ICD-10-CM Code for Endometrial Calcification
The appropriate ICD-10-CM code for endometrial calcification is N85.8 (Other specified noninflammatory disorders of uterus).
Coding Rationale
Endometrial calcification is a benign finding that does not have a specific dedicated ICD-10-CM code. When a condition lacks a specific code, you must use the most appropriate "other specified" category that captures the anatomic location and general nature of the finding.
Why N85.8 is the Correct Choice:
- N85.8 encompasses "Other specified noninflammatory disorders of uterus" and serves as the catch-all code for benign uterine conditions without dedicated codes
- Endometrial calcification is a noninflammatory structural finding of the endometrium/uterus
- This code is used for documented endometrial abnormalities that don't fit into more specific categories like polyps (N84.0), hyperplasia (N85.0-N85.1), or malignancy
Alternative Codes to Avoid:
- N85.9 (Noninflammatory disorder of uterus, unspecified) - Only use this if the specific finding is truly unknown or undocumented
- N89.8 (Other specified noninflammatory disorders of vagina) - Wrong anatomic location
- E83.59 (Other disorders of calcium metabolism) - This addresses systemic calcium disorders, not localized structural calcification
Clinical Context
Endometrial calcification is typically an incidental imaging finding seen on:
- Transvaginal ultrasound
- Pelvic CT or MRI
- Sonohysterography
Common clinical scenarios include retained products of conception, chronic endometritis sequelae, or degenerative changes. The finding itself rarely requires specific treatment but may warrant evaluation to exclude underlying pathology 1.
Documentation Requirements
For accurate coding, ensure the medical record clearly documents:
- "Endometrial calcification" as the specific finding
- Imaging modality used for diagnosis
- Whether this is an incidental finding or symptomatic
- Any associated conditions (e.g., abnormal uterine bleeding, postmenopausal status)
