Diseases of the skin, subcu comp pregnancy, second trimester

This code signifies a skin or subcutaneous tissue disorder that is adversely affecting a pregnant patient during her second trimester. This includes conditions such as dermatitis, psoriasis, infections (e.g., cellulitis, impetigo), or other integumentary system diseases that are either exacerbated by pregnancy or directly impact the pregnancy's course.

Apply this code when a pregnant patient in her second trimester presents with a pre-existing or new dermatological condition that is documented as complicating the pregnancy. Documentation should clearly link the skin condition to the pregnancy, indicating it requires management due to its impact on the maternal or fetal well-being.

• Always sequence this code as a secondary diagnosis, following the primary code for the specific skin condition.
• Ensure the medical record explicitly states the trimester of pregnancy to justify the "second trimester" specificity.
• Do not use this code if the skin condition is merely co-occurring with pregnancy but not documented as complicating it.
