Principal Care Management — First 30 Minutes
Care management services for a single high-risk chronic condition expected to last at least 3 months. Covers the first 30 minutes of clinical staff time per calendar month, directed by a physician or other qualified healthcare professional. The focus must be on one principal condition driving the care management need.
Frequency
Monthly (per calendar month)
Time Requirement
Minimum 30 minutes of clinical staff time per calendar month
Documentation Requirements
- Identification of the single high-risk chronic condition being managed
- Documentation of why the condition meets 'high-risk' criteria
- Disease-specific care plan focused on the principal condition
- Time log with date, duration, and description of each PCM activity
- Patient consent for PCM services
- Clinical rationale for ongoing intensive management
Principal Care Management — Each Additional 30 Minutes
Each additional 30 minutes of clinical staff time for principal care management beyond the initial 30 minutes billed under 99424. Requires documentation of continued medical necessity for extended management of the single high-risk condition.
Frequency
Monthly (per calendar month, requires base 99424)
Time Requirement
Each additional 30 minutes beyond initial 99424 time
Documentation Requirements
- Cumulative time log demonstrating total time exceeding 30-minute threshold
- Detailed description of additional care management activities for the principal condition
- Clinical justification for extended management time
- Updated care plan modifications specific to the principal condition
- Reference to base 99424 claim for the same billing period
Eligibility
Patient eligibility.
Patient must have a single high-risk chronic condition expected to last at least 3 months
The condition must be the focus of the care plan and require complex medical management
Patient consent for PCM services must be obtained and documented
An initiating visit must have occurred within the prior 12 months
The condition must place the patient at significant risk of hospitalization, acute exacerbation, functional decline, or death
PCM cannot be billed in the same month as CCM (99490/99439) for the same patient
Avoid These
Common billing mistakes.
Billing PCM in the same month as CCM for the same patient — these are mutually exclusive services
Condition does not meet the 'high-risk' threshold — the condition must pose significant risk of hospitalization, exacerbation, or decline
Insufficient documentation of single-condition focus — the care plan must clearly identify one principal condition, not multiple
Not meeting the 30-minute minimum time threshold before billing 99424
Failing to document why the condition requires intensive management beyond standard E/M services
Using PCM for a patient who would be better served by CCM due to multiple chronic conditions
Compliance
Compliance notes.
PCM is specifically designed for patients with a single complex condition — if a patient has multiple chronic conditions, CCM is generally more appropriate
PCM and CCM cannot be billed for the same patient in the same calendar month
PCM can be billed concurrently with RPM if the monitoring relates to the principal condition
The 3-month expected duration is shorter than CCM's 12-month requirement, making PCM suitable for conditions with uncertain long-term prognosis
Clinical staff can perform PCM services under general supervision of the billing practitioner
PCM requires a condition-specific care plan, not just a general chronic disease management plan
FAQ
Common questions.
What is the difference between PCM and CCM?
The primary difference is the number of conditions managed: PCM focuses on a single high-risk chronic condition, while CCM requires two or more chronic conditions. PCM has a lower duration threshold (3 months vs. 12 months) and a higher initial time requirement (30 minutes vs. 20 minutes). PCM is ideal for patients with one dominant condition that requires intensive management, such as uncontrolled diabetes or advanced heart failure.
Can a patient switch between PCM and CCM from month to month?
Yes, a patient can receive PCM in one month and CCM in another, depending on their clinical needs. However, they cannot receive both in the same calendar month. If a patient initially has one high-risk condition but develops a second qualifying chronic condition, transitioning to CCM may be appropriate. The key is documenting the clinical rationale for the service billed each month.
What conditions typically qualify as 'high-risk' for PCM?
High-risk conditions commonly managed under PCM include uncontrolled diabetes with complications, advanced heart failure (NYHA Class III/IV), COPD with frequent exacerbations, chronic kidney disease stage 3-5, active cancer undergoing treatment, and poorly controlled hypertension with end-organ damage. The condition must place the patient at significant risk of hospitalization, functional decline, or death.
Can RPM and PCM be billed together for the same patient?
Yes, PCM and RPM can be billed concurrently for the same patient in the same month, provided the RPM monitoring relates to the principal condition being managed under PCM. For example, a patient with uncontrolled heart failure could receive PCM for care management and RPM for remote weight and blood pressure monitoring. As with all concurrent billing, time must be tracked separately for each service.
Does PCM require a face-to-face initiating visit?
Yes, PCM requires an initiating visit within the prior 12 months. This can be an Annual Wellness Visit (AWV), Initial Preventive Physical Examination (IPPE), or a face-to-face evaluation and management (E/M) visit. The initiating visit establishes the clinical relationship and identifies the principal condition requiring intensive management.

RPM Billing Guide
Remote Patient Monitoring enables clinicians to monitor patient health data collected via FDA-cleared devices outside of traditional clinical settings. RPM is reimbursed through a set of CPT codes covering device setup, ongoing data transmission, and clinical time spent reviewing and acting on the data.
CCM Billing Guide
Chronic Care Management provides reimbursement for the non-face-to-face care coordination services delivered to Medicare patients with multiple chronic conditions. CCM covers the development and management of comprehensive care plans, medication reconciliation, and coordination across providers and community services.
BHI Billing Guide
Behavioral Health Integration supports the assessment and management of behavioral health conditions within primary care settings through a psychiatric collaborative care model. BHI enables primary care providers to deliver behavioral health services — including depression screening, anxiety management, and substance use disorder monitoring — with psychiatric consultation support.
RTM Billing Guide
Remote Therapeutic Monitoring enables clinicians to monitor non-physiologic data such as therapy adherence, pain levels, medication response, and functional status using FDA-cleared medical devices or software. Unlike RPM (which monitors physiologic data like blood pressure and glucose), RTM is designed for respiratory, musculoskeletal, and cognitive therapy outcomes tracking.
