Coding references

Orthopedics: the codes and the rules.

Three tables for a orthopedic 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 injection (20610) on the same day as a separately identifiable visit needs modifier 25 on the E/M; the injection alone does not earn a visit.
  • Arthroplasty and arthroscopy carry a 90-day global: routine post-op visits are 99024, and a visit for an unrelated problem in that window needs modifier 24.
  • Fracture care codes (25600, 27786) include the first cast or splint; a replacement cast later is billed separately.
  • Laterality matters in ICD-10-CM: right, left and bilateral are different codes, and payers deny an unspecified side when a specific one exists.
