Spotting complicating pregnancy, first trimester

This code signifies the occurrence of vaginal bleeding or spotting during the first trimester of pregnancy (up to 13 weeks and 6 days gestation), which is considered a complication. It indicates that the bleeding is not a normal physiological event and warrants clinical attention.

Apply this code when a pregnant patient in her first trimester presents with any amount of vaginal bleeding or spotting. Documentation should clearly state "spotting" or "bleeding" and specify the gestational age or trimester. This code is appropriate when the bleeding is not attributed to a threatened abortion, ectopic pregnancy, or other specific causes.

• Always confirm the trimester of pregnancy from the medical record.
• Differentiate from codes for threatened abortion (O20.0) or other specific causes of bleeding in early pregnancy.
• This code is often a secondary diagnosis, with the primary diagnosis reflecting the reason for the encounter or the underlying cause if identified.
