Endometriosis of bladder, unspecified depth

This code describes the presence of endometrial tissue within the bladder wall, where the specific depth of invasion is not documented. This is a form of extrapelvic endometriosis, causing symptoms such as dysuria, hematuria, and suprapubic pain, often cyclical with menstruation.

Use this code when documentation confirms endometriosis affecting the bladder, but the provider has not specified whether it's superficial, deep, or full-thickness involvement. This code is appropriate when the diagnostic workup (e.g., cystoscopy with biopsy, imaging) identifies bladder involvement without further detail on depth.

• Do not use this code if the depth of bladder involvement (e.g., superficial, deep) is clearly documented; instead, select a more specific N80.A- subcategory.
• Always review the operative report or pathology report for precise anatomical location and depth of endometriosis.
• Consider sequencing this code after codes for other pelvic endometriosis sites if multiple locations are present.
