Which MS-DRGs does Q31.5 group to?
Q31.5 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, Q31.5 is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.
How is Q31.5 listed in the Alphabetic Index?
These are the routes through the Alphabetic Index that lead to Q31.5. They show the wording a clinician may have documented, which often differs from the Tabular description.
- Laryngomalacia (congenital)
Excludes1 — never code together — inherited from Q31
The conditions below can never be reported together with Q31.5 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 laryngeal stridor NOS (P28.89)
Excludes2 — not included here — inherited from Chapter 17
The conditions below are not part of Q31.5, but a patient may have both at the same time. When documentation supports it, Q31.5 and the excluded code may both be reported.
- inborn errors of metabolism (E70-E88)
How long has Q31.5 existed?
