About coding Suburethral cyst
The ICD-10-CM code for Suburethral cyst is N36.8 (Other specified disorders of urethra).
Within N36, choose N36.8 (Other specified disorders of urethra) only when documentation doesn't support a more specific option: urethral fistula (N36.0), urethral diverticulum (N36.1), urethral caruncle (N36.2), urethral functional and muscular disorders (N36.4), urethral false passage (N36.5) and urethral disorder, unspecified (N36.9).
Don't report N36.8 together with the conditions in its Excludes1 note: congenital urethrocele (Q64.7) and female urethrocele (N81.0).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
Don't confuse with (Excludes1 for N36.8)
