Abdominal Hernia Defect Size

Question:

Our general surgeon often does not include the size of the abdominal repair in his documentation; can we use the pathology report to determine the correct size for CPT selection?

Answer:

No; the provider must document the hernia defect size within his/her operative report details to accurately select the correct CPT code. The pathology report would likely represent the tissue size, which would not necessarily correlate to the defect size. Best practice is to send a query to the provider asking him/her to add an addendum to the operative report, adding the defect size and advise that this information is required in the documentation.

Reporting An Unlisted CPT Code

Question:

What is needed to report an unlisted CPT code?

Answer:

To report an unlisted CPT code, you must first make certain that no code exists that represents the procedure in its entirety or with a modifier that would represent what was performed (e.g., modifier 52 for reduced services). Once it is determined that there is no existing code to represent the work, choose a code from the appropriate anatomical section of CPT, the appropriate approach (i.e. open vs laparoscopic), and compare the unlisted code to another code that most closely resembles the anatomical area, approach (if possible) and work involved to accurately compare RVUs and reimbursement expectations.

Global period for hernia repair

Question:

Do all hernia repairs have a 90-day global period? 

Answer:

No; inguinal, femoral and lumbar hernias have a 90-day global period. However, abdominal and parastomal hernia repairs have no global period, so E/M and other procedures may be separately reported with appropriate documentation the day following the procedure.

Discrepancy between Procedure Title and Documentation Details

Question:

If the details of a procedure documentation do not match the listed procedure/operation that was planned, which procedure code should be selected?

Answer:

CPT codes are always chosen based on the documentation within the detailed portion of an operative record.  If the details within the body of the report do not match the “procedure title” listed in the beginning of the operative report, the provider should be queried for clarification and a possible addendum to the record if necessary.

Modifier 80 vs 82

Question:

What is the difference between modifier 80 and modifier 82 when a physician is acting as an assistant during surgery?

Answer:

While both modifier 80 and modifier 82 are used when a physician is actively participating as an assistant to a primary surgeon during a surgical procedure, modifier 82 is used in teaching or university hospitals that have approved Graduate Medical Education (GME) programs for Residents. In these teaching hospitals, there must be documentation indicating that no qualified resident was available to assist, to allow for another physician to act as the assistant surgeon, and then modifier 82 is appended to that assistant surgeon.

Pre-op vs Post-op Diagnosis

Question:

Is there a difference between a pre-operative diagnosis and a post-operative diagnosis?

Answer:

Pre-operative 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.

Post-operative 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.
