Which MS-DRGs does S02.31XB group to?
S02.31XB sits in MDC Pre 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.
- 011Tracheostomy for Face, Mouth and Neck Diagnoses or Laryngectomy with MCCsurgical
- 012Tracheostomy for Face, Mouth and Neck Diagnoses or Laryngectomy with CCsurgical
- 013Tracheostomy for Face, Mouth and Neck Diagnoses or Laryngectomy without CC/MCCsurgical
As a secondary diagnosis, S02.31XB is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG. It also carries Hospital-Acquired Condition category 05.

Excludes1 — never code together — inherited from S02.3
The conditions below can never be reported together with S02.31XB on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- orbit NOS (S02.85)
Use additional code — inherited from Chapter 19
Report an additional code alongside S02.31XB to fully describe the condition. S02.31XB 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 S02.31XB, but a patient may have both at the same time. When documentation supports it, S02.31XB and the excluded code may both be reported.
Excludes2 — not included here — inherited from S00-S09
The conditions below are not part of S02.31XB, but a patient may have both at the same time. When documentation supports it, S02.31XB 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 S02.3
The conditions below are not part of S02.31XB, but a patient may have both at the same time. When documentation supports it, S02.31XB 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 S02.31XB 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 S02.31XB is sequenced first depends on the reason for the encounter.
- any associated intracranial injury (S06.-)
How long has S02.31XB existed?
S02.31XB first appears in FY2018 (FY2017 is not available, so it may have appeared then).
Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
