Using ICD Coding for Billing Purposes

Coding Case

1. The potential ICD-10 codes for this case may include:

· N76.0 Acute vaginitis

· N76.1 Subacute and chronic vaginitis

· N39.0 Urinary tract infection, site not specified

· Z30.09 Encounter for initial prescription of other contraceptives

· Z87.891 Personal history of appendectomy

· Z83.41 Family history of diabetes mellitus

2. When a patient seeks care at a clinic or medical practice, the provider will typically document the patient's medical history, including any previous visits or encounters. This medical record serves as a repository of information about the patient's health and care, including diagnoses, treatments, medications, and other relevant information. When a patient returns to the clinic or medical practice for follow-up care, the provider can review the patient's medical record to see what has been documented previously. If the patient has been seen at the clinic before, the provider can use this information to guide their evaluation and management of the patient. The provider can also use this information to determine if the patient is a new or established patient for billing and coding purposes. In general, a patient is considered a new patient if they have not received any services from the provider within the past three years (Bajowala et al., 2020). If the patient has been seen by the provider within the past three years, they are considered an established patient. This distinction is important for billing and coding purposes, as different codes and reimbursement rates may apply depending on whether the patient is a new or established patient.

2. The components of care that will be used for reimbursement decision for Ms. Ward may include:

· History of Present Illness

· Review of Systems

· Past Medical, Family, and Social History

· Physical Examination

· Laboratory Tests

· Diagnosis and Treatment Plan

4. The type of physical examination level that best fits what was performed on Ms. Ward is a Level 3 Expanded Problem Focused Examination. The NP performed a focused examination of the patient's GU system and documented her findings in the medical record. A Level 3 Expanded Problem Focused Examination is a type of physical examination that includes a focused examination of a limited number of body systems or regions, typically related to a specific problem or symptom. In Ms. Ward's case, the NP performed a focused examination of the patient's genitourinary (GU) system, specifically examining the external genitalia, cervix, and performing a bimanual examination to assess for any adnexal masses or tenderness. The NP also documented the presence of a thick white vaginal discharge and noted the findings of the wet mount, whiff test, and clue cells in the medical record. Thus, based on these elements, a Level 3 Expanded Problem Focused Examination is the most appropriate code to use for billing and coding purposes in this case (Huang et al., 2019).

5. To determine the decision-making level for coding the visit, the NP would consider the number and complexity of the problems addressed during the encounter, the amount and complexity of data reviewed and analyzed, and the risk of complications or morbidity from the patient's presenting problem. In this case, the NP addressed one problem (vaginal discharge and UTI), reviewed and analyzed moderate amount and complexity of data from laboratory tests, and the risk of complications or morbidity was moderate. Therefore, the NP would choose a moderate complexity level of decision-making (Level 2) for coding the visit.
