Questions About S61.122DOverview

Is S61.122D a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report laceration with foreign body of left thumb with damage to nail, subsequent encounter on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What does the 7th character D in S61.122D mean?

The final character D marks a subsequent encounter: use it for routine care while the laceration with foreign body of left thumb with damage to nail is healing, after active treatment has ended.

What MS-DRG does S61.122D group to?

When laceration with foreign body of left thumb with damage to nail, subsequent encounter is the principal diagnosis on an inpatient stay, it groups to MS-DRG 950, 949, with relative weights from 0.7661 to 1.1231 depending on complications. Higher weights mean higher Medicare reimbursement.

Is S61.122D exempt from POA reporting?

Yes. CMS lists this code among those exempt from present on admission reporting, so hospitals do not assign a POA indicator for laceration with foreign body of left thumb with damage to nail, subsequent encounter on inpatient claims. The code appears in the Injuries to the wrist, hand and fingers (S60-S69) range of the CMS exempt list.

Can S61.122D be reported with a code from S62?

Not as a rule. The Excludes1 note at S61, which applies to S61.122D, lists "open fracture of wrist, hand and finger (S62.- with 7th character B)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
