Which MS-DRGs does K00.2 group to?

K00.2 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

Excludes1 — never code together

The conditions below can never be reported together with K00.2 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • abnormalities of teeth due to congenital syphilis (A50.5)
  • tuberculum Carabelli, which is regarded as a normal variation and should not be coded

How long has K00.2 existed?

K00.2 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.

Which codes are confused with K00.2?
