Testing of Premature Rupture of Membranes via Indigo Carmine Injection
A patient presented at 32 weeks and 1 day for a routine obstetric appointment and was admitted due to suspected premature rupture of membranes. After several days of no leaking and with normal amniotic fluid on ultrasound, a decision was made to assess whether the membranes were intact. Under ultrasound guidance, a 22-gauge spinal needle was placed inside the amniotic cavity; 2 mL of amniotic fluid were removed. At this point, 2 mL of indigo carmine were injected into the amniotic cavity without difficulty. A tampon was placed in the vagina to assess whether or not the membranes were ruptured. The results of the amnio indigo carmine test were negative for premature rupture of membranes. What is the correct ICD-10-PCS code assignment for an injection of indigo carmine to determine preterm premature rupture of membranes (PROM)? ...
