Does anyone know what cpt code to use for drainage of infected urethral diverticulm? I was leaning towards 10160 but not sure if accurate.

From PT’s chart –
"URETHRA: 5cm x 2cm large urethral diverticulum present. When mass was palpated, about 20ml of purulent fluid
was expressed through urethra. After obtaining permission from patient, local anesthetic was applied to the
anterior vagina and additional 5ml of purulent fluid was obtained percutaneously via needle decompression.
Resultant diverticular sac felt to be originating from midurethra with potential loculations still present
but not able to be successfully drained at present time. Bleeding noted from anterior vaginal wall puncture
sites which resolved with holding pressure."

"Today, we decompressed majority of diverticulum transurethrally and percutaneously. A straight catheterized urine culture was sent and needle aspirated fluid also sent for culture."

Thanks in advance for any help someone may offer! This is not a procedure I’ve ever coded for before!
