About coding transient synovitis
The ICD-10-CM code for transient synovitis is M67.3 (Transient synovitis). The official index lists 11 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on M67.3.
Within M67 (other disorders of synovium and tendon), M67.3 is specifically for transient synovitis. Related codes cover short Achilles tendon (acquired) (M67.0), Synovial hypertrophy, not elsewhere classified (M67.2), ganglion (M67.4), Plica syndrome (M67.5), other specified disorders of synovium and tendon (M67.8), unspecified disorder of synovium and tendon (M67.9) and plantar fasciitis (M67.A).
To report this condition, pick the subcode that matches the documentation: M67.30 (unspecified site), M67.31 (shoulder), M67.32 (elbow), M67.33 (wrist), M67.34 (hand), M67.35 (hip), M67.36 (knee), M67.37 (ankle and foot) and 2 more.
Don't report M67.3 together with the conditions in its Excludes1 note: palindromic rheumatism (M12.3-).
