The ICD-10-CM diagnosis code R19.09, categorized under “Other intra-abdominal and pelvic swelling, mass and lump,” is a billable code used for medical diagnosis and insurance reimbursement. This code is effective for diagnoses made on or after October 1, 2015, with the latest 2025 edition taking effect on October 1, 2024. It is a specific code within the American ICD-10-CM system; international versions may vary.

Understanding R19.09 and Adnexal Mass
The term “adnexal mass” is explicitly listed as an approximate synonym for R19.09. This is crucial because “adnexal mass” refers to a mass located in the adnexa of the uterus, which includes the ovaries, fallopian tubes, and surrounding connective tissues. Therefore, when a patient presents with an adnexal mass, and further specificity is not yet determined, diagnosis code R19.09 becomes highly relevant for initial coding.
Other synonyms associated with R19.09 broaden its application to include terms like “groin mass,” “inguinal mass,” “pelvic mass,” and “retroperitoneal mass.” This indicates the code’s utility in capturing a range of non-specific masses and swellings within the abdominal and pelvic regions when a more precise diagnosis is pending. It’s also applicable to “pelvic mass in pregnancy,” acknowledging its use in obstetric contexts.
Annotations and Related ICD-10-CM Codes
ICD-10-CM codes like R19.09 often contain annotations that provide further guidance. These annotations, termed “back-references,” link R19.09 to other codes through:
- Applicable To annotations: Contexts where R19.09 is appropriately used.
- Code Also annotations: Codes that should be used in conjunction with R19.09 to provide a more complete clinical picture.
- Code First annotations: Instructions on sequencing R19.09 with an underlying condition.
- Excludes1 and Excludes2 annotations: Clarifications on conditions that should or should not be coded with R19.09.
- Includes annotations: Conditions explicitly included under the R19.09 category.
- Note annotations: Additional instructions or clarifications regarding the use of R19.09.
- Use Additional annotations: Guidance to use supplementary codes for further details.
These annotations are essential for accurate and comprehensive medical coding, ensuring that R19.09 is used correctly within the broader ICD-10-CM framework. Reviewing these annotations in official ICD-10-CM resources is recommended for precise application.
Code History and Context within ICD-10-CM
R19.09 was introduced as a new code in 2016 (effective October 1, 2015) and has remained unchanged through the 2025 edition. This stability indicates its established place within the diagnostic coding system.
R19.09 falls under the broader category R19 “Other symptoms and signs involving the digestive system and abdomen” and the subcategory R19.0 “Intra-abdominal and pelvic swelling, mass and lump.” It is positioned within a hierarchy of codes that become increasingly specific, moving from general abdominal and pelvic findings (R19.0) to more localized descriptions such as “Right upper quadrant abdominal swelling, mass and lump” (R19.01) and “Left lower quadrant abdominal swelling, mass and lump” (R19.04), among others. R19.09 serves as a catch-all for “Other” intra-abdominal and pelvic masses that are not specified by the more detailed codes in the R19.0 series.
Conclusion
In summary, diagnosis code R19.09 is a crucial tool in medical coding, particularly when dealing with adnexal masses and other non-specific intra-abdominal or pelvic masses. Its inclusion of “adnexal mass” as a synonym highlights its relevance in gynecological diagnoses. Understanding its context within the ICD-10-CM system, its annotations, and its code history are vital for healthcare professionals and medical coders to ensure accurate and effective use for diagnosis and reimbursement purposes. Using R19.09 appropriately ensures that patient conditions are correctly documented and that healthcare providers are accurately compensated for their services.
