As auditors/educators, we sometimes encounter scenarios where the coding just does not “feel right.” Unless we have a coding guideline or credible source to validate us, our “feeling” doesn’t matter.
There was a recent post on social media. The poster was concerned that a provider did not document an examination for an established patient. The provider documented a Detailed History and Moderate Complexity MDM to support the E/M level.
We all know that an established patient visit only requires documentation of two of the three Key Components, and everyone who responded was in agreement. Some added comments about coding based upon time, but the original post did not indicate the documentation supported time-based coding.
What made me pause, were comments that a physical examination is not needed for an established patient. This is inside the mind of a medical coding auditor, so here are my thoughts:
- What condition(s) (nature of presenting problem(s))would an established patient have that requires a detailed history and moderate medical decision-making, but does not require an examination of the problem-pertinent body area/organ system?
It was the detailed history that bothered me. I mentally processed several scenarios and could not think of one. According to any documentation on billing and coding published by CMS, medical necessity, rings in my head. “The provider must ensure that medical record documentation supports the level of service reported to a payer. You should not use the volume of documentation to determine which specific level of service to bill.”1
So, these were my mental scenarios:
- Established patient presented for results of studies ordered during the last visit.
- Established patient presented for follow-up of chronic condition(s).
- Established patient presented for new complaint(s).
At that moment, it clicked.
CMS guidance for Evaluation and Management Services do NOT specify a physical examination must be one of the two Key Components for an established patient.
There’s nothing in the Medicare Claims Processing Manual that states examination must be one of the two key components for an established patient visit.
Therefore, it doesn’t matter that IMHO, the provider should document an examination, if it’s the provider’s clinical judgment that an examination is not medically necessary.
