Other specified predominantly sexually transmitted diseases

This code represents sexually transmitted infections that are not explicitly classified elsewhere in ICD-10-CM. It encompasses a range of less common or atypical STIs that are predominantly transmitted through sexual contact. These conditions may present with various symptoms affecting the genitourinary tract, skin, or other organ systems.

Use this code when documentation clearly indicates a sexually transmitted disease that does not have a more specific ICD-10-CM code. This includes conditions like molluscum contagiosum when sexually acquired, or other rare or emerging STIs. Physician documentation must explicitly state the diagnosis and confirm its predominant sexual transmission.

• Ensure the documentation specifies "sexually transmitted" for conditions that can have other modes of transmission.
• Always search for a more specific code first before resorting to this "other specified" category.
• Do not use this code for unspecified STIs; refer to codes like A64 for unspecified sexually transmitted disease.
