Pulmonology Coding Alert

The new Correct Coding Initiative (CCI) revision contains several code edits that rely on the correct use of modifier -59 to capture appropriate reimbursement, and says retroactive reimbursement may be appropriate in some cases. Modifier -59 (distinct procedural service) must be used correctly to support billing separately and obtaining appropriate reimbursement for unrelated procedures performed on the same patient on the same day.

The Health Care Financing Administration (HCFA) issued an updated CCI, Version 6.1, which became effective April 1, 2000. To make sure you receive the maximum reimbursement allowed for services, its crucial that you understand when and how to use modifiers; the CCI includes several edits that refer to modifier -59.

Procedures performed at different sites appropriately may use modifier -59. The CCI will reflect HCFAs edit that code 31629 (bronchoscopy, with transbronchial needle aspiration biopsy) should be allowed with 31628 (with transbronchial lung biopsy, with or without fluoroscopic guidance) as long as the transbronchial needle aspiration biopsy is performed on a lesion other than the one coded as 31628. In this situation, the 31628 and the 31629 should be billed with modifier -59 attached to the second procedure. (See CCI Edits Affect Pulmonology Coding on page 28.) HCFA will allow you to submit retroactively, dating back to Oct. 1, 1998, for reimbursement for CPT codes 31628-31629 appended with modifier -59. Medical billing consultant Don Self, CCS, BFMA, president of Don Self & Associates, a practice management and billing specialist in Whitehouse, Texas, suggests the simplest way to handle this is to file a new claim for the services.

If the carrier denies the claim as being bundled, advises Self, appeal the claim with a copy of the HCFA memorandum, and you should win without any problem.

Deborah Anderson, a billing consultant with Salem Pulmonary Associates, a physician billing office in Salem, Ore., says the patient encounters can take place on the same day as long as the documentation shows they were done separately.

For example, she says, Its appropriate to bill for a 94010 (spirometry, including graphic record, total and timed vital capacity, expiratory flow rate measurement[s], with or without maximal voluntary ventilation) done the day before or on the same morning of the afternoon 94070 (prolonged postexposure evaluation of bronchospasm with multiple spirometric determinations after antigen, cold air, methacholine or other chemical agent, with subsequent spirometrics]) is performed.

Modifier -59 lets the insurance company know that a separate procedure from the methacholine testthe spirometry, in this instancewas performed. She stresses that its also critical to document the amount of time [...]
