| Denial of Care / Authorization Delays |
The defining risk of managed care. When an HMO denies or delays a medically necessary treatment, and the patient is harmed, the organization faces direct liability for the administrative decision — separate from any clinical malpractice. |
Primary driver of managed care liability premiums. Carriers evaluate UR criteria, appeal processes, and external review compliance. |
| Credentialing Failures |
Allowing an unqualified, impaired, or under-credentialed provider to practice within the network. The organization is liable for failing to verify qualifications even if the individual physician is also sued. |
Major underwriting concern; carriers scrutinize credentialing processes, NPDB queries, re-credentialing cycles, and peer review documentation. |
| Multi-Specialty Clinical Operations |
Operating primary care, specialty, surgical, imaging, and lab services under one entity multiplies clinical exposure. Coordination failures between departments are common claim triggers. |
Premiums scale with service scope; each added specialty increases the rate. Surgical services add the most. |
| Utilization Review / Prior Authorization |
Aggressive UR programs that deny or restrict care based on cost rather than medical necessity create bad-faith exposure. External review reversals signal problematic UR practices. |
Premium increase; carriers evaluate denial rates, appeal outcomes, and external review reversal rates. |
| Network Adequacy Issues |
Insufficient specialist availability, long wait times, or geographic gaps in the network can delay care and generate regulatory complaints and lawsuits. |
Regulatory risk; carriers evaluate provider-to-member ratios, geographic coverage, and access standards. |
| Formulary / Drug Coverage Disputes |
Step therapy requirements, prior authorization for medications, or formulary restrictions that delay or deny access to prescribed drugs. |
Growing claim area; carriers evaluate pharmacy benefit management practices and exception processes. |
| Physician Deselection / Termination |
Removing a physician from the network can trigger wrongful termination, anti-competitive behavior, or due process claims — especially if patients are harmed by the disruption. |
D&O and EPLI exposure; requires documented fair hearing and review processes. |
| Regulatory Non-Compliance |
HMOs are heavily regulated by state Departments of Insurance, CMS, and accreditation bodies. Non-compliance can trigger fines, enrollment freezes, or license revocation. |
Regulatory defense coverage essential; carriers evaluate compliance history and accreditation status. |
