Biopsy Following Mohs Surgery
I have received conflicting information and would appreciate clarification. I had a patient referred to me by a family physician for a possible basal cell carcinoma. The patient has never had a biopsy. I did a punch biopsy and the diagnostic frozen section which confirmed a morpheaform basal cell carcinoma and performed a stage 2 Mohs procedure 17311 and 17312. Can I bill for the biopsy even when I did the Mohs surgery on the same date?

Answer:
The answer to your question is yes, you can bill the punch biopsy (11105-59) and the frozen section (88331-59) in addition to Mohs surgery. If a biopsy has not been performed within the last 60 days prior to Mohs surgery, you can report the biopsy and frozen section. Make sure you append Modifier 59 to the biopsy and frozen section to identify that the procedure was distinct and separate.

Should the Acupuncturist be Present
When a patient receives acupuncture for 30 minutes, does there need to be personal one-on-one contact with the patient in addition to re-inserting the needles?
Question:
When a patient receives acupuncture for 30 minutes, does there need to be personal one-on-one contact with the patient in addition to re-inserting the needles?
Answer:
CPT coding for acupuncture is based on the time spent actively performing the procedure. This includes selecting the acupuncture points, inserting the needles, monitoring the patient’s response, and making any necessary adjustments. All these tasks require direct interaction with the patient throughout the treatment session. Essentially, the billing code reflects the dedicated time the practitioner spends actively treating the patient, not just the needle insertion itself.
Therefore, yes, the acupuncturist must be present for the entire procedure.

Difference between Preoperative and Postoperative Diagnoses
Is there a difference between a pre-operative diagnosis and a post-operative diagnosis?
Question:
Is there a difference between a preoperative diagnosis and a postoperative diagnosis?
Answer:
Preoperative diagnosis is based on the “reason for the surgery” or the condition affecting the patient leading to the necessity of the surgery. Underlying co-morbidities that can affect the surgical outcome or represent a risk to the patient can also be included but the documentation must support their relationship to the patient risk.
Postoperative diagnoses are based on the findings determined during the surgical procedure. Post-op diagnosis may be the same as the pre-op diagnosis or may be more definitive.

Is Documentation of HPI and Exam Necessary in Determining a Level of E/M?
With the 2021 and 2023 Guideline changes, is it necessary to document an HPI and Exam when neither counts towards the level of service?
Question:
With the 2021 and 2023 Guideline changes, is it necessary to document an HPI and Exam when neither counts towards the level of service?
Answer:
As described in the most recent AMA E/M guidelines, documentation of a history of present illness (HPI) and an exam are no longer required to contribute to the level of an E/M service. Today, documentation of medical decision making, or time are the sole determinants supporting a level of E/M. E/M documentation should include a medically appropriate history and examination. While the nature and extent of the history and exam is to be determined by the clinician, they add to the medical necessity of the visit and provide a more complete representation of the patient condition for continuity and coordination of care with other clinical providers.

Vertebral Segment vs Motion Segment
