M17.10

Billable

Unilateral primary osteoarthritis, unspecified knee

This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).

What This Code Means

Osteoarthritis affecting one knee that develops naturally over time, but the specific knee (left or right) is not documented.

Coding Tips

  • •This code should only be used when laterality cannot be determined; attempt to query the provider for M17.11 or M17.12
  • •Confirm the osteoarthritis is primary (age-related) rather than secondary to trauma or other conditions
