Code Description

ICD-10 N83.0 is a billable code used to indicate a diagnosis of follicular cyst of ovary.

Key Diagnostic Point:

Follicular cysts of the ovary are fluid-filled sacs that develop on the ovaries as a result of the normal menstrual cycle. They are typically benign and often resolve spontaneously without treatment. These cysts form when the follicle, which normally releases an egg during ovulation, fails to rupture and release the egg, leading to fluid accumulation. While most women will experience follicular cysts at some point in their lives, they are most common in women of reproductive age. Symptoms may include pelvic pain, irregular menstrual cycles, or pressure symptoms, but many women remain asymptomatic. In some cases, complications such as rupture or hemorrhage can occur, leading to acute abdominal pain and requiring medical intervention. Follicular cysts should be differentiated from other ovarian disorders, such as endometriomas, dermoid cysts, and polycystic ovary syndrome (PCOS), which may present with similar symptoms but require different management approaches. Regular monitoring through ultrasound may be indicated to ensure that the cysts are not growing or causing complications.

Gynecology

Documentation Requirements

Detailed patient history, imaging results, and treatment plans must be documented.

Common Clinical Scenarios

Routine gynecological exams revealing cysts, management of symptomatic cysts, and follow-up on cyst resolution.

Billing Considerations

Radiology

Documentation Requirements

Clear imaging reports indicating the size, appearance, and characteristics of the cyst.

Common Clinical Scenarios

Ultrasound evaluations of pelvic pain or incidental findings during imaging.

Billing Considerations

Radiologists should provide detailed descriptions to aid in accurate coding.
