W27.3XXS — Contact with needle (sewing), sequela
W27.3XXS is a billable, specific ICD-10-CM code for contact with needle (sewing), sequela. It is valid for submission on a claim.
7th character "S" — sequela
The appropriate 7th character is to be added to each code from category W27
- A
- initial encounter
- D
- subsequent encounter
- S
- sequela
Excludes1 — never code together
These conditions cannot occur together. Billing both on the same encounter is a denial.
- contact with hypodermic needle (W46.-)
Excludes1 inherited from the categories above W27.3XXS
These are not written on W27.3XXS, but they bind it: a note on a category applies to every code beneath it. Billing W27.3XXS with anything listed here is a denial.
Other codes that can never be billed with W27.3XXS
These codes carry an Excludes1 note pointing at W27.3XXS. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading W27.3XXS alone.
Risk adjustment
W27.3XXS 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.
Code history
W27.3XXS has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
