Continuous Glucose Monitor: Provide Supplies for a Calendar Month

We’ve heard from Medicare patients who have a continuous glucose monitor (CGM) that they’ve run out of testing supplies before the end of the month. These patients can’t get traditional testing supplies because they have a CGM.

For example, if a patient gets 2 (14-day) CGM sensors for April, the patient won’t have enough to test on the 29th and 30th.

Here’s how to prevent this serious issue:

  1. Bill the supply allowance (code K0553) as 1 unit of service (UOS) per month. One UOS equals 1 month’s supply (31, 30, 29, or 28 days). You can only bill 1 UOS for code K0553 per month.
  2. Check regularly to see what supplies your patient needs.
  3. Send these supplies to meet the next month’s supply need.

The example below shows how to provide 14-day CGM supplies per calendar month to make sure your patient has enough:

  • April – 30 calendar days: Provide 3 sensors (42-day supply)
  • May – 31 calendar days: Provide 2 sensors (28-day supply) since the patient should have 12 days remaining from the previous month
  • June – 30 calendar days: Provide 2 sensors (28-day supply) since the patient should have 9 days remaining from the previous month

Cognitive Impairment: Medicare Provides Opportunities to Detect & Diagnose

Do you have a patient with a cognitive impairment? Medicare covers a separate visit for a cognitive assessment, so you can more thoroughly evaluate cognitive function and help with care planning.

3 things you need to know:

  1. If your patient shows signs of cognitive impairment at an Annual Wellness Visit or other routine visit, you may perform a more detailed cognitive assessment and develop a care plan
  2. Cognitive Assessment & Care Plan Services (CPT code 99483) typically start with a 50-minute face-to-face visit that includes a detailed history and patient exam, resulting in a written care plan
  3. Any clinician eligible to report evaluation and management services can offer this service, including: physicians (MD and DO), nurse practitioners, clinical nurse specialists, and physician assistants

Effective January 1, 2022, Medicare pays approximately $283 (may be geographically adjusted) for these services when provided in an office setting.
