What This Code Means

Rheumatoid arthritis affecting the hip (side not specified) along with lung disease from the rheumatoid condition.

Coding Tips

•Use only when hip involvement is documented but the specific side cannot be determined
•Attempt to clarify laterality with the provider, as M05.151 or M05.152 would be more specific

Clinical Significance

This code captures severe rheumatoid arthritis with hip involvement and pulmonary complications when laterality is unspecified, representing systemic disease with significant mobility and respiratory impact. The condition requires comprehensive management addressing both weight-bearing joint function and pulmonary monitoring.

Documentation Requirements

✓Confirmed rheumatoid arthritis with appropriate laboratory findings
✓Documentation of hip involvement without laterality specification
✓Evidence of rheumatoid-related lung disease through clinical studies
✓Clear notation that hip laterality is unspecified or bilateral
✓Clinical assessment establishing connection between RA and lung pathology
✓Mobility and functional capacity evaluation
✓Treatment plan addressing both hip preservation and pulmonary care

Commonly Confused Codes

M05.151 — Rheumatoid lung disease with RA of right hip (specific laterality)M05.152 — Rheumatoid lung disease with RA of left hip (specific laterality)M06.059 — Rheumatoid arthritis of unspecified hip without lung involvement M05.169 — Rheumatoid lung disease with RA of unspecified knee (different joint)M05.10 — Rheumatoid lung disease with RA of unspecified site (joint not specified)
