Diseases of the skin, subcu comp pregnancy, unsp trimester

This code signifies any skin or subcutaneous tissue disorder that arises during or is exacerbated by pregnancy, without specifying the trimester. It encompasses a broad range of dermatological conditions, such as eczema, psoriasis, pruritic urticarial papules and plaques of pregnancy (PUPPP), or infections, when they complicate the gravid state. The condition is considered to have a direct impact on the pregnancy or the pregnant individual's health.

Apply this code when a pregnant patient presents with a skin or subcutaneous tissue disease, and the medical record clearly indicates that the condition is complicating the pregnancy. This code is appropriate when the specific trimester is not documented or is unknown. Documentation should explicitly link the dermatological issue to the pregnancy.

• Always strive for a more specific code if the trimester is documented (e.g., O99.711, O99.712, O99.713).
• Code the specific skin condition first, followed by this complication code, to fully describe the patient's diagnosis.
• Ensure documentation supports the "complicating pregnancy" aspect; a pre-existing skin condition that is merely present during pregnancy without exacerbation or impact would not typically warrant this code.
