At Singular Sleep, many of our patients have high-deductible health plans with or without health care spending accounts (HSA) or flexible spending accounts (FSA). These patients often find that they can save a lot of money and time by using us to get a sleep apnea test, consult with our sleep doctor, and purchase CPAP and BPAP products. But folks often want to submit invoices to their insurance companies for reimbursement or to count towards their deductibles. Here is some helpful information that can make it easier for you to file claims with your health care insurance company. Below are the most common codes that we use:

What are the ICD-10 codes for sleep apnea?

What are the CPT codes for a home sleep apnea test and my online sleep doctor consultations?

Current Procedural Terminology (CPT ) codes are used for health care provider services and medical procedures.

For the home sleep testing units that we use, the most appropriate CPT code is 95806.

Note: some insurers require - or also accept-  the "G code"  G0399 for a home sleep study. G codes are from the HCPCS (see system below).

Evaluation and management codes - also known as E&M or E/M codes

E&M codes are a subset of CPT codes used for medical evaluations by health care providers. The most appropriate codes to use for your sleep doctor consult are:

Office or other outpatient visits: 99220 - 99215; complexity of the medical encounter will determine the exact code to use.

What are the HCPCS codes for my CPAP machine and mask?
