S02.600K — Fracture of unspecified part of body of mandible, unspecified side, subsequent encounter for fracture with nonunion

BillableUnspecifiedCC

Is S02.600K billable?

Yes, but S02.600K will trip a Medicare edit. S02.600K is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, CMS lists S02.600K 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 S02.600K?

The Medicare Code Editor screens inpatient claims before they are grouped. These edits name S02.600K directly.

Unspecified — a laterality-specific code exists — MCE edit 20

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 S02.600K group to?

S02.600K sits in MDC 08 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.

  • 564Other Musculoskeletal System and Connective Tissue Diagnoses with MCCmedical
  • 565Other Musculoskeletal System and Connective Tissue Diagnoses with CCmedical
  • 566Other Musculoskeletal System and Connective Tissue Diagnoses without CC/MCCmedical

As a secondary diagnosis, S02.600K is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.

How is S02.600K listed in the Alphabetic Index?

The Alphabetic Index lists these routes under S02.600, the nearest indexed parent of S02.600K. Use them to find the family, then select the specific code.

  • Fracture, traumatic › mandible › body, unspecified (abduction) (adduction) (separation)

Use additional code — inherited from Chapter 19

Report an additional code alongside S02.600K to fully describe the condition. S02.600K 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 S02.600K, but a patient may have both at the same time. When documentation supports it, S02.600K 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 S02.600K, but a patient may have both at the same time. When documentation supports it, S02.600K 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)

Code also — inherited from S00-S09

Two codes may be needed to describe the condition fully. Whether S02.600K is sequenced first depends on the reason for the encounter.

  • for any associated infection

Code also — inherited from S02

Two codes may be needed to describe the condition fully. Whether S02.600K is sequenced first depends on the reason for the encounter.

  • any associated intracranial injury (S06.-)

How long has S02.600K existed?

S02.600K has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
