BillablePlacenta increta, first trimester

What This Code Means
The placenta has invaded into the uterine muscle layer (placenta increta) during the first trimester of pregnancy, creating a more serious attachment problem than simple accreta.
Coding Tips
- •Document the trimester clearly in the medical record to ensure accurate code selection
- •Placenta increta is more severe than accreta and requires careful delivery planning; ensure documentation reflects the depth of invasion if known
