Which MS-DRGs does S11.20XA group to?
S11.20XA 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, S11.20XA is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.

Excludes1 — never code together — inherited from S11.2
The conditions below can never be reported together with S11.20XA on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- open wound of esophagus NOS (S27.8-)
Use additional code — inherited from Chapter 19
Report an additional code alongside S11.20XA to fully describe the condition. S11.20XA 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 S11.20XA, but a patient may have both at the same time. When documentation supports it, S11.20XA and the excluded code may both be reported.
Excludes2 — not included here — inherited from S10-S19

Excludes2 — not included here — inherited from S11

- open fracture of vertebra (S12.- with 7th character B)
Code also — inherited from S11
Two codes may be needed to describe the condition fully. Whether S11.20XA is sequenced first depends on the reason for the encounter.
How long has S11.20XA existed?
S11.20XA has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
