Remote patient monitoring

About 99458: Remote physiologic monitoring management, each additional 20 minutes

Report this add-on for each additional full 20 minutes of remote physiologic monitoring treatment management in a calendar month beyond the first 20 minutes reported with 99457.

This service covers extended management time when a physician, other qualified health care professional, or clinical staff reviews readings from a remote physiologic monitoring device and acts on them. Typical devices include blood pressure cuffs, weight scales, glucometers, and pulse oximeters used by patients with hypertension, heart failure, diabetes, or COPD. The work can include reviewing transmitted readings, coordinating care-plan changes, and communicating with the patient or caregiver. Primary care, cardiology, and endocrinology practices commonly provide this service, including through clinical staff working under general supervision.

Management time accumulates across the calendar month. The first 20 minutes, including at least one real-time interactive communication, are reported with 99457. Each additional full 20 minutes supports one unit of 99458: a month with 60 total minutes supports 99457 plus two units of 99458. Remaining time short of another 20 minutes does not support another unit. Documentation should identify dates, minutes, personnel, and management activities. As an add-on code, 99458 is reported with its primary code, 99457, rather than alone, and CMS pays it within the primary service's global period.

99458 billing questions

Can 99458 be billed without 99457?

No. It is an add-on that requires 99457 for the same patient and calendar month, after the first 20 minutes of management time are complete.

How many units of 99458 can be reported in a month?

Report one unit for each additional full 20 minutes of management time beyond the first 20 minutes. A total of 40 minutes supports one unit; 60 minutes supports two.

Do partial minutes count toward another unit?

No. A unit requires a full additional 20 minutes; for example, 55 total minutes supports 99457 plus one unit of 99458.

Can clinical staff time count toward 99458?

Yes. Medicare allows documented management time by clinical staff under general supervision of the billing practitioner.

Can the same minutes count toward chronic care management and 99458?

No. RPM and chronic care management may be reported in the same month, but each minute can be counted toward only one service.

Does management time reset each calendar month?

Yes. Tally management time separately for each calendar month to determine whether 99457 and any units of 99458 are supported.
