Q97.8 — Other specified sex chromosome abnormalities, female phenotype
Is Q97.8 billable?
Yes, but Q97.8 is an unspecified code. Q97.8 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, Q97.8 is an unspecified or catch-all code. Payers apply additional scrutiny to unspecified codes and many deny them when the medical record supports a more specific option, so check the documentation before selecting Q97.8 — the more specific alternatives are listed below.

Excludes1 — never code together — inherited from Q97
The conditions below can never be reported together with Q97.8 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- Turner's syndrome (Q96.-)
Excludes2 — not included here — inherited from Chapter 17
The conditions below are not part of Q97.8, but a patient may have both at the same time. When documentation supports it, Q97.8 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 Q97.8, but a patient may have both at the same time. When documentation supports it, Q97.8 and the excluded code may both be reported.
- mitochondrial metabolic disorders (E88.4-)
How long has Q97.8 existed?
Q97.8 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.
