2025 ICD-10-CM code Q50.4

Embryonic cyst of fallopian tube.

This code should not be used on maternal records unless the condition persists postpartum. For prenatal diagnoses, the code is applicable to fetal records.

Medical necessity for intervention (e.g., surgical removal) is determined based on factors such as symptoms, size and location of the cyst, impact on fertility, and potential for complications like torsion or rupture.

Diagnosis and management of this condition falls under the purview of gynecologists, obstetricians, and in some cases, pediatricians specializing in neonatal care.Clinical responsibility includes diagnostic evaluation, potential surgical intervention, and ongoing monitoring as needed.

In simple words: This condition involves a cyst (a fluid-filled sac) in the fallopian tube that is present from birth.

This code represents a congenital condition characterized by the presence of a cyst in the fallopian tube, resulting from embryonic development.It is classified under congenital malformations of the genital organs.

Example 1: A newborn female is found to have an asymptomatic embryonic cyst of the fallopian tube during a routine postnatal ultrasound.The cyst is small and requires no immediate intervention, but monitoring is recommended.Q50.4 is coded., A 25-year-old woman experiencing infertility undergoes diagnostic laparoscopy, revealing an embryonic cyst of the fallopian tube. The cyst is surgically removed. Q50.4 is coded along with any applicable procedural codes., A female fetus is diagnosed with an embryonic cyst of the fallopian tube during a prenatal ultrasound. Q50.4 is coded on fetal records. Note: While this chapter (Q00-Q99) is generally not used for maternal records, the code can be used on the fetal record.The maternal record should reflect any associated conditions or complications related to the fetal diagnosis.

Documentation should include imaging reports (ultrasound, MRI, etc.), operative reports if surgery is performed, and any relevant clinical findings related to the cyst. The size and location of the cyst should be specified.

** It's important to distinguish Q50.4 (embryonic cyst of fallopian tube) from other types of fallopian tube cysts that may arise later in life, such as parovarian cysts or hydrosalpinges.These other cyst types have their own specific ICD-10-CM codes.
