Frequently Asked Questions

What is medical coding?

Medical coding involves converting diagnoses, procedures, and services into ICD, CPT, HCC, or HCPCS codes for purposes of billing and reimbursement.

HCC refers to the Hierarchical Condition Category risk-adjustment model used to assign reimbursement based on the applicable diagnosis codes.

PCS refers to ICD-10-PCS codes that are used for inpatient procedural services in the hospital setting.

Status codes, assigned by CMS to HCPCS codes, indicate whether a code is eligible for separate payment, bundled, or not payable.

HIPAA-Compliant, Secure & Reliable

Nexus io maintains SOC 2 Type II certification and strict HIPAA compliance across physician billing operations. Patient data protection includes industry-standard security protocols throughout every transaction:
  • 256-bit AES encryption secures patient information during transmission and storage.
  • Multi-factor authentication with role-based access controls limits entry to credentialed staff only.
  • Quarterly security audits and penetration testing identify vulnerabilities before they compromise protected health information.
