterality (right, left or bilateral) exists in the same family. On an inpatient claim this triggers the edit, because CMS holds that there are very limited circumstances in which laterality cannot be documented.

What Medicare edits apply to S02.110B?

The Medicare Code Editor screens inpatient claims before they are grouped. These edits name S02.110B directly.

A code specifying laterality (right, left or bilateral) exists in the same family. CMS holds that there are very limited circumstances in which laterality cannot be documented.

Which MS-DRGs does S02.110B group to?

S02.110B sits in MDC 01 and helps define the logic of 3 MS-DRGs (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.

  • 082Traumatic Stupor and Coma >1 Hour with MCCmedical
  • 083Traumatic Stupor and Coma >1 Hour with CCmedical
  • 084Traumatic Stupor and Coma >1 Hour without CC/MCCmedical

As a secondary diagnosis, S02.110B is a major complication or comorbidity (MCC), which can move a stay into a higher-paying DRG. It also carries Hospital-Acquired Condition category 05.

How is S02.110B listed in the Alphabetic Index?

Report an additional code alongside S02.110B to fully describe the condition. S02.110B 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 S02.110B, but a patient may have both at the same time. When documentation supports it, S02.110B and the excluded code may both be reported.

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

Excludes2 — not included here — inherited from S00-S09

The conditions below are not part of S02.110B, but a patient may have both at the same time. When documentation supports it, S02.110B and the excluded code may both be reported.

  • burns and corrosions (T20-T32)
  • effects of foreign body in ear (T16)
  • effects of foreign body in larynx (T17.3)
  • effects of foreign body in mouth NOS (T18.0)
  • effects of foreign body in nose (T17.0-T17.1)
  • effects of foreign body in pharynx (T17.2)
  • effects of foreign body on external eye (T15.-)
  • frostbite (T33-T34)
  • insect bite or sting, venomous (T63.4)

Excludes2 — not included here — inherited from S02.1

The conditions below are not part of S02.110B, but a patient may have both at the same time. When documentation supports it, S02.110B and the excluded code may both be reported.

Code also — inherited from S00-S09

Two codes may be needed to describe the condition fully. Whether S02.110B is sequenced first depends on the reason for the encounter.
