Know which modifiers to use with 95807 To ensure reimbursement for your pulmonologist's sleep-disorder treatments, you should know the difference between sleep studies (95805-95807) and polysomnography (95808-95811) or expect the denials to start rolling in. If you report sleep testing (95805-95807), you should know that your pulmonologist will not stage the study and that the patient could be awake. 2. Use 95808-95811 for Staged Studies Before you assign polysomnography codes 95808-95811, remember that Medicare insurers require your pulmonologist both to record and stage a patient's sleep. Therefore, the medical documentation should include that the physician staged and recorded the patient's sleep. Don't leave your sleep study and polysomnography vulnerable to denials by not documenting where the tests occurred and who attended them, coding experts say.
Although the services are similar, pulmonologists perform sleep studies and polysomnography as separate diagnostic tests, and you can separately report these tests if you prove medical necessity, says Marvel J. Hammer, RN, CPC, CHCO, owner of MJH Consulting, a healthcare reimbursement consulting firm in Denver.
Experts offer three strategies to keep your eyes wide- open when reporting sleep studies and polysomnography.
1. Report 95805 for Wakefulness Testing
Typically, you will code sleep studies when the pulmonologist treats conditions such as sleep apnea (780.5x), narcolepsy (347), and acute respiratory failure (518.81). You can choose from three CPT codes:
Sleep staging includes a one-to-four-lead electroencephalogram, an electroculogram, nasal and oral airflow, ventilation, and respiratory effort. The physician may include other tests, such as a submental electromyogram, says Susan Turney, MD, FACP, medical director of reimbursement at the Marshfield Clinic in Marshfield, Wis.
You can choose from three polysomnography codes, which you use differently depending on the number of parameters and other tests:
3. Document Test Location and Time
For instance, insurers will not pay for home-based sleep studies (95806), because a physician or technologist can't supervise them, and insurers don't find them medically necessary. And, if you submit an in-facility code, such as 95807 or 95810, you should attach modifier -26 (Professional component) because the technologist and lab should document physician or technologist attendance.
On the other hand, when you report the global code for services provided in your lab, you must specifically document that a physician or technologist attended.
When you report sleep studies or polysomnographies, make sure they lasted a minimum of six hours, Turney says. If the tests last less than six hours, you should report the code with modifier -52 (Reduced services).
