  • Trisomy › whole chromosome › mitotic nondisjunction (syndrome)

  • Trisomy › chromosome specified NEC › whole › mitotic nondisjunction (syndrome)
  • Trisomy › chromosome specified NEC › whole › mosaicism (syndrome)

Excludes1 — never code together — inherited from Q92

The conditions below can never be reported together with Q92.1 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • trisomies of chromosomes 13, 18, 21 (Q90-Q91)

Excludes2 — not included here — inherited from Chapter 17

The conditions below are not part of Q92.1, but a patient may have both at the same time. When documentation supports it, Q92.1 and the excluded code may both be reported.

  • inborn errors of metabolism (E70-E88)

Excludes2 — not included here — inherited from Q90-Q99

The conditions below are not part of Q92.1, but a patient may have both at the same time. When documentation supports it, Q92.1 and the excluded code may both be reported.

  • mitochondrial metabolic disorders (E88.4-)

How long has Q92.1 existed?

Q92.1 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.
