Clinical Context
A 78-year-old patient with multiple chronic conditions — congestive heart failure, type 2 diabetes mellitus with neuropathy, and chronic obstructive pulmonary disease — presents for monthly complex chronic care management. The treating physician (or other qualified healthcare professional) performs a comprehensive care plan review and active management that requires more than the initial 30 minutes of direct practitioner time in the calendar month. The workflow includes review of recent hospital discharge summaries and medication lists, remote monitoring data review (weight, blood glucose, pulse oximetry), coordination with the home health nurse and cardiology, adjustment of medications, documentation of a revised problem list and goals, and synchronous or asynchronous communication with the patient and caregivers. The clinician documents cumulative time spent personally managing the patient for the month, and after the first 30 minutes bills 99437 for each additional 30-minute increment when the clinical complexity and coordination exceed the base time allowance.
Coding Specifications
| Modifier | Description | When to Use |
|---|
25 | Significant, separately identifiable E/M service on the same day | Use when a distinct E/M visit unrelated to the chronic care management time occurs the same day. |
| 22 | Increased procedural services | Use when the complexity or intensity of management substantially exceeds typical requirements and documentation supports increased work.
| 52 | Reduced services | Use when the service was provided at less than full scope or was partially reduced or canceled.
| 53 | Discontinued procedure | Use when the management activity was started but discontinued due to patient factors.
| 62 | Two surgeons/lead surgeon | Use when two physicians share active management responsibility and payor allows split/shared reporting rules.
| 80 | Assistant surgeon | Rarely used; apply when an assistant participates in hands-on care that is billable under specific payer rules.
| 82 | Assistant surgeon (when qualified resident not available) | Use if an assistant is required and documentation supports use instead of a resident assistant.
| 78 | Unplanned return to the operating room by the same physician following initial procedure | Generally not applicable but included when subsequent operative management affects overall chronic care planning.
| AS | Physician assistant, nurse practitioner, or clinical nurse specialist services in certain settings | Use to indicate services furnished by an APP when permitted by the payor and local coverage rules.
| QK | Medical direction of two, three, or four assistants | Use when the billing physician directed assistants meeting Medicare medical direction rules.
| QX | Certified registered nurse anesthetist (CRNA) service: CRNA with medical direction | Included for completeness when anesthesia services intersect with complex chronic care management needs.
| QY | Medical direction of one CRNA by a physician | Similar context as QX when applicable.
| 29 | Professional component | Use if reporting only the professional component of a service that has a split technical/professional component.
| 23 | Unusual anesthesia | Use when anesthesia is required unusually and affects the overall complexity of care planning.

Related CPT Codes
| CPT Code | Description | Relationship to This Procedure |
|---|
99490 | Chronic care management services, at least 20 minutes of clinical staff time directed by a physician or other qualified health care professional per calendar month, with chronic conditions | Often billed for lower-intensity monthly chronic care management when staff time (not physician time) meets the minimum; 99437 applies to additional physician/qualified professional time beyond initial 30 minutes. |
| 99439 | Chronic care management services, each additional 20 minutes of clinical staff time directed by a physician or other qualified health care professional per calendar month (List separately in addition to code for primary service) | Used for additional staff time increments; pairs with primary CCM codes when extra staff resources are required alongside physician management.
| 99487 | Complex chronic care management services, first hour of clinical staff time directed by a physician or other qualified health care professional per calendar month; moderate or high complexity medical decision making | Represents the intensive care management service for complex patients; may be used in care plans where higher complexity is met and physician time complements staff-directed services.
| 99489 | Each additional 30 minutes of clinical staff time directed by a physician or other qualified health care professional, per calendar month (List separately in addition to code for primary service) | Used for additional staff time in complex CCM; complements physician time billed with 99437 when both staff and physician time exceed base units.
| 99495 | Transitional care management services with moderate complexity (interactive contact within 2 business days and face-to-face within 14 days) | Frequently performed after hospital discharge in the care continuum; documentation of transitional care activities may overlap with monthly care plan management and coordination.
| 99496 | Transitional care management services with high complexity (interactive contact within 2 business days and face-to-face within 7 days) | Used for higher complexity post-discharge management; relevant when intensive post-acute coordination is part of the monthly management time.
