Neurology & Pain Management Coding Alert

Question: When I interpret sleep studies (CPAP), I have to reprogram or interrogate the machine when the patient returns for follow-up. Is there a code for this other than a follow-up evaluation and management visit?

Answer: Code 99090 (Analysis of clinical data stored in computers [e.g., ECGs, blood pressures, hematologic data]) can be used to indicate the interpretation of data from the continuous positive airway pressure (CPAP) testing device, while 99091 (Collection and interpretation of physiologic data digitally stored and/or transmitted by the patient and/or caregiver to the physician or other qualified healthcare professional, requiring a minimum of 30 minutes of time) designates both collection and analysis.

Beware: Most payers, including Medicare, include 99090 and 99091 in E/M services, so if you are also performing follow-up care, you should consider other options.

Instead: Let relative value units (RVUs) serve as your guide in opting for general E/M codes 99212-99214 or the more specific 94660 (Continuous positive airway pressure [CPAP] ventilation, initiation and management).

When performing the service in-office, the CPAP management code carries 1.45 RVUs or a national average of $54.95. Unless your physician can document two of three criteria--detailed history, detailed exam, and medical decision-making of moderate complexity--to justify an E/M of at least 99214 (2.18 RVUs for $82.65), 94660 will capture more reimbursement for the CPAP follow-up.
