Which MS-DRGs does Q32.1 group to?
Q32.1 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, Q32.1 is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.
How is Q32.1 listed in the Alphabetic Index?
These are the routes through the Alphabetic Index that lead to Q32.1. They show the wording a clinician may have documented, which often differs from the Tabular description.
- Absence › trachea, congenital (of) (organ or part) (complete or partial)
- Agenesis › trachea
- Anomaly, anomalous › trachea (congenital) (unspecified type)
- Atresia, atretic › trachea
- Bifurcation › trachea (congenital)
- Deformity › trachea
- Dilatation › trachea, congenital
- Displacement, displaced › trachea
- Distortion › trachea (s) (congenital)
- Fistula › trachea, congenital (cutaneous)
- Malformation › trachea (congenital)
- Separation › tracheal ring, incomplete, congenital
Inclusion terms
Alternative wording in documentation that is classified to Q32.1.
- Atresia of trachea
- Congenital anomaly of tracheal cartilage
- Congenital dilatation of trachea
- Congenital malformation of trachea
- Congenital stenosis of trachea
- Congenital tracheocele
Excludes1 — never code together — inherited from Q32
The conditions below can never be reported together with Q32.1 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- congenital bronchiectasis (Q33.4)
Excludes2 — not included here — inherited from Chapter 17
The conditions below are not part of Q32.1, but a patient may have both at the same time. When documentation supports it, Q32.1 and the excluded code may both be reported.
- inborn errors of metabolism (E70-E88)
How long has Q32.1 existed?
Q32.1 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.
