ICD code N95.1 – Menopausal and female climacteric states

Key takeaways

N95.1 is the billable ICD-10-CM code for symptoms of natural, age-related menopause, and it’s a complete code with no child codes.

Report each documented symptom, such as flushing or sleeplessness, as an additional code listed after N95.1.

A menopausal or postmenopausal patient with no documented symptoms is coded Z78.0, not N95.1.

N95.1’s Excludes1 note bars Z78.0, E89.41 (artificial menopause symptoms) and E28.310 (premature menopause symptoms) from the same claim.

Pabau’s claims management software keeps the menopause note, hormone labs and the claim on one patient record.

ICD-10 code N95.1: Definition, billable status and quick reference

ICD-10 code N95.1 is the billable ICD-10-CM code for menopausal and female climacteric states, used for symptoms of natural, age-related menopause. It’s a complete code with no child codes, valid for FY2026 and FY2027. CMS’s FY2027 ICD-10-CM files list N95.1 as a billable code under category N95.

Two questions decide whether N95.1 is the right code. What caused the menopause, and does the note document symptoms? N95.1 fits only when menopause is natural and symptoms are documented. Each symptom then goes on the claim as an additional code. The matrix below maps each pair of answers to its code.

What N95.1 covers: Inclusions and the symptom-code note

N95.1 covers symptoms associated with natural, age-related menopause. The tabular list gives flushing, sleeplessness, headache and lack of concentration as examples. It also carries an instruction to use an additional code for the associated symptoms.

So the two codes share the work. N95.1 tells the payer why the symptoms are happening, and the symptom codes tell it what they are. The alphabetic index points the same way: menopausal flushing, hot flashes and sleeplessness all lead to N95.1.

Adding symptom codes to N95.1

List N95.1 first and the symptom codes after it. Code only the symptoms the physician documents and links to menopause. If a symptom is mentioned but never tied to menopause, query the physician before coding it. Sleeplessness takes the most care, because G47.0 splits into three billable insomnia codes and the note decides which one applies.

What N95.1 excludes: Z78.0, E89.41 and E28.310

N95.1 carries an Excludes1 note with three codes. Excludes1 means the two conditions are never coded together. When the excluded condition is the one documented, its code replaces N95.1.

E28.31 itself is the premature menopause subcategory, not a reportable code. Report E28.310 when symptoms are documented and E28.319 when they aren’t. Both sit in Chapter 4 (endocrine, nutritional and metabolic diseases), as does E89.4-.

The N95 category adds a broader note of its own: disorders due to artificial or premature menopause belong in E89.4- or E28.31-. N95.2 isn’t on N95.1’s Excludes1 list, so atrophic vaginitis can be reported alongside N95.1 when both are documented.

N95.1 vs Z78.0, E28.310 and E89.41: Choosing the right menopause code

Each menopause code in this group answers the same two questions: what caused the menopause, and are there symptoms? Read both answers off the note and the grid below gives you the code.

• No symptoms: A note that says “menopausal state” or “postmenopausal” with no symptoms is Z78.0. The tabular lists menopausal state NOS under Z78.0, not N95.1.
• Natural menopause with symptoms: Report N95.1 with the symptom codes. That pairing is complete, correct coding, with no more specific menopause code to move to.
• Premature menopause: Move to E28.31- only when the physician documents the menopause as premature. Don’t infer it from the patient’s age.
• Early menopause after surgery or radiation: The index sends postsurgical and postirradiation premature menopause to E89.4-, not E28.31-.
• Cause not stated: Query the physician before choosing. The cause moves the code to a different chapter, so a guess here is an Excludes1 risk.

The N95 category: N95.0 through N95.9

Category N95 holds five billable codes in ICD-10-CM, and none of them has subcodes. The category header itself isn’t billable. Knowing all five keeps N95.1 off claims that belong to a sibling code.

Documentation requirements to support ICD-10 code N95.1

A note that supports N95.1 states three facts: menopause, its natural cause and the symptoms it’s producing. The ICD-10-CM Official Guidelines tie code assignment to the provider’s documentation, not to the coder’s reading of the case.

• Diagnosis language: Menopause or a climacteric state named in the assessment, problem list or clinical impression.
• Cause: Natural, age-related menopause, with no premature or postprocedural cause recorded.
• Symptoms: Each symptom named and linked to menopause, so it can be coded after N95.1.
• Menopausal status: The last menstrual period (LMP) date, or an FSH result where one was ordered. This supports medical necessity for hormone labs.
• HRT status: Current hormone replacement therapy (HRT) recorded, with Z79.890 added as a secondary code.

Documentation checklist for N95.1

Common CPT codes and additional diagnosis codes billed with N95.1

N95.1 most often supports office visits and hormone labs. Each of those services is billed with its own code from the CPT code set, and N95.1 is the diagnosis that justifies it.

Three other diagnosis codes regularly travel with N95.1. They describe the context of the visit and don’t replace the symptom codes.

Payer guidelines and coverage considerations for N95.1

Medicare and the major commercial payers accept N95.1 as a primary diagnosis for outpatient gynecology and primary care visits. Coverage varies more at the service level, particularly for HRT and hormone labs. Submitting a clean claim means checking those payer rules before billing, not after a denial arrives.

• Medicare local rules: There’s no national coverage determination for N95.1 itself. Your Medicare Administrative Contractor (MAC) may publish local coverage determinations (LCDs) for hormone labs, so check before billing 82670 or 83001.
• Prior authorization: Some commercial plans require prior authorization for HRT medications. Check at the plan level, because benefit designs vary within one carrier.
• Telehealth: Many payers cover virtual HRT follow-ups. Confirm the place of service code and any modifier each payer requires.
• Lab frequency: Some payers limit how often hormone panels are paid. Check the frequency policy before reordering FSH or estradiol.

Why N95.1 claims get denied, and how to fix them

Most N95.1 denials come from a code that doesn’t match what the note says about cause or symptoms. Building denial management workflows around these five patterns stops the same denial coming back.

• N95.1 on an asymptomatic patient: The note documents menopause but no symptoms, so Z78.0 applies. Fix it by recoding, or query the physician if symptoms were discussed but not recorded.
• N95.1 for premature or postprocedural menopause: Symptoms of premature menopause are E28.310, and symptoms after a procedure are E89.41. Confirm the cause with the physician and recode.
• An Excludes1 pair on one claim: N95.1 next to Z78.0, E28.310 or E89.41 breaks the Excludes1 rule. Keep the code the documentation supports and remove the other.
• Extra characters on N95.1: N95.1 is complete at four characters, so an added digit creates an invalid code that rejects. Check billing templates and cheat sheets for outdated entries.
• Missing LMP or FSH documentation: A payer may deny a hormone lab for medical necessity when the chart lacks objective status evidence. Request an addendum documenting the clinical basis.

Coding scenarios for ICD-10 code N95.1

These five cases cover the coding calls OB-GYN and primary care teams make most often around this code. Each one turns on what the note documents about cause and symptoms. OB-GYN and primary care practices can build both questions into their menopause visit templates.

Scenario 1: Menopause with no documented symptoms

A 52-year-old established patient attends a well-woman visit. The physician documents: “Postmenopausal, last menstrual period 14 months ago. No hot flashes, night sweats or sleep problems. Counseled on bone health.”

Correct coding: Z78.0 (asymptomatic menopausal state). The note rules out symptoms, so N95.1 doesn’t apply. Z78.0 is an Excludes1 of N95.1, so the two never appear together.

Scenario 2: Hot flashes and sleeplessness in natural menopause

A 51-year-old patient, last period 13 months ago, reports hot flashes several times a day and trouble sleeping. The physician documents: “Symptomatic natural menopause with vasomotor symptoms and insomnia. Continue HRT.”

Correct coding: N95.1 (primary), R23.2 (flushing), the G47.0- insomnia code the note supports, and Z79.890 (HRT). N95.1 has no more specific code to move to. The symptom codes carry the detail.

Scenario 3: Symptomatic menopause with osteoporosis

A 56-year-old patient on HRT attends a combined menopause and bone health review. The physician documents: “Ongoing night sweats related to menopause. DEXA shows osteoporosis, no fracture. Continue HRT.”

Correct coding: N95.1 (primary), R61 (night sweats), M81.0 (age-related osteoporosis) and Z79.890 (HRT). M81.0 is an Excludes2 of the N95 category, so it can be reported on the same claim.

Scenario 4: Premature menopause

A 38-year-old patient has been on HRT for six months. The physician documents: “Symptomatic premature menopause, hot flashes persisting. FSH 92. Continue HRT.”

Correct coding: E28.310 (symptomatic premature menopause) and Z79.890. N95.1 would be wrong here, because E28.310 is an Excludes1 of N95.1. Premature menopause is a Chapter 4 endocrine condition.

Scenario 5: Symptoms after bilateral oophorectomy

A 47-year-old patient had a bilateral oophorectomy three months ago. The physician documents: “Flushing and poor sleep since surgery, consistent with surgical menopause.”

Correct coding: E89.41 (symptomatic postprocedural ovarian failure). Symptoms of artificial menopause are an Excludes1 of N95.1. The E89.41 inclusion term covers flushing and sleeplessness after postprocedural menopause.

How Pabau keeps N95.1 claims matched to the menopause note

In most practices, the note and the claim are built by different people on different days. The physician records symptoms and history at the visit. Later, someone at the billing desk reads that note and picks a code. When the note is vague about symptoms or cause, the pick can land on the wrong side of Z78.0 or E28.310.

Pabau, the practice management and billing platform we build, keeps the visit note, lab results and claim on one patient record. With labs switched on, FSH and estradiol results from Quest or Labcorp come back into that record automatically. The status evidence sits beside the diagnosis it supports.

Pabau’s claims management software sends US claims through Claim.MD as CMS-1500 claims, with eligibility checked before the visit. Prior authorization for HRT is tracked on the patient’s case, with a warning when an authorization code is missing. Your billing team codes from what the physician wrote, in the same place the physician wrote it.

Keep N95.1 claims in step with the note

Pabau puts the visit note, hormone lab results and the claim on one patient record. Your billing team codes from what the physician documented, and US claims reach payers through Claim.MD.

Conclusion

N95.1 is a narrow code with a clear rule. It’s the complete, correct code when natural menopause is producing documented symptoms, with each symptom coded beside it. Use it for an asymptomatic patient, or for premature or postprocedural menopause, and the claim no longer matches the note.

The fix sits upstream of coding. Make cause and symptoms explicit in every menopause note, then code from the grid, and Excludes1 rejections stop recurring. Book a demo to see how Pabau keeps menopause notes, hormone labs and claims on one record for your billing team.
