Diseases of the skin, subcu comp pregnancy, first trimester

This code signifies a skin or subcutaneous tissue disorder that arises or is exacerbated during the first trimester of pregnancy. It covers conditions such as dermatoses, infections, or other integumentary system diseases that complicate the pregnancy.

Apply this code when a pregnant patient in her first trimester presents with a skin condition that is either new onset or significantly worsened due to the pregnancy. Documentation should clearly link the skin condition to the pregnancy and specify the first trimester.

• Always sequence the obstetric code (O-code) as the primary diagnosis, followed by the specific code for the skin condition.
• Ensure the medical record explicitly states the trimester of pregnancy.
• Do not use this code for skin conditions unrelated to pregnancy or those that existed prior to pregnancy without exacerbation.
