Is Q92.5 a billable ICD-10-CM code?

Yes. Q92.5 is a billable, specific ICD-10-CM code and is valid for submission on a claim.

Where does Q92.5 sit in the tabular list?

Congenital malformations, deformations and chromosomal abnormalities (Q00-QA0), in the block Chromosomal abnormalities, not elsewhere classified (Q90-Q99).

What cannot be coded together with Q92.5?

Q92.5 carries Excludes1 notes, which means the conditions they list can never be coded together with it on the same encounter. Some are written on the categories above Q92.5 (Q92) and apply to it just the same.

Q92.5

Q92.5 — Duplications with other complex rearrangements

Billable / specific codeICD-10-CMPOA exempt

Q92.5 is a billable, specific ICD-10-CM code for duplications with other complex rearrangements. It is valid for submission on a claim.

Code also

Both codes may be needed to describe the encounter fully. Sequencing depends on the reason for the visit.

any associated deletions due to unbalanced translocations, inversions and insertions (Q93.7)

Inclusion terms

Alternative wordings a physician may use in the chart for this same code.

Partial trisomy due to unbalanced translocations

Excludes1 inherited from the categories above Q92.5

These are not written on Q92.5, but they bind it: a note on a category applies to every code beneath it. Billing Q92.5 with anything listed here is a denial.

Written on Q92 — Other trisomies and partial trisomies of the autosomes, not elsewhere classified

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

Other codes that can never be billed with Q92.5

These codes carry an Excludes1 note pointing at Q92.5. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading Q92.5 alone.

Q92.2Partial trisomy

Risk adjustment

Q92.5 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

How Q92.5 is indexed

Coders do not find codes by browsing the tabular list — they look them up in the alphabetic index, under the word the physician wrote. These are the index entries that lead here, so you can see which chart wordings map to Q92.5.

Accessory›chromosome›with complex rearrangements NEC
Duplication, duplex›chromosome NEC›with complex rearrangements NEC

Code history

Q92.5 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
