EKG prior to EGD

Federico Posted Thu 27th of March, 2014 11:51:40 AM

In some ocassions an EKG must be performed prior to an EGD/Colonoscopy. Can it be billed separately or is it bundled as part of the procedure?

Bill for pre-operative evaluations using the appropriate Current Procedural Terminology (CPT) code (new patient, established patient or consultation). Pre-operative evaluations often qualify as consultative visits. You can bill a consultation if a surgeon asks you to evaluate a patient's fitness for surgery-even for one of your established patients-if you meet the following criteria:

offer an opinion or advice to the requesting physician and document your opinion;
make a treatment options decision;
perform or order distinctive diagnostic or therapeutic procedures and document them; and
send a written report detailing your opinion and any diagnostic/therapeutic services to the requesting physician.
Medicare requires that you justify pre-operative visits and tests using a diagnosis code that indicates the type of preventive examination and the condition(s) that prompted the surgery. You should select your primary diagnosis from the following ICD-9 codes: V72.81 (pre-operative cardiovascular examination), V72.82 (pre-operative respiratory examination), V72.83 (other specified pre-operative examination), V72.84 (pre-operative examination, unspecified).

List the ICD-9 code indicating the reason for the surgery as the secondary diagnosis. Include on the claim additional diagnoses (or other information) relevant to the pre-operative service(s).

Case study

A general surgeon asks you to determine whether one of your established patients, a 75-year-old female, is able to withstand the general anesthesia required to remove a cancerous colon tumor.

You evaluate the patient in your office, performing a history and physical examination, and pay special attention to her cardiovascular system because she has a history of aortic stenosis. You also order and perform a routine electrocardiogram (ECG) and write a report after interpreting the findings.

You conclude that the anesthesia poses minimal risk to the patient and that the benefit of the surgery exceeds the risks. You send a written report detailing your findings, including recommendations regarding antibiotic prophylaxis, to the operating surgeon.

You would bill Medicare for the appropriate office consultation code and the ECG justifying the pre-operative services according to Medicare's ICD-9 coding requirements. The claim should include:

The appropriate office consultation code, selecting from CPT 99241-99245, and ICD-9 code V72.81 (pre-operative cardiovascular examination to justify the consultation).
CPT code 93000 (ECG with at least 12 leads, interpretation and report) and ICD-9 code V72.81 (pre-operative cardiovascular examination to justify the ECG).
ICD-9 code for colon cancer to explain the reason for the surgery. Use stenosis, a condition complicating the surgery, as supporting justification. Use ICD-9 153.9 (malignant neoplasm, colon) and ICD-9 424.1 (aortic valve disorder-stenosis).

Diagnostic services performed by the ASC may be included in the ASC facility payment. However, if the laboratory of the ASC is not certified, items such as routine simple urinalysis or hemograms should not be billed. Tests performed by a certified ASC laboratory are billed by the laboratory and are separately reimbursable. Similarly, tests performed under an arrangement with an independent or hospital laboratory
are billed directly by the provider. Radiology, EKGs, and other preoperative tests are generally not included in the facility payment when used to determine the suitability of an ASC setting. Other diagnostic and therapeutic tests directly connected to the procedure are included in the facility payment.
