Questions About N35.116Overview

Is N35.116 a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report postinfective urethral stricture, not elsewhere classified, male, overlapping sites on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What MS-DRG does N35.116 group to?

When postinfective urethral stricture, not elsewhere classified, male, overlapping sites is the principal diagnosis on an inpatient stay, it groups to MS-DRG 697 (urethral Stricture), which carries a relative weight of 0.9656. Higher weights mean higher Medicare reimbursement.

Can N35.116 be reported with a code from B65?

Not as a rule. The Excludes1 note at N35.1, which applies to N35.116, lists "urethral stricture associated with schistosomiasis (B65.-, N29)". 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).
