Diseases of the pelvis, not elsewhere classified

This code captures pelvic pathology that does not fit into more specific ICD-10-CM categories for pelvic disorders. It serves as a residual category for conditions affecting the bony pelvis, pelvic floor, or pelvic structures that lack a dedicated classification elsewhere in the code set. Conditions coded here are distinct from genitourinary, gynecologic, or gastrointestinal disorders that have their own specific chapter assignments.

Apply this code when the documented diagnosis is a pelvic disease or disorder that has been explicitly evaluated and named by the provider, but no more specific ICD-10-CM code exists for that condition. Supporting documentation should include a definitive diagnosis (not just symptoms), with the provider clearly identifying the pelvis as the primary site of pathology. This code is appropriate only after confirming that more specific codes — such as those for pelvic inflammatory disease, pelvic floor dysfunction, or pelvic fracture — do not accurately capture the condition.

• Verify specificity first: This is a true NEC (not elsewhere classified) code; always perform a thorough index and tabular search before defaulting here, as pelvic conditions are scattered across multiple chapters (musculoskeletal, genitourinary, gynecologic).
• Avoid symptom substitution: Do not use this code for unspecified pelvic pain (R10.2–) or other symptom-level presentations; the provider must document a named disease or disorder of the pelvis.
• Laterality and etiology: If the documentation specifies an underlying cause (e.g., post-procedural, infectious, neoplastic), evaluate whether an etiology-specific code or combination code better reflects the condition before assigning this residual category.
