Policy Letter (important, please read):

West Denver Endocrinology is a "micropractice." Micro-practitioners operate in small unconventional clinics with minimal support staff, relying on computer systems or contract services to manage most tasks outside of direct patient care. By operating in this way, overhead is minimized, efficiency is improved, and the clinician regains time with patients. West Denver Endocrinology’s mission is to enhance and prioritize the clinician-patient element to deliver exceptional medical care that is patient centered, safe, and timely.

West Denver Endocrinology is an adult outpatient Endocrinology specialty clinic. Only endocrine concerns or other metabolic, nutrition, or hormonal abnormalities are addressed. Patients are required to maintain a primary care provider (PCP) to assist in “non-Endocrine” healthcare. Patients assume associated risks if they involve an Endocrinology clinician in care outside of an Endocrinology clinicians’ scope of practice.

Only prescriptions necessary for hormone replacement or treatment of endocrine disease are prescribed. West Denver Endocrinology clinicians do not prescribe opioids or benzodiazepine medications. Also, West Denver Endocrinology LLC is not equipped to handle medical emergencies. For a medical emergency call 911 or report to the nearest emergency room.

Patients are expected to obtain a referral for initial consultation. If health insurance coverage is denied due to failing to get a referral, the patient will be required to pay full cost of appointment. To make your visit as productive as possible we may require you to supply lab work or other information about your Endocrine concern for your appointment(s) or may request records from other (or prior) care providers.

West Denver Endocrinology provides a comfortable waiting room stocked with reading material and refreshments. Although a staff person is not available to greet patients at the door, patients are expected to arrive by their appointment time and make themselves comfortable while waiting for a Clinician. Depending upon patients’ needs a telehealth video chat may be offered in lieu of an in-person appointment. If the appointment type needs to be changed from "in-person" to "telehealth," 24 hours advance notice is preferred.  Out of respect for patients who arrived on time, late arrivals will be asked to reschedule or may choose to be seen after on-time patients have completed their appointments. Patients are expected to attend every appointment as scheduled.
You will be billed a $50 cancellation fee if you fail to provide at least 24 hours advance notice of cancellation. Repeatedly arriving late for appointments, more than 2 “no shows,” failure to attend a new patient consult, or other attendance policy violations may also result in dismissal from West Denver Endocrinology.

Vaccine eligible patients are expected to be fully immunized. West Denver Endocrinology clinicians do not offer vaccine exemptions.

Although a clinician is nearly always available via phone, e-mail, etc..., it is still critically important to follow up with patients face to face (in person or video chat). Please adhere to the recommended visit frequency outlined in your care plan. Prescriptions and test orders will not be provided to patients not attending appointments and some insurers require patients to attend regular clinic visits to receive coverage of medications or medical supplies. Patients who cannot comply with attending recommended appointments or fail to maintain a primary care physician may be asked to find a new Endocrinologist.

It is the patient’s responsibility to ensure timely receipt of all test results. Patient’s will contact their provider within 7 days of obtaining testing to receive results (if results are not already received).

72 hours is required for prescription refills. Please be aware of your medication needs and allow time to get your prescriptions filled. Prescriptions are crucial to your health and well-being; please call your pharmacy for your refills well in advance of running low. Be aware that many prescriptions need to be authorized by your insurance company. Authorizations are completed in a timely manner, but it takes days to weeks to receive an insurance authorization.

West Denver Endocrinology will not dismiss a “non-compliant” patient who attends all appointments and demonstrates a genuine willingness to work with a clinician to address and overcome barriers to treatment plan compliance; however, the
patient assumes all responsibility for bad outcomes due to non-compliance and any patient who willfully violates West Denver Endocrinology LLC policies, misuses or abuses medication, is verbally abusive to a clinician or staff, or threatens a clinician or medical assistant will be permanently terminated from care at West Denver Endocrinology LLC.

Fees are billed for all services provided. Patients are expected to check with insurer prior to attending an appointment to verify services are covered. Prompt payment for services is expected. A fee schedule is available upon request. Patient is expected to pay copay amount deemed owed by insurance company on the day of appointment. Patients also reserve the right to forgo insurance billing and pay self-pay price. Self-pay patients receive a “prompt pay” discount when full payment for services is received on day of appointment. All insurance claims and fees assigned by insurer (such as deductibles, co-insurance, unpaid copays, etc…) are handled by West Denver Endocrinology’s billing service provider (RPM Healthcare billing). A statement will be sent to you. Payment or response is required upon receipt of a statement. Payment plans or other assistance may be offered on an as needed basis. Delinquent accounts will be sent to collections (United Resource Systems) and patient will be responsible for all associated fees. Additional information has also been provided in the payment policy letter.

Please facilitate our goal of providing ideal patient care by complying with West Denver Endocrinology LLC policies. We look forward to collaborating with you to meet your Endocrine health goals. If you have questions, feel free to call or write.

Appointments & Cancellations

With the exception of serious emergencies, it is expected that you keep your appointments. If you need to reschedule an appointment, it is necessary that you advise clinic staff at least 24 hours in advance by calling and leaving a message at 720-330-9760. Patients who cancel an appointment with less than 24 hours notice will be billed a cancellation fee.  Patients who fail to attend appointments without proper notification of cancellation, may also be asked to find another Endocrinology provider. Your consideration in this matter allows West Denver Endocrinology to accommodate other patients who could benefit from an appointment.


West Denver Endocrinology is an outpatient only Endocrinology clinic.  Emergency services are not provided.  If you experience a medical emergency, please dial 911 or go to the nearest emergency room.  



Call 911 or go to an emergency room immediately when someone experiences any of the following:

  • Inability to swallow or “keep down” essential oral medications (especially for patients requiring hydrocortisone)
  • Wheezing, shortness of breath, or difficulty breathing
  • Chest pain
  • Wounds, skin changes, or injuries accompanied by fever, severe pain, dark discoloration, or joint symptoms
  • Bleeding that cannot be stopped
  • Blood in urine, bloody diarrhea, coughing up blood, vomiting blood
  • Intense abdominal pain

  • Uncontrolled high or low blood sugar failing to respond to usual corrective measures or accompanied by changes in mentation, chest pain, abdominal pain, vomiting, shortness of breath, positive ketones, or fruity smelling breath.

The above symptoms list is NOT a complete list. Don’t downplay potentially serious symptoms, if you feel an emergency room visit may be warranted, err on the side of caution and head to the nearest emergency room for evaluation. Also, consider the number of symptoms; multiple seemingly minor symptoms may be significant when they occur all at the same time.


  • If you are needing care right away but symptoms do not meet the above guidelines, you may want to report to an urgent care facility.
  • If possible, call your primary care provider for advice.
  • If primary care provider is not available or if you are requiring care outside of your primary care providers usual office hours, report to the nearest urgent care or after-hours clinic.
