1.A pregnant woman who is HIV positive status but is without symptoms - According to this case we have to code HIV without symptoms= Z21, as back pain is not the associated symptom of HIV as mentioned and it is pregnacy related pain we will code as below,
Ans
1. 098.79 = (HIV in pregnancy) Patients with asymptomatic HIV infection status admitted (or presenting for a health care encounter) during pregnancy, childbirth, or the puerperium should receive codes of O98.7- and Z21.
2. M54.9 = back pain (Patient with HIV disease admitted for unrelated condition . If a patient with HIV disease is admitted for an unrelated condition (such as a traumatic injury), the
3.Z21 = Asymptomatc HIV [Do not use this code if the term ?AIDS? is used or if the patient is treated for any HIV-related illness or is described as having any condition(s) resulting from his/her HIV positive
4.Z3A.00 = Number of gestation week, unspecified

1. 098.79 = (HIV in pregnancy)
2. M54.9 = back pain
3. B20 = Symptomatc HIV
4.Z3A.00 = Number of gestation weeks, unspecified.
As reason for encounter takes the priority we will coding according as well as adhering the coding guideline of HIV.
