## **What is HCPCS Code M1153?**
The HCPCS Code M1153 is a Level II Healthcare Common Procedure Coding System (HCPCS) code that identifies a patient with a diagnosis of osteoporosis on the date of the encounter. It falls under the “Other Services” category and is primarily used for quality reporting rather than to reflect encounter complexity or provider time.
This code is commonly used in Medicare quality programs, such as the Merit-based Incentive Payment System (MIPS) Measure #039 (Osteoporosis Screening in Older Women). In these measures, M1153 serves as a denominator exclusion, meaning that if a patient has an established diagnosis of osteoporosis, they are excluded from screening requirements. Instead, the focus is typically on documenting the diagnosis and ensuring appropriate treatment and ongoing management of osteoporosis.
## **HCPCS code M1153 documentation requirements**
Providers must ensure the medical record clearly reflects that the patient has an active and documented diagnosis of osteoporosis on the encounter date.
Key documentation elements include:
- Evidence in the medical record of osteoporosis, such as a problem list entry, diagnostic test results, or specialist notes.
- Confirmation that the diagnosis applies during the relevant measurement period or performance period.
- Documentation of any exclusions that apply, such as the patient receiving hospice services.
- Patient demographics, particularly for female patients and women in at-risk age groups, since M1153 is often used in the context of osteoporosis screening measures.
Accurate documentation supports compliance with CMS quality reporting and ensures that patients are correctly identified in performance metrics.
## **HCPCS code M1153 billing requirements**
Billing for M1153 does not involve additional reimbursement or complexity-based payment. Instead, it functions as a status/reporting code to standardize how patients with osteoporosis are tracked across encounters.
Billing requirements include:
- Reporting M1153 alongside the appropriate CPT Evaluation & Management (E/M) service code when a patient with osteoporosis is seen.
- Ensuring the osteoporosis diagnosis is documented in the medical record on the date of service.
- Using the code to indicate that the patient should be excluded from osteoporosis screening measures, since they already have the condition.
- Following payer-specific guidelines for including M1153 in quality reporting for the applicable measurement period or performance period.
Because it is a reporting code, M1153 is not separately reimbursed under Medicare Part B. Instead, it ensures accurate quality reporting and helps avoid unnecessary screening claims for patients who already carry an osteoporosis diagnosis.
