Primary dysmenorrhea

This code represents painful menstruation that is not caused by an underlying pelvic pathology. It is characterized by cramping pain in the lower abdomen, often radiating to the back or thighs, typically occurring just before or during the menstrual period. The pain can range from mild to severe and may be accompanied by other symptoms like nausea, vomiting, diarrhea, fatigue, or headache.

Use this code when documentation clearly indicates dysmenorrhea without an identified secondary cause such as endometriosis, fibroids, or pelvic inflammatory disease. This diagnosis is often made after a thorough history and physical examination, and potentially after ruling out other conditions. It is appropriate for initial presentations and follow-up visits for primary dysmenorrhea management.

• Ensure documentation explicitly states "primary" dysmenorrhea or indicates no secondary cause has been identified.
• Do not use this code if an underlying gynecological condition causing the pain is diagnosed; instead, code the specific underlying condition.
• Consider co-reporting with codes for associated symptoms (e.g., R11.2 for nausea and vomiting) if they are significant and documented.
