PCM Billing: CPT Codes and Requirements

Principal Care Management (PCM) is a Medicare care-management service designed for patients who have a single complex chronic condition that requires ongoing management and coordination.

PCM allows eligible healthcare professionals to provide structured, continuous care outside of traditional office visits. When the required services, time, documentation, and patient eligibility criteria are met, providers may bill Medicare using specific CPT codes.

Understanding PCM billing requirements is important because care-management claims depend heavily on patient eligibility, clinical necessity, documented time, care planning, communication, and proper billing practices.

What Is Principal Care Management (PCM)?

Principal Care Management is a care-management program focused on one serious or complex chronic condition that is expected to last at least three months.

The condition should generally:

• Require ongoing medical management
• Create a significant risk of hospitalization or acute deterioration
• Require frequent adjustments or monitoring
• Need a focused care-management approach
• Be addressed through a documented treatment and management plan

Unlike Chronic Care Management (CCM), which generally focuses on patients with multiple chronic conditions, PCM is centered on one complex chronic condition.

Example

A patient may have several health problems, but one condition—such as severe COPD, heart failure, diabetes with complications, or another complex chronic disease—may require the primary focus of ongoing care management.

The PCM service should be connected to that specific condition and the clinical work required to manage it.

PCM CPT Codes

PCM billing primarily uses CPT codes 99424–99427.

99424 and 99425

These codes are used when the PCM service is personally performed by a physician or other qualified healthcare professional.

• 99424: First 30 minutes
• 99425: Each additional 30 minutes

99426 and 99427

These codes are used when the PCM service is provided by clinical staff under the direction of a physician or other qualified healthcare professional.

• 99426: First 30 minutes
• 99427: Each additional 30 minutes

The exact billing requirements and payer policies should always be verified against current Medicare guidance and the applicable payer rules.

What Does PCM Include?

PCM is more than simply making a monthly phone call. The service involves ongoing management of the patient's principal chronic condition.

Depending on the patient's needs, PCM activities can include:

1. Care Plan Development

A comprehensive care plan should identify the patient's principal chronic condition, treatment objectives, interventions, monitoring requirements, and follow-up strategy.

2. Medication Management

The care team may:

• Review medications
• Monitor adherence
• Identify potential medication-related issues
• Coordinate medication changes
• Communicate relevant concerns to the treating provider

3. Monitoring the Condition

The care team may monitor:

• Symptoms
• Clinical changes
• Treatment response
• Patient-reported information
• Relevant measurements
• Warning signs requiring escalation

4. Care Coordination

PCM may involve coordination among:

• Primary care providers
• Specialists
• Hospitals
• Pharmacies
• Other healthcare professionals

5. Patient Communication

Depending on the service and patient's needs, communication may occur through appropriate methods such as:

• Telephone
• Secure electronic communication
• Other permitted communication methods

6. Follow-Up

The care team should follow up on the patient's condition and document clinically relevant activities performed during the month.

PCM Eligibility Requirements

Before billing PCM, the practice should establish that the patient meets the applicable eligibility requirements.

Important considerations include:

One Complex Chronic Condition

PCM is intended to manage one complex chronic condition that requires substantial ongoing management.

Condition Expected to Last

The condition should generally be expected to last for at least three months, or until the condition is resolved.

Significant Risk

The condition should place the patient at significant risk of:

• Hospitalization
• Acute exacerbation
• Functional decline
• Other serious complications

Ongoing Management

The patient should require ongoing medical management rather than a one-time intervention.

PCM Care Plan Requirements

A documented care plan is an important part of PCM.

A practical PCM care plan can include:

The care plan should be individualized to the patient rather than being a generic template.

PCM Time Requirements

Time is an important component of PCM billing.

The practice should track the actual qualifying time spent performing PCM services during the calendar month.

For example:

99424 / 99426

→ First 30 minutes of qualifying PCM service during the month.

99425 / 99427

→ Additional 30-minute increments when the applicable requirements are satisfied.

Example

Suppose qualifying PCM activities total:

• Care coordination: 10 minutes
• Medication review: 8 minutes
• Patient communication: 7 minutes
• Care-plan management: 5 minutes

Total = 30 minutes

The practice may have met the time component for the applicable first-30-minute PCM code, assuming all other billing requirements are satisfied.

Time should not be artificially rounded or manufactured. The medical record should support the services and time reported.

PCM Documentation Requirements

Good documentation is essential for PCM billing and audit readiness.

A PCM record should clearly establish:

Patient Eligibility

Document why the patient qualifies for PCM and identify the principal chronic condition being managed.

Medical Necessity

Explain why ongoing care management is clinically necessary.

Care Plan

Maintain an individualized plan addressing the patient's condition and management needs.

Services Performed

Document the actual activities performed during the month.

Time

Record qualifying time in a manner that supports the billed CPT code.

Communication

Document relevant communication with the patient, caregivers, providers, specialists, or other healthcare professionals when applicable.

Clinical Updates

Record meaningful changes in the patient's condition, treatment, medications, or care plan.

Patient Consent

Patient consent requirements should be addressed before providing and billing applicable care-management services.

The practice should maintain documentation showing that the patient was informed about:

• The nature of the PCM service
• The purpose of the service
• Applicable cost-sharing
• Relevant billing considerations
• The patient's ability to discontinue the service

Practices should follow the current Medicare and payer-specific consent requirements rather than relying on an outdated workflow.

Who Can Perform PCM?

PCM can involve different members of the healthcare team depending on the CPT code and applicable rules.

Physician / Qualified Healthcare Professional

Certain PCM services may be personally performed by the physician or other qualified healthcare professional.

Clinical Staff

Other PCM services may be performed by clinical staff under the direction of the physician or qualified healthcare professional.

A practice-management system should therefore identify:

Who performed the activity → What was performed → When it was performed → How much qualifying time was spent → Which provider supervised or directed the service when required.

PCM Billing Workflow

A well-designed PCM workflow can follow this sequence:

Patient Identification
↓
Verify PCM Eligibility
↓
Identify Principal Chronic Condition
↓
Document Medical Necessity
↓
Obtain/Document Required Consent
↓
Create PCM Care Plan
↓
Perform Monthly PCM Activities
↓
Track Qualifying Time
↓
Document Each Activity
↓
Monthly Review
↓
Validate CPT Requirements
↓
Submit Claim
↓
Process ERA/EOB & Payment

This workflow helps connect clinical documentation with billing requirements.

PCM vs. CCM

PCM and CCM are related care-management services, but they are not identical.

The correct program should be selected based on the patient's clinical situation and the applicable billing rules.

Common PCM Billing Mistakes

Practices should avoid the following problems:

1. Billing Without Confirming Eligibility

Do not assume every patient with a chronic condition automatically qualifies for PCM.

2. Missing the Principal Condition

The documentation should clearly identify the one complex chronic condition being managed.

3. Incomplete Care Plan

A generic or incomplete care plan may create documentation problems.

4. Unsupported Time

The documented time should support the billed service.

5. Copy-and-Paste Documentation

Repeated identical notes may fail to demonstrate meaningful ongoing care.

6. Poor Activity Tracking

If the system does not capture who performed an activity, when it occurred, and what was done, billing validation becomes difficult.

7. Ignoring Payer Rules

Medicare requirements can differ from commercial payer policies. Practices should verify applicable payer rules before submitting claims.

How Software Can Simplify PCM Billing

A modern EHR or practice-management system can automate much of the PCM workflow.

Useful PCM features include:

• PCM eligibility checklist
• Principal-condition selection
• Care-plan templates
• Consent tracking
• Monthly activity tracking
• Automatic time accumulation
• Provider/staff attribution
• Monthly review
• CPT eligibility alerts
• Documentation validation
• Claim generation
• Billing-status tracking
• ERA/EOB integration
• Audit-ready activity history

Example PCM Dashboard

A PCM dashboard could display:

Patient: John Doe
Principal Condition: Complex Chronic Condition
Monthly Time: 24 / 30 minutes
Care Plan: Active
Consent: Documented
Medication Review: Completed
Care Coordination: 2 activities
Patient Contact: Completed
Monthly Review: Pending
Billing Status: Not Ready

This gives the care team and billing department a clear view of what remains before the claim is submitted.

PCM Billing Documentation Checklist

Before submitting a PCM claim, verify:

☑ Eligible patient
☑ One principal complex chronic condition identified
☑ Medical necessity documented
☑ Required consent documented
☑ Individualized care plan established
☑ Qualifying services performed
☑ Actual qualifying time documented

☑ Claim reviewed before submission

Conclusion

Principal Care Management (PCM) provides a structured way to manage patients with a single complex chronic condition through ongoing monitoring, care coordination, treatment management, and patient engagement.

For successful PCM billing, practices should focus on four core areas:

Eligibility + Care Plan + Qualifying Services/Time + Complete Documentation

Using a well-designed EHR and billing workflow can make it easier to track monthly activities, validate CPT requirements, reduce documentation gaps, and maintain an audit-ready record.

Important: CPT codes, Medicare rules, coverage policies, and payer requirements can change. Practices should verify current CMS and payer guidance before billing.
