Coding A59.9 (Trichomoniasis, unspecified) when clinical documentation supports a more specific site (e.g., urogenital) leads to inaccurate data and potential underpayment.
Overlooking other STIs present with Trichomoniasis (e.g., Chlamydia, Gonorrhea) impacts quality metrics and reimbursement for combination therapies.
Incorrectly using a screening code (Z11.3) when Trichomoniasis is symptomatic creates coding errors and affects public health surveillance data.
Patient presents with complaints consistent with trichomoniasis. Symptoms include vaginal discharge described as frothy, yellow-green, and malodorous. Patient also reports vulvovaginal itching, dyspareunia, and mild dysuria. On examination, erythema and edema of the vulva and vagina are noted. A wet mount preparation revealed motile trichomonads, confirming the diagnosis of trichomoniasis vaginitis. Differential diagnoses considered included bacterial vaginosis and candidiasis. Treatment with metronidazole 500mg orally twice daily for seven days was prescribed. Patient education regarding safe sex practices, partner treatment, and medication adherence was provided. Follow-up appointment scheduled in two weeks to assess treatment response and rule out reinfection. ICD-10 code A59.0, trichomoniasis, is documented for billing purposes. Patient was instructed to abstain from sexual intercourse until completion of treatment and partner treatment is confirmed. Potential complications, including pelvic inflammatory disease, were discussed.
