General instructions on how these codes are used.
- Use secondary code(s) from Chapter 20, External causes of morbidity, to indicate cause of injury. Codes within the T section that include the external cause do not require an additional external cause code
- The chapter uses the S-section for coding different types of injuries related to single body regions and the T-section to cover injuries to unspecified body regions as well as poisoning and certain other consequences of external causes.
7th Character
Every code in the category takes a 7th character from the listed values, with the placeholder X filling any empty positions before it.
- The appropriate 7th character is to be added to each code from category S31

Questions About S31.511SOverview
Is S31.511S a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report laceration without foreign body of unspecified external genital organs, male, sequela on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What does the 7th character S in S31.511S mean?
The final character S makes this a sequela code: it reports a lingering problem that remains after the laceration without foreign body of unspecified external genital organs, male itself has resolved, not the original event.
What MS-DRG does S31.511S group to?
When laceration without foreign body of unspecified external genital organs, male, sequela is the principal diagnosis on an inpatient stay, it groups to MS-DRG 729, 730, with relative weights from 0.6595 to 1.0553 depending on complications. Higher weights mean higher Medicare reimbursement.
Is S31.511S 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 without foreign body of unspecified external genital organs, male, sequela on inpatient claims. The code appears in the Injuries to the abdomen, lower back, lumbar spine, pelvis and external genitals (S30-S39) range of the CMS exempt list.
Can S31.511S be reported with S38.21?
Not as a rule. The Excludes1 note at S31.5, which applies to S31.511S, lists "traumatic amputation of external genital organs (S38.21, S38.22)". 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).
