Summary & Overview
HCPCS Level II M1427: Documentation of Medical Reason for Bone Scan
HCPCS Level II code M1427 documents the medical reason(s) for performing a bone scan, such as documented pain related to prostate cancer, salvage therapy, or other clinical indications. Nationally, clear documentation supporting diagnostic imaging is important for clinical decision-making, utilization management, and claims adjudication, making M1427 relevant to radiology services and oncology care pathways. Key payers in typical coverage discussions include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. This publication outlines what HCPCS Level II code M1427 represents, the clinical contexts in which it is used, and the typical sites where bone scans occur. Readers will find concise benchmarks for payer coverage practices, an overview of documentation expectations tied to imaging justification, and the clinical scenarios—particularly prostate cancer-related pain and salvage therapy—where this code is commonly applied. The report also summarizes related coding considerations and common administrative workflows for submitting M1427 on imaging service lines. Data not available in the input is noted where specific payer policies, modifiers, taxonomies, ICD-10 pairings, or related codes would normally be listed.
Billing Code Overview
HCPCS Level II code M1427 documents the medical reason(s) for performing a bone scan, including recorded pain related to prostate cancer, salvage therapy, or other documented medical reasons. This code captures clinical justification in the medical record that supports use of a bone scan as part of diagnostic evaluation or treatment planning.
-
Service type: Diagnostic imaging justification / clinical documentation for bone scintigraphy
-
Typical site of service: Outpatient imaging centers, hospital outpatient departments, or other facilities where bone scans are performed
Clinical & Coding Specifications
Clinical Context
A 72-year-old man with a history of prostate adenocarcinoma presents with new or worsening bone pain and rising prostate-specific antigen (PSA) three years after primary radiation therapy and salvage androgen-deprivation therapy. The treating oncologist documents focal skeletal pain suspicious for metastatic involvement and orders a diagnostic bone scan to evaluate for osseous metastases and to guide further staging and management. The clinical workflow includes: referral from the urology or medical oncology clinic, verification of clinical indication and insurance authorization, scheduling at a nuclear medicine or radiology outpatient imaging center, performance of the radionuclide bone scan by nuclear medicine technologists with acquisition of whole-body planar images (and single-photon emission computed tomography if indicated), interpretation and final report by a board-certified nuclear medicine physician or radiologist, and documentation in the electronic medical record that includes the medical reason(s) for the study (for example, documented pain related to prostate cancer, rising PSA, or post-salvage therapy surveillance). Typical sites of service are outpatient hospital-based radiology departments or freestanding nuclear medicine/imaging centers. The service type is diagnostic nuclear medicine imaging focused on skeletal evaluation.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
25 | Significant, separately identifiable evaluation and management service by the same physician on the same day of the procedure | Use when a qualifying E/M is performed and documented on the same day as the bone scan appointment and is separate from imaging documentation |
