Using unspecified codes (e.g., N91.8) when more specific diagnoses like oligomenorrhea (N91.5) or secondary amenorrhea (N91.2) are clinically documented, impacting reimbursement and data accuracy.
Insufficient documentation of cycle frequency, duration, and associated symptoms (e.g., heavy menstrual bleeding, pelvic pain) to support irregular period diagnosis, leading to audit denials.
Incorrectly coding irregular periods as menorrhagia (N92.0) without documentation of abnormally heavy or prolonged bleeding, causing coding errors and compliance issues.
Patient presents with a chief complaint of irregular periods, medically termed as irregular menstruation or oligomenorrhea. The patient reports experiencing variations in menstrual cycle length and frequency, including infrequent periods, prolonged cycles, and unpredictable bleeding patterns. Menstrual history includes menarche at age [Patient Age at Menarche], with an average cycle length of [Patient Average Cycle Length] days prior to the onset of irregularity. The patient describes the flow as [Patient Description of Flow: e.g., light, normal, heavy] and denies experiencing significant dysmenorrhea or intermenstrual bleeding. Current symptoms include [List Patient Symptoms: e.g., mood swings, acne, weight changes, hirsutism, fatigue]. Differential diagnoses considered include polycystic ovary syndrome (PCOS), hormonal imbalances, thyroid dysfunction, stress, excessive exercise, eating disorders, perimenopause, uterine fibroids, and other potential underlying medical conditions. A detailed review of systems was conducted and physical examination performed, noting [Specific Findings from Physical Examination]. Laboratory tests ordered include a complete blood count (CBC), comprehensive metabolic panel (CMP), thyroid panel (TSH, free T4), prolactin levels, and potentially follicle-stimulating hormone (FSH) and luteinizing hormone (LH) levels to evaluate ovarian function. Pelvic ultrasound may be considered to assess uterine and ovarian morphology. Preliminary assessment suggests [Preliminary Assessment: e.g., possible PCOS, hormonal imbalance]. The patient was counseled on the potential causes of irregular menses, diagnostic procedures, and possible treatment options including hormonal therapy, lifestyle modifications, and management of underlying conditions. Follow-up appointment scheduled for [Date of Follow-Up] to review laboratory results and discuss further management based on findings. ICD-10 code N92.6 (Other specified abnormalities of menstruation) is considered pending further diagnostic evaluation.
