0.000What This Code Means
Hodgkin lymphoma of unspecified type affecting lymph nodes within the pelvis.
Coding Tips
- •Verify documentation specifies intrapelvic lymph nodes rather than other pelvic structures
- •Distinguish from other pelvic malignancies that may involve lymph nodes secondarily
Clinical Significance
Hodgkin lymphoma of unspecified type affecting intrapelvic lymph nodes is a deep anatomic location only identifiable on imaging. Intrapelvic nodal disease may cause urinary symptoms, lower extremity edema, or pelvic pain. The unspecified subtype indicates the pathology classification has not been finalized, which should be addressed for optimal treatment planning.
Documentation Requirements
- ✓Confirmed Hodgkin lymphoma diagnosis
- ✓Imaging documenting intrapelvic lymph node involvement (iliac, obturator, presacral nodes)
- ✓Clear distinction from inguinal and intra-abdominal nodes
- ✓Plan for pathology subtype determination
- ✓Encounter-specific assessment and management
Commonly Confused Codes
C81.95 — Hodgkin lymphoma, unspecified, inguinal/lower limb: inguinal is superficial groin; intrapelvic is deep within the pelvisC81.93 — Hodgkin lymphoma, unspecified, intra-abdominal: above the pelvic brim is abdominal; below is pelvicC81.76 — Other Hodgkin lymphoma, intrapelvic: use when pathology classifies as 'other' variant
