CPT 99427 Time Requirements
How the Time Works
CPT 99427 covers each additional 30 minutes of clinical staff time. It does not cover the first 30 minutes of PCM services. The first 30 minutes are billed using CPT 99426. After that, CPT 99427 may cover each additional 30-minute period.
Why 99427 Is an Add-On
CPT 99427 is an add-on code because it extends the time reported under 99426. It is not normally billed alone for the initial PCM time. Providers must first meet the time requirements for CPT 99426. Then, they can report 99427 for additional qualifying time.
Why Time Documentation Matters
Accurate time records support the 99427 CPT code on the claim. Documentation should show the services provided and time spent. This helps support the billed time if the claim faces review.
Simple Time Examples
- 30 minutes: Bill CPT 99426.
- 60 minutes: Bill CPT 99426 plus CPT 99427.
- 90 minutes: Bill CPT 99426 plus applicable additional 99427 time.
For example, if clinical staff spend 60 minutes on qualifying PCM work, the first 30 minutes fall under 99426. The next 30 minutes may support CPT 99427 when all billing rules are met.
99427 Documentation Requirements
Proper documentation is important when billing the 99427 CPT code. The records should clearly support the patient, services, staff time, and provider oversight. Documentation should also explain why the additional time was billed.
Patient Eligibility
The record should show that the patient meets PCM requirements. It should identify the condition being managed and support the need for ongoing care management services.
Chronic Condition Being Managed
Documentation should clearly identify the complex chronic condition being managed. The condition should connect directly to the PCM services provided during the billing period.
Disease-Specific Care Plan
The medical record should include a care plan for the patient’s condition. It should explain the care goals and steps used to manage that condition.
Clinical Staff Involvement
Records should identify the clinical staff who provided the services. They should also describe the work completed during the billing period.
Services Performed
Documentation should explain the specific services provided by clinical staff. These may include patient communication, care coordination, monitoring, or other qualifying PCM work.
Total Time
Time records should clearly show the total time spent on qualifying services. The documented time must support the amount reported on the claim.
Additional 30-Minute Time
The records should support the additional 30 minutes billed under 99427. This time should be clearly supported beyond the initial time reported under CPT 99426.
Provider Supervision and Direction
Documentation should show that clinical staff worked under the required direction or supervision of the physician or qualified healthcare professional. This connects the staff services to the responsible provider.
Date and Month of Service
Records should clearly show when the services were provided. The documented service period should match the time and activities reported on the claim.
Keep Documentation Consistent
The claim, time records, and medical record should match. The documented services and time should support the units billed under the 99427 CPT code. Clear records can help support the claim during review or an audit.
CPT 99427 Reimbursement
The 99427 CPT code has a Medicare payment rate for eligible services. However, the amount a provider receives may vary. The final amount can depend on location, payer, and other billing factors.
99427 Medicare Reimbursement
99427 Medicare reimbursement is based on Medicare’s current payment schedule. Medicare updates its payment rates each year. Providers should check the current fee schedule before estimating their expected reimbursement.
The rate listed by Medicare does not always mean that every practice receives the same amount. Different locations can have different payment amounts.
2026 Reimbursement Rate
The 2026 rate for CPT 99427 can vary by location. Medicare adjusts payment rates based on the area where the service is provided. Providers should check the fee schedule for their specific location. This is more accurate than using one national amount for every practice.
In 2026, the national average Medicare payment for CPT 99427 is about $54.11 in a non-facility setting.
National Average vs. Actual Amount
A national average can help estimate 99427 reimbursement. However, it may not match the amount paid on a specific claim.
For example, two practices may bill the same code. One practice may receive a different amount because it operates in another location. Other payer rules can also affect the final amount.
Why Reimbursement Can Differ
Reimbursement can differ between practices for several reasons. Location is one common reason. Medicare and private insurance plans may also use different payment rates.
Private payers may have their own rates for PCM services. Provider contracts can also affect the amount paid.
Patient coverage and claim rules may affect the final amount as well. Therefore, providers should check the current payer rate before estimating revenue from the 99427 CPT code.
99427 vs 99426
