Coding references

General and family medicine: the codes and the rules.

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

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

The notes a coder repeats.

  • G2211 (0.33 work RVUs) is Medicare's add-on for the visit that anchors an ongoing relationship; it is not reported with modifier 25 on the same claim.
  • A preventive visit and a problem visit on the same day are both billable when the problem work is significant and documented separately (modifier 25 on the E/M).
  • Chronic care management (99490, 99439) and transitional care management (99495, 99496) are time-based codes that need the practice's call log and care plan as documentation.
