Question: A patient presents with calf pain and the physician orders a STAT ultrasound to rule out deep vein thrombosis (DVT). Following the review of the test results, the physician later documents that the patient is stable enough that there is no concern for pulmonary embolism. Does this scenario meet a moderate MDM ( 99214 , 99204 ) based on the number and/or complexity of problems addressed and risk of complications and/or morbidity or mortality of patient management due to the need to initiate or forego further testing, treatment, and/or hospitalization? ...

Article Overview
This article is a coding guidance Q&A focused on evaluating medical decision making when a clinician orders urgent diagnostic testing for a patient with calf pain and possible thromboembolic concern. It is useful for coders, auditors, and billing staff working with CPT-based office/visit documentation, especially when reviewing how risk is assessed and documented in relation to diagnostic workup and later test results. The piece also points readers to CPT 2022 medical decision making guidance and CPT 2021 errata/technical corrections for clarification.
Why This Topic Matters
It helps readers understand that coding risk assessment depends on the physician’s initial evaluation and documentation, not simply the final test outcome, which can affect visit level selection and audit readiness.
What You Will Learn
- How this scenario is evaluated under CPT medical decision making concepts
- How urgent diagnostic testing factors into risk assessment at the time of the visit
- Why later test results do not necessarily change the original level of documented complexity
- Where to look for related CPT guidance and corrections
