Coding references

Cardiology: the codes and the rules.

Three tables for a cardiology practice, each one a coder can check against the 2025 CMS and ICD-10-CM files, and the notes that come up every week.

2025 files

Reference, not billing advice. The practice's coder confirms every code before a claim goes out.

The tables.

The notes a coder repeats.

  • An ECG interpreted in the office is 93000 (tracing and read); a tracing done elsewhere and read here is 93010.
  • Echo and stress codes are complete services; when the practice bills only the professional component it appends modifier 26.
  • Device checks have frequency limits (for example one remote pacemaker interrogation per 90 days); the schedule should keep the interval.

Screening forms your clinicians approve, the on-call paged with answers, and every call booked or handed back as a task.
