What 95808 covers

This code describes an attended overnight sleep study that records sleep staging along with one to three additional sleep parameters. Sleep staging uses signals such as EEG, eye movement, and chin muscle activity; additional signals may include airflow, respiratory effort, oxygen saturation, or heart rhythm. A sleep technologist monitors the study, commonly in a sleep laboratory, and a qualified physician interprets the recorded data to assess sleep disorders such as sleep apnea or abnormal sleep behaviors.

Select 95808 when the study is attended and includes sleep staging plus one to three additional parameters. The report and recording documentation should identify the signals obtained, confirm technologist attendance, and support the physician’s interpretation. CMS recognizes separately priced professional and technical components: modifier 26 reports interpretation, modifier TC reports equipment and staff, and no component modifier represents the global service. The billing entity should report the component it furnished.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

95808 billing questions

How is 95808 different from 95810?

Both are attended polysomnography, but 95808 covers sleep staging with one to three additional parameters. Use 95810 for the applicable study with four or more parameters.

When is 95811 used instead?

95811 describes polysomnography with PAP titration. Choose 95808 for a study in its limited-parameter scope without that titration service.

What do modifiers 26 and TC represent?

Modifier 26 identifies the professional interpretation, while TC identifies the technical service, including equipment and staff. Reporting without either modifier represents the global service.

What documentation supports 95808?

The record should show that a technologist attended, identify sleep-staging signals and the one to three additional parameters recorded, and include the physician’s interpretation.

How does 95808 differ from 95807?

95808 includes sleep staging and one to three additional parameters. 95807 is an attended sleep study focused on specified cardiorespiratory measurements rather than sleep staging.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
