Detailed Breakdown
Let’s dive deeper into the intricacies of billing for photochemotherapy and related dermatological services. Understanding each component, from the core CPT codes to the specific guidelines, is paramount for accurate and compliant billing.
Understanding CPT Code 96910: Photochemotherapy (PUVA)
The 96910 cpt code represents a critical service in dermatological treatment, specifically for photochemotherapy. This code encompasses both the Goeckerman treatment (tar and ultraviolet B) and psoralens and ultraviolet A (PUVA) light therapy. While both are covered under 96910, their clinical applications and specific protocols differ significantly.
Components of 96910 Service
When billing for cpt 96910, you’re essentially billing for a comprehensive therapeutic session. For PUVA, this typically involves:
- Psoralen Administration: This photosensitizing agent (e.g., methoxsalen) is administered orally or topically prior to UV exposure. Its purpose is to make the skin more sensitive to UVA light, enhancing the therapeutic effect.
- Ultraviolet A (UVA) Light Exposure: The patient is exposed to a controlled dose of UVA light in a specialized booth or unit. The duration and intensity are carefully calibrated based on the patient’s skin type and response.
- Physician Supervision: Direct or indirect supervision by a physician is required. This includes determining the treatment parameters, monitoring the patient’s response, and managing any adverse effects.
It’s crucial to distinguish 96910 from other phototherapy codes. The presence of a photosensitizing agent (psoralen) is the defining characteristic of PUVA, differentiating it from standard UVB phototherapy (e.g., 96900 cpt code).
Billing Frequency and Units
CPT 96910 is typically billed per session. Most payers, including Medicare, expect one unit per treatment day, regardless of the number of lesions or areas treated, as it’s considered a whole-body or extensive regional treatment. However, always verify specific payer policies, as some may have unique interpretations or require additional documentation for multiple sessions within a very short timeframe (e.g., twice daily, which is rare for PUVA).
Medicare NCD/LCD Guidelines for 96910
This is where precision is paramount. Medicare’s coverage for cpt code 96910 is governed by both National Coverage Determinations (NCDs) and Local Coverage Determinations (LCDs). Ignoring these guidelines is a direct path to denials.
National Coverage Determinations (NCDs)
While there isn’t an NCD specifically titled “96910,” phototherapy services fall under broader NCDs. For instance, NCD 20.29, “Phototherapy for Psoriasis and Other Skin Conditions,” provides general guidance on the coverage of various phototherapy modalities. This NCD establishes the medical necessity for conditions like severe psoriasis, vitiligo, and cutaneous T-cell lymphoma (CTCL) when other treatments have failed or are contraindicated. 96910, as a form of phototherapy, must align with the general principles outlined in such NCDs.
Local Coverage Determinations (LCDs)
The real granular detail for 96910 cpt code coverage lies within your specific Medicare Administrative Contractor’s (MAC) LCDs. These are non-national policies that provide more specific details on medical necessity, frequency, and documentation. You must consult the LCDs for your region. Here’s what to look for:
- Covered Diagnoses (ICD-10 Codes): LCDs will list specific ICD-10 codes that support medical necessity for 96910. Common examples include L40.0 (Psoriasis vulgaris), L80 (Vitiligo), and C84.0x (Mycosis fungoides). If your patient’s diagnosis is not on the list, coverage is unlikely without an extensive appeal.
- Frequency and Duration Limits: Many LCDs specify the maximum number of treatments allowed per week, month, or year, and the total duration of a treatment course. Exceeding these limits without robust justification will lead to denials.
- Documentation Requirements: Expect detailed requirements for patient records, including:
- Severity of the condition (e.g., PASI score for psoriasis).
- History of failed prior therapies (e.g., topical steroids, systemic agents).
- Rationale for choosing PUVA over other treatments.
- Patient’s response to treatment, including cumulative dose.
- Absence of contraindications.
- Specific Treatment Protocols: Some LCDs may detail specific requirements for psoralen administration (oral vs. topical) or types of UVA equipment.
- Prior Authorization: For certain diagnoses or extended treatment courses, prior authorization may be mandated by your MAC.
Actionable Advice: Always consult your specific MAC’s LCD for CPT 96910 to ensure compliance. A quick search on your MAC’s website for “Phototherapy” or “PUVA” LCD will yield the necessary document.

The Goeckerman Regimen and CPT 96910 Nuances
The Goeckerman regimen is an intensive, highly effective treatment for severe, recalcitrant psoriasis. It involves the daily application of crude coal tar, followed by UVB phototherapy, often combined with emollients and other topical agents. While the CPT description for 96910 explicitly mentions “tar and ultraviolet B (Goeckerman treatment),” it’s crucial to understand how to bill for the various components of this complex regimen.
Billing Goeckerman Components
When a patient undergoes a Goeckerman regimen, 96910 is billed for the photochemotherapy component (specifically, the tar and UVB exposure). However, the regimen involves more than just light therapy:
- 96910 for the Phototherapy: This code covers the application of tar (if performed by the physician/staff) and the subsequent UVB exposure. It’s typically billed once per day of treatment.
- Other Topical Applications: The application of other emollients or topical medications by staff may be considered incidental to the facility charge or bundled into the 96910 service. If a physician performs a separate, distinct procedure, it might be billable, but this is rare.
- Physician Visits (E/M Codes): Daily physician evaluation and management (E/M) services are often necessary to monitor the patient’s progress, adjust treatment, and manage side effects. These E/M services (e.g., 99213, 99214 for outpatient; 99231-99233 for inpatient/observation) can be billed separately if they meet the criteria for a significant, separately identifiable service on the same day as 96910. In such cases, append modifier -25 to the E/M code.
- Facility Charges: If the Goeckerman regimen is performed in a hospital outpatient department or a specialized day treatment center, the facility will bill for its resources (room, supplies, nursing care) using appropriate facility codes.
Important Note: The keyword “cpt #TAB#96922” appears to be a typo, likely intending to refer to CPT 96922. CPT 96922 is for photodynamic therapy (PDT), which is a distinct procedure from Goeckerman or PUVA. PDT involves a photosensitizing agent (e.g., aminolevulinic acid) and a specific light source to treat conditions like actinic keratosis or certain skin cancers. It is NOT used as part of the Goeckerman regimen. We will discuss 96922 in more detail below to clarify its appropriate use. Learn more about E/M coding in our 2025 E/M Guidelines article.
Related and Ancillary CPT Codes
A clear understanding of related codes prevents incorrect billing and ensures you select the most appropriate service for the procedure performed.
96900 CPT Code: Ultraviolet Light Therapy (UVB)
The 96900 cpt code is for “Phototherapy (ultraviolet B) light therapy, whole body.” This code is used for treatments involving broadband or narrowband UVB light, without the use of a photosensitizing agent like psoralen. It’s commonly used for conditions such as psoriasis, eczema, and vitiligo. The key differentiator from 96910 is the absence of psoralen. If you’re performing standard UVB phototherapy, 96900 is the correct code, not 96910.
96922: Photodynamic Therapy (PDT)
As mentioned, 96922 is for “Photodynamic therapy, each additional 10 sq cm or part thereof (List separately in addition to code for primary procedure).” This is an add-on code used in conjunction with a primary PDT code (e.g., 96920 for up to 5 sq cm, 96921 for 5.1 to 10 sq cm). PDT is a two-stage treatment that uses a photosensitizing drug and a specific type of light to treat precancerous and cancerous lesions. It is fundamentally different from PUVA or Goeckerman and should not be confused with them. Ensure you use the correct primary PDT code (96920 or 96921) before adding 96922 for larger areas.
96999: Unlisted Special Dermatological Service or Procedure
The 96999 code is reserved for “Unlisted special dermatological service or procedure.” This code should be used sparingly and only when no other CPT code accurately describes the service performed. If you must use 96999, be prepared for extensive documentation requirements. You’ll need to provide a detailed description of the procedure, its medical necessity, and a comparison to a similar existing CPT code in terms of complexity, time, and effort. Prior authorization is almost always required for unlisted codes.
Clarifying +91 97172 96922
The keyword string “+91 97172 96922” appears to combine several distinct elements. Let’s break it down:
- +91: This is not a standard CPT modifier or code prefix in the U.S. medical billing context. It might be a typo or refer to an international dialing code. In U.S. billing, modifiers are two digits (e.g., -25, -59).
- 97172: This CPT code is for “Therapeutic procedure, 1 or more areas, each 15 minutes; manual therapy techniques (e.g., mobilization/manipulation, manual lymphatic drainage, manual traction), one or more regions, each 15 minutes.” This code is typically used by physical therapists, occupational therapists, or chiropractors for manual therapy. It is not appropriate for billing photochemotherapy or any form of light therapy. Using 97172 in conjunction with 96910 would be incorrect and would likely result in a denial.
- 96922: As discussed, this is an add-on code for photodynamic therapy.
It’s crucial to understand that 97172 has no direct relation to photochemotherapy or the Goeckerman regimen. Avoid using it in this context.
Modifiers for CPT 96910
Modifiers are two-digit codes that provide additional information about a service or procedure, clarifying circumstances without changing the meaning of the CPT code itself. Correct modifier usage is critical for preventing denials.
- -25 (Significant, Separately Identifiable Evaluation and Management Service): Append this modifier to an E/M code (e.g., 99213) when a significant, separately identifiable E/M service is performed on the same day as 96910. The E/M service must be distinct from the decision to perform the photochemotherapy or the routine pre/post-procedure care. Document clearly why the E/M was separate.
- -59 (Distinct Procedural Service): Use -59 to indicate that a procedure or service was distinct or independent from other services performed on the same day. This is often used to bypass National Correct Coding Initiative (NCCI) edits when two procedures that are typically bundled are legitimately performed separately. For example, if 96910 and another minor procedure are performed on the same day, and they are not typically bundled, -59 might be appropriate on the second procedure.
- -76 (Repeat Procedure or Service by Same Physician or Other Qualified Health Care Professional): If the same physician or qualified healthcare professional repeats 96910 on the same day (e.g., due to equipment malfunction requiring a second full session), append -76 to the second instance.
- -77 (Repeat Procedure by Another Physician or Other Qualified Health Care Professional): Similar to -76, but used when a different physician or qualified healthcare professional repeats the procedure on the same day.

Documentation Requirements
Robust documentation is your strongest defense against audits and denials. For 96910, ensure your records clearly demonstrate:
- Medical Necessity: A clear diagnosis (ICD-10) that supports the use of photochemotherapy, along with a detailed rationale for why 96910 is the appropriate treatment.
- Treatment Plan: Initial assessment, goals of therapy, type of psoralen used (if applicable), light source (UVA/UVB), initial dose, and planned frequency.
- Session Details: For each visit, record the date, time, specific light dose (Joules/cm²), duration of exposure, and any psoralen administration details.
- Patient Response: Document the patient’s reaction to treatment, improvement in condition, and any adverse effects.
- Physician Supervision: Note the level of physician involvement for each session.
- Failed Prior Therapies: For conditions like psoriasis, document previous treatments attempted and
FAQ: Common Questions Answered
What is the 2026 Medicare reimbursement rate for CPT 96910?
While this guide focuses on the critical billing nuances and guidelines for CPT 96910 as of 2025, it does not specify the exact Medicare reimbursement rates for 2026 or any other year. Reimbursement rates are subject to annual updates by CMS and can vary based on geographic location and specific payer contracts. To ascertain the precise 2026 Medicare reimbursement rate, practices should consult the official Medicare Physician Fee Schedule (MPFS) once it is released for the upcoming year, or refer to their specific Medicare Administrative Contractor (MAC) fee schedules.
Can CPT 96910 be billed with CPT 96912, and what are the rules?
The provided article details the billing for CPT 96910 (Photochemotherapy) and briefly mentions CPT 96900 (Phototherapy, whole body). However, it does not include CPT 96912 in its quick reference guide or discussion. Therefore, specific rules regarding the co-billing of CPT 96910 with CPT 96912 cannot be derived from this text. When considering billing multiple phototherapy codes or combining them with other services, it is imperative to consult the National Correct Coding Initiative (NCCI) edits, payer-specific policies, and the CPT manual to understand bundling rules, modifier requirements (e.g., -59 for distinct procedural service), and medical necessity criteria to prevent denials.
What are the MUE limits for CPT 96910 and related phototherapy codes?
This article emphasizes optimizing financial health and minimizing denials, but it does not explicitly detail the Medically Unlikely Edits (MUEs) for CPT 96910 or other phototherapy codes. MUEs are unit-of-service edits that represent the maximum number of units a provider would report under most circumstances for a single beneficiary on a single date of service. Exceeding MUE limits without proper justification or appropriate modifiers can lead to claim denials. Practices must regularly consult the CMS MUE file, available on the CMS website, and their specific MAC’s guidelines to ensure compliance and accurate unit reporting for CPT 96910 and all related services.
How do Medicare NCD/LCDs impact billing for CPT 96910?
Medicare National Coverage Determinations (NCDs) and Local Coverage Determinations (LCDs) are absolutely critical for billing CPT 96910. As highlighted in the article, adherence to these guidelines dictates whether photochemotherapy services like Goeckerman treatment or PUVA will be covered and reimbursed by Medicare. NCDs and LCDs specify the medical necessity criteria, covered diagnoses (e.g., severe psoriasis, vitiligo, CTCL), frequency, duration, and sometimes even the specific documentation required to support the service. Non-adherence to these detailed policies is a primary reason for claim denials, making it essential for practices to thoroughly understand and implement the most current NCD/LCDs relevant to CPT 96910 for their specific jurisdiction.
