Is K62.82 (Other specified diseases of anus and rectum) a billable code?

When dysplasia of anus is the principal diagnosis on an inpatient stay, it groups to MS-DRG 394, 395, 393, with relative weights from 0.6379 to 1.5877 depending on complications. Higher weights mean higher Medicare reimbursement.

Not as a rule. The Excludes1 note on K62.82 lists "abnormal results from anal cytologic examination without histologic confirmation (R85.61-)". 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).

Under the General Equivalence Mappings, dysplasia of anus converts to ICD-9-CM 569.44 (dysplasia of anus). The mapping is a direct match.
